What are the types of wood cutters for a manual router. Working with a manual wood router: features and video tutorials How to work with a manual wood router lesson

If you are interested in carpentry, you should definitely understand how to work with a hand router. The milling cutter allows you to create a variety of crafts without making almost any effort. However, before starting, you need to familiarize yourself, firstly, with the features of the structure and use of the tool, and secondly, directly with the technology of work. By learning how to work as a wood router, you can decorate furniture, doors and any other wood items. If you wish, you can even start your own small business.

The device of a manual milling cutter: 1. Base - plywood (acrylic, mdf); 2. Cutter 6 mm.; 3. Reciprocal hole in the base of the router; 4. What should happen; 5. Hairpin (a nail without a cap is good).

What kind of work can be done with a manual router

With a wood router, you can perform work of a diverse nature and varying complexity. At its core, a milling cutter is a device that performs many rotations at high speed, creating holes of the required shape and size. All the work that a manual router allows you to do can be divided into several main categories. So, using this tool, you can mill quarters, grooves and grooves. The holes created with the tool are usually part of a prefabricated structure or a decorative element.

Before starting work with a manual router, you need to consider the main features of each existing type of work. The first is profiling. With a manual milling cutter, you can profile platbands, cornices, skirting boards, glazing beads and other products. This is done with an edge. This type of work is usually used in the manufacture of furniture. An excellent option for decorating wooden products.

With a manual router, you can decorate the edges of various complex products, creating a truly exclusive product. Each master has his own idea of how the finished product should look, so the output is often real masterpieces. For beginners, it is better to take on such work after they gain experience. Experts advise doing this work only using a template.

A manual milling cutter allows you to solve many common household tasks, for example, to make recesses for locks. In production conditions, as a rule, special milling machines are used, but at home you can get by with a simple hand tool.

In the process of working with a router, you will need various additional tools and accessories. Their list will vary depending on what specific work you are going to do, but the following are used most often:

Electric jigsaw.
Electric drill with drills.
Iron plate, screws.
cutter.
File.
Templates.
Overalls, respirator.

When processing wooden products, special cutters are used. Choose them according to the type of work to be done. Consider also the type of material being processed. Each of them has its own characteristics and requires the use of appropriate cutters.

The cutter itself is part of the design of the tool in question. It consists of a working part with a cutting edge and a shank. Cutters may differ from each other in design features, size, material of manufacture, shape of the cutting part.
For processing soft wood, milling cutters made of light material are suitable. If you have to process a harder wood, select the appropriate hard cutters.

There is a generally accepted classification of this structural element. Cutters are usually divided into:

Profile. They are used for decorating various wood products.

Conical. With their help, you can process wood of various species at an angle.

Rectangular. Used for grooving.

V-shaped. Allows you to create holes with an angle of inclination of 45 °. Usually used for applying various kinds of inscriptions on the surface of wood products.

Kalevochnye. Used for rounding edges.

Disk. With their help, in a wood product, you can create horizontal grooves of different widths and depths.

Folded. Used for cutting quarters.

"The swallow nest". Designed specifically for making stud joints of hidden and open type.

Fillet. Allows you to create fillets on the edges of wood products.

In addition, there is a classification of cutters into bearing and non-bearing. Hand tools without bearings in all cutters allow you to process the workpiece in any required place.

Step-by-step instructions for installing the cutter

First of all, the cutter must be set to the required depth. This is done in the following order:

Choose a cutter to create the hole you want in the wood.

Insert the shank of the selected product into the chuck so that the immersion is no more than 20 mm.

Turn the cartridge until it clicks and tighten its nut with a wrench.

To set the router to the desired depth, use a special tool called a movable depth setting stop.

Set the fine adjustment knob between minus and plus.

Before proceeding with the processing of the finished product, be sure to check how deep the cutter will enter on the finished sample. If the entry is not as desired, you can independently set the required depth using the knob designed for this.

Basic rules for working with the tool

It is very important to set the speed controller correctly. If this is not done, the workpiece may be damaged. In particular, the risk of damage to the workpiece becomes greater when working with a large diameter cutter.

Select the speed according to the features of the work to be done and the characteristics of the materials. The more correct the ratio of the frequency of rotation of the cutter in relation to the characteristics of the processed wood, the more high-quality and clean the work will be.

When choosing a milling cutter, it is necessary to pay attention to the working field, the optimal size of which is 12000x1200 mm, and to the power of the tool.

With an increase in the diameter of the cutter, the frequency of rotation must be reduced. For example, cutters with a diameter of 1 cm can be used at a speed of about 20,000 rpm, and a product with a diameter of 4 cm is better to work at speeds up to 10,000 rpm. Each cutter comes with instructions. Make sure you have it when you buy the instrument. The instructions indicate all the requirements that must be met to obtain a good result.

During operation, you can hold the router with your hands or fix it on the table. It is more convenient and preferable to process small products on the table. In this case, the work will be of the highest quality. The installation of the router on this kind of table is carried out with the spindle up. If you wish, you can also buy or assemble a machine with your own hands.

Milling wood on a table requires the following rules:

A ruler should be placed on the surface of the table under the shape that is planned to be cut. If a semicircle is cut, arcuate guides are used. In the case of creating lines, the guides must also be even.

When working with details of a variable profile, use narrow rulers with an oval end. Attach them perpendicular to the workpiece.

When working with a milling cutter, do not forget that the milling cutter must be moved along the workpiece only in the opposite direction to the movement of the cutter. Otherwise, you risk not holding the tool and injuring yourself.

There are different types of manual routers, however, the most used and versatile can be called a manual plunge mill, which is described below. Plastic wood, perfect in its aesthetics, and a universal manual milling cutter. This combination allows you to get products of almost any shape - from the simplest in the form of straight planes, to the most complex, more suitable for works of art than for utilitarian things. Working with a manual wood router is an opportunity to fully enjoy creativity, creating original, exclusive products.

Types of work performed by the milling cutter

All operations that are carried out using a manual router can be divided into several categories.

Milling grooves, grooves, quarters and other recesses in the workpiece, which can be located both along and across the layers, be open (exit to the edge) or closed. With some exceptions, these forms perform certain structural functions - most often they form detachable and one-piece connections.

Edge milling- profiling. It is used for the production of molded profile products (cornices, skirting boards, platbands, glazing beads, etc.), as well as for interior design, furniture manufacturing and various kinds of handicrafts. These elements, in addition to being functional, also carry a decorative load.

Milling complex surfaces and contours in the creation of original furniture, exclusive interiors and the manufacture of products for various purposes, claiming to be artistic sophistication. At the same time, templates are widely used that allow copying repeating complex shapes with great accuracy, making them almost completely identical.

Milling special features carrying a purely functional load. These are grooves and holes for awnings and locks, spikes, etc. In serial production, these elements are made by specialized milling cutters (filler, etc.). But in everyday life, universal manual milling cutters quite successfully cope with them.

A manual milling cutter processes wood with the help of special milling cutters, consisting of a cylindrical shank (collets for shanks with a diameter of 6, 8 or 12 mm are more common) and a working part with a cutting edge. There is a huge number of cutters that differ in size and design, the shape of the cutting edge, material. For soft woods, cutters with knives made of high-speed tool steel are used, for hard materials (oak, ash, beech, aluminum, etc.) - from hard alloys.

To give the product a certain shape, it is necessary to ensure the exact positioning of the cutter relative to the workpiece in three coordinates. The position of the tool in a vertical position is ensured by the immersion mechanism, which moves the motor with the cutter along the vertical guides of the bed and stops it in the desired position in height.

Positioning in the horizontal plane can be achieved in various ways. With a guide bearing mounted on the router bit, or a guide bushing attached to the bearing surface of the router, as well as a variety of special tools that come with routers and are purchased independently or made by yourself. There are a large number of manuals and recommendations describing how to work with a router using these devices, read one of them.

When using cutters with a guide bearing, the latter rolls along the edge of the workpiece or template located below or above the workpiece, thus providing a certain distance between the cutter and the workpiece. Milling cutters with a guide bearing and processing edges of parts are called edge cutters. They are used only for processing the edges of workpieces. There are different types of edge cutters.

Profile cutters(a and b) give the edge various curly profiles that carry a decorative load.

cone cutter(c) designed for bevelling at an angle of 45°.

Moulder cutter(d) used for rounding edges. It forms a profile in a quarter of a circle and comes in different sizes with a circle radius of 3-16 mm.

Disc cutter(e) cuts a horizontal groove of various depths and widths in the workpiece.

Rebated cutter(e) is used for milling quarters that perform a variety of functions.

Fillet cutter(g) is used to obtain fillets on the edge. It is used to give the edges a decorative effect.

Milling cutters without guide bearings, called slot cutters, are designed to machine the workpiece anywhere. Their use requires the use of devices (read about branded and home-made devices for a manual router), which ensure the positioning of the cutter in a horizontal plane.

Rectangular groove cutter(a) is perhaps the most used. It is used for milling grooves that ensure the connection of parts - both one-piece and detachable.

Fillet cutter(b) creates semicircular grooves or grooves in the workpiece, often performing decorative functions.

V cutter(c) forms a groove with walls at an angle of 45°. If you insert the cutter to a greater depth, you get a groove with vertical edges. With the help of a V-shaped cutter, letters and various decorations are cut out.

Cutter "dovetail"(d) is usually used in furniture production for open and hidden tenon joints.

Mounting the cutter in the collet of the router

The installation of the cutter can be carried out both in the engine, taken out of the bed, and located in it. It is carried out in the following sequence:

The cutter is laid on its side.
The spindle is fixed from rotation - depending on the design of the router, with a wrench or a locking button.
Release (if it is screwed onto the collet) or screw on the clamping nut of the collet.
The shank of the cutter is inserted into the collet until it stops or at least 20 mm.
Using a wrench (if the spindle is fixed with a wrench, a second wrench is required), the clamping nut is tightened, the spindle is unlocked.

If there is no cutter in the collet, the clamping nut must not be tightened. This may damage the collet..

Working with a milling cutter involves performing various adjustment operations. One of the main ones is setting the depth of milling. It may vary slightly for milling cutters of different models, but its principle for all plunge cutters remains the same. The essence of the setting is that when the cutter reaches the required depth, the immersion limiter rests against the turret stepped stop and prevents further immersion of the cutter.

Milling depth setting: 1 - turret stop, 2 - immersion depth limiter, 3 - depth stop locking screw, 4 - limiter slider, 5 - fine-tuning mechanism, 6 - immersion scale, 7 - spindle lock for installing the cutter.

The operation is performed in the following order:

The milling cutter is installed with a supporting surface on the workpiece.
The turret stop, which sets the immersion depth, is set with its lowest stop opposite the limiter end.
The limiter locking screw is released, as a result of which the latter acquires the ability to move freely in its guides.
The immersion (lowering) mechanism of the router is unlocked.
The motor slowly lowers down until the cutter touches the workpiece.
The engine lowering mechanism is again blocked.
The depth gauge is lowered until it touches the lowest stop.
The limiter slider is set to "0" of the dive scale.
The limiter rises to the position at which its slider shows on the immersion scale the value of the milling depth that you want to set. This operation can be done by raising and lowering the limiter by hand (coarse setting) or by using the fine adjustment mechanism (fine setting).
The limiter locking screw is clamped, fixing the slider in the set position.
The plunge mechanism is unlocked and the cutter moves up with the motor.

Now, if you lower the motor with the cutter to the lowest position (until the end of the limiter touches the shortest pin of the turret), the cutter will penetrate into the workpiece to the depth, the value of which is set on the scale.

If milling is carried out to a greater depth, it must be carried out in stages. This is done by turning the turret in such a way that during the first passes the depth gauge rests first on the higher stops and only on the final pass on the lowest stop.

Choice of cutter speed mode

Unlike rotary hammers, screwdrivers and drills, the speed of rotation of the cutter is relatively high - usually over 10,000 rpm. This is because the faster the cutter rotates, the cleaner the cut surface is. However, too high speeds are also undesirable, since the surface to be machined can be charred, and excessively increasing centrifugal forces - especially when using large diameter cutters - can lead to breakage. Therefore, the speed of rotation of the cutter is regulated within certain limits depending on the material being processed and the diameter of the cutter.

In fact, the cleanliness of the machined surface is determined not by the rotation speed of the cutter, but by the linear speed of the cutting edge relative to the material. The larger the cutter diameter, the higher the linear speed. Therefore, when using cutters with a large diameter, the rotation speed is set lower. For example, for a cutter with a diameter of 10 mm, the speed should be from 20,000 rpm and higher, for a cutter with a diameter of 40 mm - 10,000-12,000 rpm. Specific values are given in the operating instructions. The rotation speed is also determined by the hardness of the material being processed. The higher the hardness, the lower the number of revolutions of the cutter should be.

After prolonged operation at low speed, the router should be run for several minutes at maximum idle speed to cool the engine..

Direction of cutter rotation

The direction of rotation of the cutter can be forward or backward. At the first, the cutting edge of the cutter moves relative to the material in the direction opposite to the movement of the router (the edge cuts into the rough surface of the board and exits at the bottom of the milled groove). In up milling, the edge of the cutter moves in the same direction as the movement of the router (plunging starts at the depth of the slot). The up-cut milling is correct, the down-cut milling is used only in exceptional cases - when processing edges in which the location of the fibers leads to flakes. This method is considered unsafe, as it can lead to tearing the router out of your hands.

Milling

Milling parts with a manual router, as a rule, is associated with the use of various devices that ensure the exact position of the router. Therefore, milling techniques are discussed in the article Milling fixtures, which describes not only branded fixtures, but also do-it-yourself ones.

Before starting milling, the following must be done:

The cutter is fixed in the collet.
The correct engine speed has been set for the job.
The required milling depth has been set using the plunge limiter (when working with plunge cutters) or a certain overhang of the cutter in relation to the sole has been fixed (when working with edge cutters).
A guide bearing or ring (when working with edge cutters) or other device is installed to provide the necessary path of the cutter. In this case, the optimal cut thickness should be set - as a rule, no more than 3 mm.

The methods of working with a manual milling cutter differ somewhat depending on the mode in which the work is carried out. But in any case, the milling cutter is installed on the base - the workpiece or the auxiliary surface. The guide element of the router (bearing, ring, edge of the sole or other surface) is pressed against the guide edge (part, rail or template), after which the engine is turned on and the cutter is first immersed (if using the immersion mode), then the router smoothly moves along the trajectory , given by the guide element.

Basic safety measures when working with a router

Safety measures are described in detail in the operating instructions for the router. The most important ones that are simply vital to know include the following:

Fastening the cutter and setting up the router must be carried out with the power cord unplugged from the outlet.
Working with a manual milling cutter requires care and concentration. When milling, it is necessary to stand steadily on your feet and firmly hold the router in your hands. You can't work when you're tired, distracted, or drunk. This could cause the router to be pulled out of your hands and cause serious injury.
The workpiece must be firmly fixed, otherwise it can be torn off by the cutter from its place and thrown with great force and speed.
During the contact of the cutter with the material, you must be especially careful to avoid the so-called kickback - the effect when the cutter hits the material and receives a reactive blow in return, which can lead to the router being pulled out of the hands, breaking it or causing injury. To prevent a kickback, you need to firmly hold the router in your hands, firmly press it to the base and move the tool smoothly. The thickness of the cut layer should not be too large - no more than 3 mm.
Clothing should not have dangling elements - those that can be wound around the cutter.
Avoid inhalation of fine dust generated during milling. It's bad for the lungs. Dust can be sucked off with a vacuum cleaner or you can use a respirator.

In the tool kit of many home craftsmen, a milling cutter takes pride of place. A universal router is an electrical device designed to process the surface of wood or metal products. The milling machine simplifies the work of manufacturing a variety of products, creating recesses for loops, various grooves.

For these works, expensive and professional equipment is not necessary at all: a simple universal tool is enough.

With the help of a milling cutter, you can make a lot of household items and carry out any operations with wood or metal. Milling cutters are needed for processing flat and shaped surfaces. These tools create technological recesses, grooves for various connections, and even complex patterns that serve as decorations.

Milling cutters differ in the installation method - these are stationary machines and manual milling cutters. Machine tools, in turn, differ in the type of operations performed.

Stationary devices are placed in large factories or factories - where it is necessary to manufacture a large number of parts of the same type. The cutting nozzle in them is fixed motionless, and the part that is being processed moves.

The most versatile and suitable for a wide range of tasks are hand-held electric mills. When using a hand tool, the workpiece is fixed rigidly, and the tool itself moves. In milling cutters, there is a constructive ability to fix the tool, so manual devices are recognized as more versatile.

To change the type of work, it is enough to change or position the nozzle in a different way.

In particular, what can be done with a manual wood router, which has the right equipment:

The wide possibilities of this tool allow it to be used by both professional construction or repair teams, and novice home craftsmen.

It is indispensable in the manufacture of interior decorations, the production of furniture or the creation of various crafts.

Universal router device

To maximize the use of a manual device, the master must be guided in the design of the device and the purpose of its main parts.

The main part is an electric motor hidden in the body. Holders with collets are inserted into the body. Collets are adapters for the use of milling cutters of various sizes.

The cutter is inserted into the collet and fixed with a special button or clamping bolt.

The body is placed on the platform with two rods. The platform is made of metal and is quite massive and stable. Attached to the bottom of the platform is a smooth sliding plate that allows the tool to move smoothly over the part.

The case also houses the "Start" button and the tool lock button. The operating mode is selected using:

Knobs and setting scales that can be used to adjust the depth of milling. They allow you to adjust the depth with an accuracy of 1/10 mm.
Speed switch. For those who are just starting to get acquainted with the tool, it is recommended to work at medium and even low speeds.

In some modifications, there is a parallel stop that allows you to move the cutting part to the left or right. This is very convenient for some types of wood milling.

According to their purpose, hand-held devices are conditionally divided into the following types:

Upper.
Kromochny.
Lamella.

Top-type milling cutters are fixed or submersible. In stationary devices, the cutting part cannot move along the body. Therefore, to adjust the depth of processing, the master is forced to move the entire tool, which requires certain skills and experience.

When choosing a unit, preference is often given to plunge cutters. In them, the motor is located on guides along which it can move along with the cutting part. In addition, in the submersible type of devices there is a spring responsible for raising the nozzle at the end of work.

Milling wood with a manual edge-type router is the chamfering and processing of the edges of workpieces. When using different nozzles, it is possible to process not only straight, but also curly surfaces: for example, to make skirting boards or process curly door panels.

The lamellar type is used to create various grooves. Of all types of hand routers, it is the most highly specialized.

Tool selection rules

The choice of a suitable type of electric cutter depends on the technological tasks set. Based on them, a device with optimal functionality and suitable technical characteristics is selected. In addition, the need and availability of additional devices is taken into account. These are clamps, different stops, templates, with the help of which the workpiece is processed more accurately and safely.

First of all, a device with suitable power is selected. The mass of the tool depends on this characteristic. Therefore, manual routers are divided into light, medium and heavy.

Lightweight devices with a minimum mass have a power of no more than seven hundred and fifty watts. The middle category has a power of up to one thousand one hundred watts. For heavy devices, this value is more than one thousand two hundred watts.

In the case of simple and non-intensive tasks, or if the processing material is exclusively wood, the acquisition of a high-power device is not justified. Very powerful tools have a low shaft speed.

The speed of rotation of the router is also one of the important characteristics of the tool. The speed indicator ranges from 7,000 to 24,000 rpm. Different materials and types of work for processing require different rotation speeds.

Brittle and hard materials and large cutting depth require a low-speed powerful tool. High speed devices are suitable for polishing, grinding, engraving or for processing wooden parts.

When choosing a device, the location of the on / off button is important. The convenience for the hands, and hence the speed of processing the workpieces, depends on this.

Collets differ in material, workmanship and their design. The best collets are cone-shaped and made of hardened steel. Such elements wear out less and last much longer than collets, which are made of ordinary steel.

Modern routers are often equipped with a built-in dust removal element during cutting. An effective vacuum cleaner can be located directly in the housing.

The sole of the tool can be cast or stamped (in inexpensive models). The quality and speed of performing production tasks depend on the density and uniformity of the fit of the sole to the material being processed.

The base support has holes for accommodating rails.

The size of the hole diameter of the lining affects the maximum diameter of the cutter that can be installed on this device.

Distinctive features of a professional class router:

The presence of a whole set of various additional elements for the device.
The presence of metal bushings instead of polymer ones.
The strength of metal sleeves with bearing assemblies. They guarantee the absence of backlash after repeated overheating and cooling.

Professional models are able to actively work for several hours without a break. Simpler devices require a fifteen-minute break after working for a comparable length of time.

The issue of choosing a tool is difficult to overestimate, but you need to learn how to manage it. It is necessary not only to read the user manual, but also watch a video tutorial on how to work with a wood router.

Basics of working on an electric mill

Before starting practical use, like any equipment, the electric cutter needs to be set up. First unscrew the safety nut and remove the clamping collet. Be sure to check that all threaded connections are tightened to the end and that all threaded connections are reliable. Then remove the dense protective grease.

The cutter is inserted into the collet chuck. If necessary, the cartridge is changed to a suitable diameter. The shank is tightened with a special key so that the cutter does not hang out. Then there is the clamping of the spindle.

The position of the cutter is fixed and the required depth of milling is set with the help of the limiter regulator. The correct speed of the device is determined based on the data of the table of correspondences between the parameters of the material and the size of the cutter. Turn on the device with the "Start" button and make a control cut.

Before real work, you need to check what stroke of the router, the value of the spindle speed and select the depth of penetration of the drill. This is done in draft form. If the product undergoes circular processing, then tool should move counterclockwise and away from you when moving on a flat base.

Beginners in carpentry work often make a common mistake: they change the speed of movement of the device with a figured processing contour. In this case, the machine overheats and burns appear on the workpiece.

Before working with a wood router, it is advisable to read application lessons in good sources.

Grooving

If the groove starts from the very edge, then the cutter should hang over the edge of the part. Then the required depth is set and the tool is started. When the edge is completely processed, the latch is loosened. The cutter is raised and the tool is switched off.

A blind groove is made in the same way, except that the cutting does not start from the edge of the part.

When the groove is very deep, it is cut in several passes. With each new pass, a new depth of no more than five millimeters is established. The depth of the last layer should be no more than one and a half millimeters.

End surface treatment

Creating a clean edge is one of the most common types of work with a hand router.

First, a shallow cut is made. The electric cutter moves in the direction of rotation, then in the opposite direction. After this action, the correct outlines appear at the end.

Working with Curly Templates

Templates allow you to make copies of parts and are used to create curly edges.

With the help of fasteners, the stop ring of the template is attached to the sole. The thrust ring is a plate that moves along the template and forms the necessary trajectory of the cutter.

decorative trim

Decorative patterns are often made to decorate wooden products. The manual machine perfectly copes with the task of artistic milling. You just need to learn how to properly process a pliable tree - and you can mill.

When working on a pattern, in addition to the router itself, you will need a vice, a chisel and a jigsaw. A wooden blank with a pattern on the surface is firmly fixed, and a special cutting nozzle walks along the contour, removing layer after layer of the blank. Gradually, the pattern becomes voluminous.

If you use a cutter of different diameters, you get an individual ornament.

Details of universal hand routers are described in the work of Jackson Day "Working with routers".

It is beautiful when the interior is decorated with paintings made on wood. The carved paintings depicting various stories are impressive in their appearance. You yourself can try to work with a tree using special tools.

The master in his work uses not only tools and raw materials. He needs examples for wood carving: photographs, drawings and sketches. According to them, the master, as an artist, creates his compositions.

The master works with various tools: a jigsaw, a milling cutter, a drill, etc. Let's consider how the work is done according to the drawings.

Wood carving: drawings of work with a jigsaw and a milling cutter according to sketches

To get started, prepare your workplace so that nothing interferes with you, and everything you need is at hand. Take care of good lighting and a comfortable working surface height:

1) Select the material with which you will work. Alder is good for working with a jigsaw. The surface of the workpiece must be smooth and without knots.

2) You can come up with a drawing yourself that you will embody on a tree. You can use the suggested sketches:

3) Transfer the desired pattern to the tree. This can be done using calque. Put it on the workpiece, on top - a sheet with a sketch, and circle all the lines with a pencil. So that the drawing on the workpiece does not smear and does not spoil the whole work, walk along the lines with varnish.

4) Prepare the jigsaw for work. Tighten the tool blade moderately. If the tension is too loose or too tight, the fabric may break.

5) Holding the tool perpendicular to the product, start cutting the pattern along the contour. If the sketch suggests narrow holes, an awl will help you complete them. It is necessary to pierce the hole and cut out the necessary part with the saw itself.

6) After cutting is completed, sand the workpiece, varnish or paint.

Artistic milling

Milling of wooden surfaces in order to make decorated elements is carried out with V-shaped and filler cutters. The master must work well with the tool, be familiar with its technical features.

The milling cutter can perform both contour and through threads. When working with this tool, it is necessary to monitor the implementation of the symmetry of the work. To do this, on the transferred sketch, divide the parts into small segments. These segments must be performed sequentially and symmetrically.

How a slotted thread is made

The work in which the background is completely cut out on a wooden blank is a through carving. Such products are made to decorate the facades of houses, windows. They are also used as elements for furniture or simply as decoration.

You can make a through carving with a knife and a chisel, but it will take quite a long time. To make the process of working with wood less time-consuming, use a jigsaw or hand router.

So that you can accurately complete the drawing, transfer it with carbon paper to the workpiece. Then you can gradually cut out unnecessary details. To make the products look neater, round the edges.

When making wooden products with openwork carving, choose a pattern in accordance with its purpose. After all, a pattern designed to decorate the facade of a house and made with small curls will be inconspicuous. A box with various small details will look spectacular. Also, the railing of the stairs will look good if you make them large details. When making them, it is better to use a milling machine.

In the presence of a milling machine, work on inserting loops, forming complex holes, recesses, woodcarving, etc. is really simplified. But this does not mean at all that it is necessary to have professional and expensive equipment: it is enough to have a simple manual device.

The only thing you need is to be able to handle wood and use power tools. In addition, you need to have a desire, otherwise there will never be a result without it. Those who have no desire to work simply buy furniture or hire craftsmen to, for example, install a new door and embed locks. Any work, especially with a power tool, requires certain knowledge, and especially safety precautions.

The milling device is intended for processing both wood and metal. With its help, it is possible to form recesses or holes of any configuration. This greatly simplifies tasks such as tapping hinges and tapping locks. To do this with a chisel and an electric drill is not so easy, and it takes a lot of time.

There are stationary milling devices and portable (manual). Manual electric cutters are considered universal devices, with the help of which, in the presence of nozzles, it is possible to perform operations for various purposes, it is enough just to change the position of the part relative to the device or vice versa.

Stationary devices are used in factories or factories where mass production of wood or metal products is established. Under such conditions, the cutting nozzle is stationary, and the workpiece moves along the desired path. When using a hand tool, on the contrary, the part is fixed motionless and only then it is processed, although there are parts that require fixing a hand tool. This is provided for in the design, therefore, it is considered more universal. This is especially true when you need to process a large number of parts, and it is not possible to use a stationary machine.

Homemade milling machine - a horizontal platform with a hole in the center, from below to which a manual fixture is attached.

There are many types of milling machines, but for use at home or for starting a business, universal models are more suitable. As a rule, they are equipped with a set of cutters and various devices for performing various kinds of operations. The only thing is that with a manual router, simple operations can take much more time than with a stationary machine.

With the manual milling device it is possible to:

Make grooves or recesses of arbitrary shape (curly, rectangular, combined).
Drill through and non-through holes.
Process ends and edges of any configuration.
Cut out complex shapes.
Carry out drawings or patterns on the surface of parts.
Make a copy of the details, if necessary.

Copying parts is one of the functions of any electric milling machine.

The presence of such functions makes it possible to simplify the production of the same type of furniture or the production of identical parts that are not related to the production of furniture. This is one of the main advantages of this tool. As a rule, for the production of the same type of parts, it is necessary to install copy machines that are designed to perform only one operation, which is not always profitable, especially in small enterprises.

Getting Started and Caring for the Instrument

To understand how this device works, you should familiarize yourself with its main parts and their purpose.

Composition and purpose of the main nodes

The manual milling fixture consists of a metal case and a motor, which is located in the same case. A shaft protrudes from the body, on which various collets are put on, serving as adapters. They allow you to install cutters of various sizes. A cutter is inserted directly into the collet, which is fixed with a special bolt or button, which is provided on some models.

The main elements of a manual milling device and their purpose.

The design of the milling fixture provides a metal platform, which has a rigid connection with the body. It is attached to the body with two rods. From outside the plate has the smooth covering providing smoothness of the movement in the course of work.

The manual milling fixture has some characteristics that can be adjusted:

Due to the handle and scale setting the depth of milling. Adjustment is carried out in increments of 1/10 mm.
By adjusting the speed of rotation of the cutter.

At the initial stages, when the tool is mastered, it is better to try to work at low or medium speeds. Although you should always remember that the higher the speed, the better the work. Especially when it comes to responsible, visible areas that cannot be masked.

In addition to these levers, there is also a button for turning the product on and off, as well as a lock button. These elements are considered the main ones that ensure the quality and safety of work. There is also a parallel stop, which contributes to ease of use. It can be rigidly fixed or with the ability to adjust the shift of the working area, in the direction from the center.

Caring for your handheld router

Usually, a factory product falls into the hands of a person tested and lubricated, so no additional measures should be taken. Only in the process of its operation it is necessary to monitor its cleanliness and serviceability. At the same time, it should be regularly cleaned of dust and change the lubricant, if the passport says so. Especially lubrication is needed for moving parts. Alternatively, you can use aerosol lubricants, but you can get by with the usual ones, such as Litol. The use of thick lubricants is not recommended, as chips and dust stick to them. If aerosol lubricants are used, then this factor can be eliminated.

Lubrication also requires a sole - a smooth part of the body. Regular lubrication will ensure the desired smoothness of movement.

Despite this, the purchased item should definitely be checked for build quality and the presence of lubrication.

Unfortunately, not all manufacturers, and especially domestic ones, care about build quality. There are cases when, after the first hours of operation, screws or screws are unscrewed from the product, as they were not tightened properly.

Rotation speed adjustment

The operation of any tool is associated with certain conditions related, first of all, to the nature of the material being processed. It can be plywood, composite material or ordinary wood. Depending on this, the rotation speed on the electrical appliance is set. As a rule, the technical data sheet always indicates the operating parameters of the device, depending on the technical characteristics and characteristics of the surfaces being processed, as well as the cutters used.

Cutter fixation

The first thing the work begins with is the installation and fixing of the cutter. At the same time, one should adhere to the basic rule - all work is carried out with the cord removed from the outlet.

The cutter is set according to certain marks, and if they are absent, then to a depth not less than ¾ of the length of the cutter itself. How to install the cutter on a specific model, you can learn from the instructions, which must be present in the technical documents for the device. The fact is that each model can have its own design features and it is not possible to talk about this in the article.

Installing the cutter on the device before starting work.

There are models both simple and more "advanced", as they say. Some models have a shaft rotation lock button, which makes it easier to install the cutter. Some, especially expensive models, are equipped with ratchets. So it’s impossible to describe specifically the process of installing the cutter, and it doesn’t make sense, since everyone who is familiar with the operation of such devices will figure it out at the moment.

Milling depth adjustment

Each model has its own maximum cutting depth. At the same time, it is not always the maximum depth that is required, but a certain depth, which is set before work. Even if the maximum depth is required, then, in order not to overload the device, the milling process is divided into several stages, changing the milling depth in steps. For adjustment, special stops are provided - limiters. Structurally, they are made in the form of a disk located under the bar, on which stops of various lengths are fixed. The number of such legs can be from three to seven, and this does not mean that the more of them, the better. It is better if it is possible to adjust each of the legs, even if their number is minimal. To fix this stop in the optimal position, you should use the lock, in the form of a flag.

The milling depth adjustment process is as follows:

Thus, the workpiece is milled to a predetermined depth.

On high-quality expensive models, there is a wheel for fine-tuning the depth of milling.

With this wheel, you can more accurately set the depth without violating the previous setting.

This wheel (green in the photo above) allows you to adjust the depth in a small way.

Cutters for manual milling tools

A milling cutter is a cutting tool that can have an intricately shaped cutting edge. As a rule, all cutters are designed for rotational movements, therefore they have a cylindrical shape. The shank of the cutter, which is clamped in the collet, has the same shape. Some cutters are equipped with a thrust roller, so that the distance between the cutting surface and the workpiece remains constant.

Milling cutters are made only from high-quality metals and their alloys. If you want to process soft woods, then HSS cutters will fit, and if you need to process hard wood, then it is better to use cutters from harder HM grades.

Each cutter has its own technical characteristics, which provide it with high-quality and long work. The main indicator is the maximum speed of its rotation, which should never be overestimated, otherwise its breakdown is inevitable. If the cutter is dull, then you should not try to sharpen it yourself. Sharpening of cutters is carried out on special, expensive equipment. After all, it is necessary not only to sharpen the cutter, but also to maintain its shape, which is no less important. Therefore, if the cutter, for some reason, has become dull, then it will be cheaper to buy a new one.

The most popular cutters

There are cutters that are used in the work more often than others. For example:

Groove molds are designed to create recesses in an arbitrary place on the workpiece.

There are simple cutters, monolithic, made from a single piece of metal, and there are type-setting. Type-setting cutters consist of a shank, which serves as the basis for a set of cutting elements. By selecting cutting planes and installing them on the shank, using washers of various thicknesses, it is possible to form an arbitrary relief on the surface of the workpiece.

A type-setting cutter is a set of cutting surfaces and washers, which allows you to assemble the cutter of the desired shape.

In fact, there are a lot of cutters and this is only a small fraction of what is produced. All cutters differ in shank diameter, cutting surface diameter, cutting height, knife position, etc. As for manual milling equipment, it is enough to have a set of five most popular milling cutters. If necessary, they can be purchased at any time.

Rules for working with manual milling tools

Working with power tools requires special rules, especially when there are rapidly rotating elements. In addition, as a result of the work, chips are formed, which scatter in all directions. Despite the fact that most models are equipped with a protective shield, this does not fully protect against the flow of chips. Therefore, it is better to work with such a tool in protective glasses.

The photo shows a model where a vacuum cleaner is connected to remove chips.

General requirements

If you fulfill the basic requirements for safe work with an electric hand router, then the end result will please you with the quality of work and a safe outcome. Here are the conditions:

The requirements are not very difficult and quite feasible, and ignoring them means putting yourself in danger. And one more thing, no less important, is the ability to hold a milling tool in your hands and feel how it works. If serious vibrations are felt, then you need to stop and analyze the reasons. It is possible that the cutter is dull or a knot is caught. Sometimes it is necessary to correctly set the speed of rotation of the cutter. Here you can experiment: either add speed or reduce it.

Edge Processing: Using Templates

Processing the edge of a wooden board is best done on a thickness gauge. If this is not possible, then you can use a manual router, although this will take some time. These works are carried out both without a template and with a template. If there are no skills or there are very few of them, then it is better to use a template. For processing edges, straight edge cutters are used, both with one bearing at the end of the cutting part, and with a bearing at the beginning (see photo).

Edge cutters.

For the template, you can take an already processed board or another, even object. Moreover, the length of the template must be greater than the length of the workpiece, both at the beginning and at the end of the workpiece being processed. This will avoid unevenness at the beginning of the edge and at its end. The most important thing here is that the template or object acting as a template has a smooth and even surface. In addition, its thickness should not be greater than the gap between the bearing and the cutting part.

The width of the part is less than the length of the cutting part

At the same time, the longer the cutting part, the more difficult it is to work with the tool, since more effort is required. In this regard, it is better to start work with cutters that have an average length of the cutting part. The working principle for edge processing is as follows:

The template is attached so that it is at the desired height and has a flat horizontal surface.
The template is firmly mounted to a table or other surface.
The cutter with a roller is installed so that the roller moves along the template, and the cutter (cutting part) along the workpiece. To do this, perform all the necessary manipulations with the template, workpiece and tool.
The cutter is set in working position and clamped.
After that, the tool turns on and moves along the template. In this case, it is necessary to determine the speed of movement, which is determined by the depth of processing.
The milling unit can be both pushed and pulled: as it is convenient for anyone.

After the first pass, you should stop and evaluate the quality of work. If necessary, another pass can be made by adjusting the position of the tool. If the quality is satisfactory, then the clamps are removed, freeing the workpiece.

With this approach, it is possible to remove a quarter along the edge or in some of its parts. This is done by setting the cutting edge so that it goes to the required depth into the part.

If you replace the cutter with a figured one and shift the guide, as well as use the stop, you can actually apply a longitudinal pattern to the part (in the photo below).

Drawing a longitudinal figured pattern on the workpiece.

If you use a similar milling technique (with a template), you can easily master the technique of working with wood in general. After some time, you can abandon the templates, as their installation takes a lot of useful time.

How to make a smooth edge without a template: experience is indispensable here.

The width of the part is greater than the length of the cutting part

Quite often, the thickness of the workpiece is greater than the length of the cutting part of the cutter. In this case, proceed as follows:

After the first pass, the template is removed and another pass is made. In this case, the already processed part will serve as a template. To do this, the bearing is guided over the machined surface. If the cutting part was again not enough, then you will have to make another pass.
For final processing, you should take a cutter with a bearing at the end, and the workpiece must be turned upside down, after which it is fixed with clamps. As a result, the bearing will move over the machined surface. This approach allows processing thick parts.

The bearing is guided over the machined surface while the cutting edge machine the rest of the workpiece.

In order to master the work of a manual milling tool, you will need a lot of rough workpieces, which you do not mind throwing away later. Nobody got it right the first time. For something to work out, you need to train hard.

Obtaining various curly edges

If a curly edge is required, which is most likely to be necessary, then first pay attention to the condition of this edge. If it is uneven, then it will have to be leveled and only then proceed to the formation of a curly edge, choosing the appropriate cutter.

Rounded edge.

It is necessary to prepare the surface so that the cutter does not copy the curvature along which the roller will move. In this case, a sequence of actions is needed, otherwise a positive result will not work.
