Homemade drilling machine from a drill with your own hands. Stand for diamond drilling Stand for drilling machines

Drilling is one of the most common technological operations in carpentry, so every craftsman knows how important it is to make a hole quickly, and most importantly, as even and clean as possible. When there is a drilling machine at hand, then drilling a hole evenly and quickly is not a problem. And vice versa - when it is not there, then the quality of drilling long holes can be difficult. In this article, we will offer one of the options for a drilling machine from a conventional household electric drill or.

Introduction

Drilling a thin workpiece is not a problem - even if the drill is not perpendicular to the drilling plane, then it will not be easy to visually notice that the hole is not even, therefore, as a rule, the master will be satisfied with the result. In such cases, you can drill "by eye". When the depth of the hole is large, then even with a slight deviation from the perpendicular, the "curvature" of the hole will be noticeable. For such cases, it is necessary to use special devices, and preferably a drilling machine. Therefore, this time we will try to make a home-made machine from a drill or a screwdriver.

original idea

This design is very versatile, since its base part (base and spindle box) is the working part of several other devices described in the following articles:

In these articles there are photos and videos of do-it-yourself machines.

Thus, a part of the design of the described machine can be used for the manufacture and subsequent assembly of three more additional devices. If necessary, having all the components, you can assemble the devices you need at the moment at your discretion.

Preparation for work

Before starting work, you need to think over the sequence of all technological operations in the manufacture of a home-made machine, plan the manufacturing technology, determine the future materials and tools that will be needed in the process.

Tool

To make a machine from a drill or you will need the following tool:

  1. or .
  2. Electric jigsaw.
  3. Angle grinder (angle grinder or simply "grinder").
  4. Drill or .
  5. Grinding machine.
  6. Various hand tools: a hammer, a screwdriver, clamps, a crown on a tree (or simply a “crown”), a square, a marking pencil, etc.

Material and accessories

To make a machine with your own hands, you will need the following materials and components:

  1. 15 mm.
  2. Board pine, massif;
  3. Furniture guides for drawers;
  4. Sleeve;
  5. Furniture futorka;
  6. wing nut;
  7. Fasteners: M6 bolt, self-tapping screws of various lengths.

Main structural elements

The design of the drilling machine consists of the following main elements:

  1. Base:
    • Vertical frame;
    • Spindle box;
    • Platform (horizontal support);
  2. Drilling table;
  3. Drill mount (), used as an electric motor and spindle;
  4. drill();
  5. Spring mechanism and drill feed handle.

Drilling machine manufacturing

To describe the whole process of making a homemade drilling machine, we will break it down into stages by structural elements, attach a photo with comments, and place a video below.

Base

vertical frame

Everything starts from the foundation. To assemble a vertical frame, it is necessary to take two types of bars, two of each size, made of pine or birch with a section of 30 x 40 mm and a length of 60 mm.

We fasten them in pairs among themselves in pairs, where one face is flush, and the other plane is offset. It is better to coat the joint plane with wood glue.

Spindle box base

For the manufacture of the spindle box (moving part of the machine), sliding (rolling) elements are necessary. For this purpose, furniture guides for drawers will be used.

It is necessary to cut 4 guides with a length of 120 mm, and also make stoppers at the ends to prevent accidental exit from each other.

To make the base, you need to use or make three blanks with dimensions:

  • 140 x 155 mm - 1 pc.
  • 155 x 55 mm - 2 pcs.

Then you need to install furniture guides on them.

And assemble the spindle box itself into a "U-shaped" construct.

If the installation was carried out correctly and evenly - without distortions, then the spindle box should move freely along the frame, without clamps.

Platform (horizontal support)

To make a platform (horizontal support), we need to make two blanks:

  • 260 x 240 mm
  • 50 x 240 mm

drilling table

For the manufacture of a drilling table, 4 blanks are required.

The size Qty Description
260 x 240 mm 1 PC tabletop
260 x 60 mm 1 PC Vertical bar of the table
Rectangular triangle Legs: 60 x 60 2 pcs

Since great efforts are possible on the table, it must be made strong enough, so additional strength elements will be required - these are corner stops. There are two of them and they must be installed at the corner of the plank and countertop.

Fixation of the drilling table on the frame is carried out with the help of a bolt, which is pressed with a nut from the reverse side. To install the bolt, you need to press the wing nut into the guides.

After that, you can install the drilling table on the frame by tightening it with a nut with a handle made of.

drill mount

The manufacture of the drill mount begins with the fact that two sheets are glued together and one blank is made with a size of 165 x 85 mm. This is a very important structural element and will need additional strength, so you need to glue two layers.

The drill will be fastened by clamping it in the seat of the front handle, and since it differs for different models, you need to decide on the model and, accordingly, the diameter of the bore for the tool that will be used in this machine. We drill a landing hole for a drill.

The first installation of the drill mount should not be strong, you only need to “bait” the part, since in the future there will be a perpendicular adjustment and, most likely, an adjustment of the installation position will be required. Installation is carried out with a pair of self-tapping screws on the back of the spindle box.

After alignment, it is necessary to more thoroughly fix the attachment of the drill to the spindle box (an additional 4 self-tapping screws), and also install an additional angle stop.

Spring mechanism and drill feed handle

In the future, we will need to install the drill feed handle, so the axis of its rotation will be a pre-installed futorka at the end of the upper spring mounting bracket.

Installing the handle on the machine is not a difficult task - one end of the handle must be fixed with a screw on the upper spring mounting bracket, and the end of the metal rod is attached with a screw to the drill mount.

Now it remains only to drill a hole in the drilling table so that during drilling operations the tool passes through the workpiece, while drilling will be complete and there will be no unnecessary chips on the surface of the workpiece.

Conclusion

Outcome

We made a drilling machine from a drill with our own hands, attached a photo of all technological operations! If you follow all the instructions described above, you will get an indispensable tool that will rightfully take its rightful place in your workshop.

Machine dimensions

Here is a table with the overall dimensions of a homemade drilling machine from:

Blank drawings

Here are drawings with the dimensions of all the details of the homemade drilling machine described above.

Video on which this material was made:

The advantage of the device are as follows:

  1. Cheapness - costs an order of magnitude or two less than industrial (from the store).
  2. Availability of parts - everything can be used in the design, from a small bar to parts from old machines and cars.
  3. A variety of designs in popular publications and on the World Wide Web.
  4. The opportunity for creativity is to create your own reliable multi-functional drill machine that will surpass all published models.

Disadvantages of devices:

  1. When assembling many published models, parts made on machines or components of old units (machines) are needed. This raises the cost of production.
  2. Backlash of parts due to loose mounting and fitting.
  3. A tripod for a drill makes it impossible to perform a number of other jobs (for example, drilling at an angle, etc.).

Universal machine stand

This device is designed to perform various kinds of drilling, turning and other specialized work that the motor and gearbox of the drill can handle. If the tool is powerful, then it can do all kinds of work.

The presented device, if it is intended only for drilling, is made (its main parts) of wood. In the case of making a universal rack, make it from iron or steel plates. The device consists of the following main units:

  1. Bed - serves as the main supporting element of the entire machine.
  2. Rack - designed to secure the carriage with a drill and allows you to move it with a handle and additional elements.
  3. Handle - serves to move the carriage along the longitudinal axis of the rack, which ensures the supply of a rotating tool to the part.
  4. Additional nodes - designed to expand the capabilities of the rack and give it new qualities.

This machine is perhaps the easiest to install and set up, and additional nodes allow you to turn it into a universal device that will appeal to many DIY craftsmen. Consider the main parts of the machine.

DIY drill stand

This node represents a slab of 10 mm (or more) of metal or 20 mm (or more)

tree. The greater the power of the tool (drill), the more massive the base should be. The dimensions of the bed depend on the work performed and may vary:

  • for vertical drilling - 500x500 mm;
  • for other works - 1000x500 mm.

But these dimensions are not final and can be changed according to your requests.

The cheapest and easiest to repeat bed is cut from a 20-40 mm piece of wood or made from 10-20 mm steel. The main rack is fixed on it (exposed vertically) and a support from segments of the same thickness. Both parts are screwed with screws or screws to each other and from below (through the frame).

Advice: For reliability, you should connect the rack and support to each other using metal corners.

Drill stand for drill

It is made of 20-40 mm board or 10-20 mm steel plate. Its length is 50-75 cm and depends on the size of the drill used, and its width is 20 cm. A mechanism for moving the drill along the longitudinal axis with a device for fixing the drill is fixed on the stand.

The assembly order of the rack is as follows:

  • a support is strengthened on the bed;
  • a vertical stand is screwed to the base, which is then screwed to the support;
  • on the vertical, the bases of two guides (telescopic furniture) are strengthened, for example, from a table;
  • further, a carriage with a device for fixing the drill is screwed to the movable part of the guides.

Advice: When choosing guides, check that there is no lateral play.

The length of the carriage also depends on the dimensions of the drill and is 50-100 cm. It is made of a board or plate of steel of the same thickness and width as the stand. The carriage can be made in two versions:

№ 1. The drill is secured with clamps.

The figure shows the fastening of a conventional email. drills. The board is drilled, the clamps are threaded into the holes. Clamps are tightened with a suitable screwdriver.

№ 2. The drill is fixed on a special block.

The block is a plate screwed perpendicular to the axis of the carriage and reinforced with metal corners. A hole was drilled in the block 0.5 mm less than the diameter of the "front" of the drill and a slot was made for secure fixation of the tool.

The hole is drilled with a special nozzle (cylindrical) or as follows:

  • measure the diameter of the tool and draw a circle;
  • inside the circle (closer to the line) drill a series of holes;
  • cut through the remaining partitions with a file, knife or saw;
  • with a semicircular or round file, the circle is leveled, bringing it to the required caliber.

Movement mechanism

The main elements of this node:

  • Handle - serves to feed the drill towards the workpiece.
  • Spring - designed to return the carriage to its original state.

The movement mechanism can be made in two versions:

  1. The spring is located directly at the handle.
  2. Two springs are located at the bottom - in the grooves of the carriage guides.
  • 2 metal plates are screwed to the main rack from one end, between which an axis for the handle is inserted (you can use an M8-M12 screw).
  • Plates are also screwed on the other edge, between which a spring is installed. To limit the possibility of its dismounting to the side, pins are used, one of which is installed on the stand, and the second on the handle, which moves between the plates.
  • A longitudinal groove is made in the handle for the normal operation of the mechanism.
  • A pin or axle is fixed on the carriage to ensure vertical movement.

2 Option 2.

And in this case, side plates and the central pin of the handle are used, but the springs are located in the grooves of the furniture guides, which are being slightly modified. Ordinary metal corners are inserted and screwed into the grooves to prevent the springs from slipping deep into the guides.

The operation of the mechanism is simple. When you press the handle (lever), the carriage with the drill moves down, providing drilling of the part. During the working stroke of the carriage, the springs are compressed, storing energy. When the lever is released, the energy of the springs is directed back, and the carriage goes vertically upwards.

Additional nodes

By modifying the rack with a simple knot, you can drill holes at an angle and perform simple turning and milling work on wood.

Milling work

To perform small milling work, it is necessary that the part move horizontally. To ensure the feed, a second same rack is used, which is fixed horizontally on the frame. Only instead of a drill, a vise should be fixed on it.

The distance from the edge of the part to the groove to be cut is limited by the gap from the drill to the vertical guides. For horizontal feed, you can use a lever (using a handle) system, but to avoid difficulties, find the feed mechanism of the machine table (screw).

Drilling holes at an angle and turning work

To perform these operations, it is necessary to supplement the rack with a rotary mechanism, which is an additional plate (AP) with holes located along the arc. All parts of the feed mechanism and the carriage are placed on this additional plate, which rotates on an axis fixed to the main rack.

The main angles of inclined holes are 30 o, 45 o, 60 o. The turning mechanism can be done like this:

  • first, a hole for the axis is drilled on the rack and in the turntable;
  • further, measuring the angles with a protractor or some other measuring device, drill holes in a circle on the DP;
  • then combine the axial holes of both plates and fix them with a screw;
  • after that, 3 holes are drilled through the DP on the rack, as shown in the figure.

The additional plate is rotated to the desired angle and fixed to the back of the rack with three pins or screws with nuts (the latter is preferable).

Turning work is carried out by turning the additional plate horizontally. Due to the small size of the drill chuck, large-caliber parts cannot be processed on it.

Drilling work is not particularly difficult and often does not require other equipment than a conventional drill. Therefore, in home workshops, a drilling machine may not be available. However, if you have a DIY bench drill press, you can breathe a sigh of relief, as part of your worries will resolve itself.

Purpose of the drilling machine

Sometimes there are situations when an electric or hand drill is not able to provide the desired parameters of the hole being drilled. Often in amateur radio practice, it is necessary to manufacture printed circuit boards, where many holes should be drilled, which have a small diameter. Drilling holes with a diameter of 0.5-1 mm with a hand or electric drill or a large drilling machine is inconvenient, and the drill may break.

Buying industrial drilling machines is not always economically feasible, and then you can make a homemade drilling machine. Many people choose mini drilling machines, because, despite the apparent complexity of the design, they are actually very simple equipment and consist of four parts.

A self-made drilling machine is designed for drilling through and blind holes in solid material, for example, reaming, reaming, countersinking, cutting discs from sheet materials and cutting internal threads. Drilling and milling machines can perform milling, surface grinding, bevel milling and horizontal milling.

To perform the above operations, a countersink, drill, tap, reamer and other tools are used. Using special fixtures and additional tools, you can cut a hole with a large diameter, bore a hole and accurately lap the hole.

Types of drilling machines

Drilling machines are of the following types: single and multi-spindle semi-automatic, vertical drilling, jig boring, radial drilling, horizontal boring, horizontal boring, diamond boring. Models are designated by numbers and letters. The first digit indicates the group to which the machine is assigned, the second - the type of machine, the third and fourth - the dimensions of the machine or the dimensions of the workpiece being processed.

The letter that comes after the first digit means that a certain model of the drilling machine is upgraded. If the letter is located at the end, then it should be understood that, on the basis of the main model, a drilling machine different from it was made. It is possible to distinguish from all drilling machines such main varieties of universal machines: multi- and single-spindle, radial and horizontal drilling.

Depending on the area of ​​​​use, a distinction is made between special and universal drilling equipment. Specialized machines for mass production and large-scale industry have also found wide application, which are manufactured on the basis of universal machines by equipping them with multi-spindle thread-cutting and drilling heads and by automating the work cycle.

Drilling machine design

The drilling machine, like other technological machines, consists of the following components: a transmission mechanism, an engine, controls and a working body. The transmission mechanism is designed to transmit movement from the electric motor to the working body, which is considered to be a drill, which is mounted in a chuck mounted on a spindle - a rotating shaft.

Rotation to the spindle from the electric motor is transmitted by means of a belt drive. By turning the handle, the chuck and drills can be lowered or raised using rack and pinion.

On the front panel of the drilling machine there are buttons for switching off and on the electric motor. The device of the drilling machine is quite simple: the machine is turned on by pressing one of the extreme buttons, depending on the desired direction of rotation of the spindle, you can turn off the machine by pressing the middle red button.

A fixed vertical screw-column is attached to the base of the machine. By turning the handle, you can move the headstock up or down along the screw, the second handle serves to fix it in the required position. Control the depth of blind holes using the provided scale.

Depending on the workpiece material, different drilling speeds are required. To do this, it is customary to set a certain spindle speed by transferring a belt drive belt to pulleys of various diameters. In the workshops of factories, more complex schemes of drilling machines are used than have just been considered.

The principle of the machine

Before drilling with a homemade machine, you need to remove everything superfluous from the desktop. The workpiece with the marked centers of the holes must be fixed in a vise. Then insert a drill of the desired diameter into the chuck and fix it with a special key. To check the correctness of the work performed, the machine is turned on for a while.

If you have correctly installed the drill, when rotating, its tip will not describe a circle. If it is installed with a warp and its beating occurs, then the drilling machine must be turned off and the drill must be fixed according to the instructions of the drilling machine. Then turn the feed handle, lower the drill and set the vise with the workpiece in such a way that the core coincides with the tip of the drill.

Turn on the machine and drill a hole, press the feed handle smoothly, without much effort and jerks. When drilling a through hole, place the workpiece on a wooden block so that the drill does not break and the machine table does not deteriorate.

When drilling a deep hole, take the drill out of the hole from time to time and cool it by dipping it in a bowl of coolant. It is recommended to reduce the pressure on the handle at the end of drilling. After drilling a hole, smoothly turn the feed wheel, raise the spindle to its highest position and turn off the machine.

Drilling machine manufacturing

A drilling machine is easy to make with your own hands. In everyday life, it is beneficial to have fixtures and tools for carpentry and plumbing work on hand. After the obsolescence of many household appliances, many useful spare parts and electric motors remain in the arsenal of the owners, from which, if desired, you can make such useful equipment as a drilling machine.

Drilling machine from a drill

The easiest solution for you will be to assemble a mini drilling machine with your own hands using a drill. The drill weighs a little, so the rack can be made from chipboard, boards or sheet metal. For comfortable work on such a home-made machine, it is necessary that it turns out to be quite massive to absorb the vibration of the drill and sufficiently stable.

It is important to get a right angle between the holder and the base. Usually, the drill is attached with two clamps (it is better to place a rubber gasket between the clamp and the drill) to the board, which moves along the guides that are fixed on this movable board and on another fixed board. The downward and upward movement of the movable board is controlled by a lever associated with it.

The downward movement of the lever can be limited by a bar supporting the lever in the lower position. A fixed board is attached to a horizontal pipe through a flange. A horizontal pipe through a square is attached to a vertical pipe, which is attached through a flange to the base of the machine (to a thick wide board) or to a workbench.

The height of the bar, which limits the lower position of the lever, is adjusted, which allows you to change the depth of drilling. Make 4 holes in the movable board, which are intended for clamps fixing the drill. On its side, which faces the fixed board, narrow rails are glued, which are lubricated with wax for better glide.

The drill, in addition to clamps, is fixed with two rods that support it from below. Since with such a fastening, the shape of the drill does not strictly ensure the vertical position of the drill, it is necessary to glue a lath to the board to compensate for this.

To ensure the free movement of the drill, the guides must be prepared strictly in the vertical direction. They can be a protrusion of aluminum metal profiles, which are screwed with threaded screws to the boards along the entire length. Having assembled a solid and stable structure, it is necessary to fix the profile guides strictly perpendicular to the plane of the base and parallel to each other.

In the photo of self-made drilling machines, the places of attachment to the movable platform of the drill and the method of mounting the guide profiles are clearly visible. The guides must ensure high-quality pressing of the movable to the fixed board. The main condition for this is the absence of distortions and backlash.

When assembling the lever, remember that you cannot tighten the moving parts; it is customary to use a second nut to lock the nuts. The rail that leads to the movable board from the lever should be rounded at the end. After reducing the pressure forces to automatically raise the drill to the upper position, it is necessary to put the springs on compression or tension.

One end of the spring is attached to the horizontal pipe with a wire, and the other end is attached to the bottom of the movable board. When the spring is not flexible enough, and a fixed board interferes, then this is done through a rope.

Machine from a motor from a washing machine

The drawing of a drilling machine, which is assembled on the basis of a motor from a washing machine, differs from the one discussed above in the most complex mechanics and the type of electric drive. The asynchronous motor from the old washing machine is heavier and has more vibration. The shaking will be stronger the farther from the rack the engine is located.

Intense vibration provokes inaccurate drilling and breakage of the drill. There are two ways out - to make a powerful frame so that when the drill is lowered, the drive also drops, or the motor is placed motionless closer to the holder stand, then only the working part of the drilling machine will walk.

The second method involves a more complex implementation. Here you need a pulley and a belt that allow you to adjust the speed of rotation. There are many solutions without a belt drive with a drive located against the wall. They are much easier to assemble, but the assembly, which will be discussed below, is characterized by an unconventional approach, and certain applied techniques may be useful.

Vibrations still remain, but they are so minimal that when drilling iron with a 0.7 mm drill, the drill remains intact. At home, high precision in the manufacture of such mechanisms can only be dreamed of, but it is still necessary to strive for maximum fitting of parts. The characteristics of the drilling machine and its performance will depend on this.

The moving part of the machine consists of an axial hexagon, a tube of a suitable size, a clamping ring and two bearings and a tube with an internal thread to secure the chuck. On the hexagon, part of the future transmission system, a pulley is subsequently put on. The tube must first be cut with a grinder along both ends, and make the cuts on top deep enough to ensure a secure grip with the hexagon.

The entrance must be made tight, driven in with a hammer. If donning occurs without much effort, then you need to pick up another tube. Then stuff the compression ring and bearings. The height adjustment system consists of a pipe with cuts and a gear. To make the cuts accurately, you need to roll out the plasticine and drive along it with a gear.

An imprint will appear, which is easy to measure and make the appropriate markup on the adjusting pipe. The length of this ladder should correspond to the maximum height to which the drill can be raised. Press the axle with hexagon and bearings into the slotted tube.

Such a design will go back and forth vertically in the stationary tube of the bed when the gear is scrolling. At the same time, the axis is rotated in a horizontal plane through a belt drive. The bed is made of a metal corner with the help of bolts. The whole structure is attached to the wall.

And finally, remember that the first option for assembling a drilling machine is preferred. The proposed second version of the assembly can be supplemented or improved. However, such a simplified solution deserves attention.

It is not necessary to spend money on a bench drill, because it is not so difficult to make it yourself. To do this, you will need to purchase, manufacture or use used parts. We will walk you through the creation of several designs, and you will be able to choose your own model for assembly.

Almost every owner who builds or renovates his house or apartment, repairs household and garden equipment, and various crafts made of metal and wood has a drill. But for some operations, a drill is not enough: you need special accuracy, you need to drill a hole at a right angle in a thick board, or you just want to make your work easier. This will require a machine that can be made on the basis of various drives, machine parts or household appliances, and other available material.

The type of drive is a fundamental difference in the designs of home-made drilling machines. Some of them are made using a drill, mostly electric, others - using engines, most often from unnecessary household appliances.

Desktop drilling machine from a drill

The most common design can be considered a machine made from a manual or electric drill, which can be made removable, so that it can be used outside the machine, and stationary. In the latter case, the switching device can be transferred to the frame for greater convenience.

Main elements of the machine

The main elements of the machine are:

  • drill;
  • base;
  • rack;
  • drill mount;
  • feed mechanism.

The base or bed can be made from a solid cut of hardwood, furniture board or chipboard. Some prefer a metal plate, channel or brand as a base. The bed must be massive in order to provide stability to the structure and compensate for vibrations during drilling in order to obtain neat and accurate holes. The size of the frame made of wood is at least 600x600x30 mm, from steel sheet - 500x500x15 mm. For greater stability, the base can be made with lugs or bolt holes and fastened to a workbench.

The rack can be made of a bar, round or square in section of a steel pipe. Some masters use the frame of an old photographic enlarger, a substandard school microscope, and other parts that have a suitable configuration, strength and weight as a base and stand.

The drill is fastened with clamps or brackets with a hole in the center. The bracket is more reliable and gives greater accuracy when drilling.

Design features of the drill feed mechanism

The feed mechanism is needed to move the drill vertically along the rack and can be:

  • spring;
  • articulated;
  • screw jack design.

Depending on the type of mechanism adopted, the type and arrangement of the rack will also differ.

The drawings and photos show the main designs of bench drilling machines that can be made from electric and hand drills.

Machine based on the steering rack of a car

The steering rack for a car and a drill are quite massive products, so the bed must also be massive and, preferably, with the ability to fix the machine on a workbench. All elements are welded, as the connection with bolts and screws may not be sufficient.

The bed and the support post are welded from channels or other suitable rolled products, about 5 mm thick. The steering rack is fixed to the rack, which should be 70-80 mm longer than the rack, through the lugs of the steering column.

To make it more convenient to use the machine, the control of the drill is taken out in a separate block.

Video 5. Drilling machine based on the steering rack from Moskvich

The order of assembly of drilling desktop machines:

  • preparation of all elements;
  • fastening the rack to the frame (checking the verticality!);
  • assembly of the movement mechanism;
  • fastening the mechanism to the rack;
  • drill mount (check verticality!).

All fasteners must be made as securely as possible. It is desirable to connect steel one-piece structures by welding. When using any kind of guides, you need to make sure that there is no lateral play during movement.

Advice! To fix the part in which the hole is drilled, the machine can be equipped with a vice.

On sale you can also find ready-made racks for a drill. When buying, you need to pay attention to the mass of the structure and the size of the working surface. Light (up to 3 kg) and inexpensive (up to 1.5 thousand rubles) racks are suitable for making holes in a thin plywood sheet.

Drilling machine using asynchronous motor

If there is no drill on the farm or it is not desirable to use it in the machine, you can make a design based on an asynchronous motor, for example, from an old washing machine. The scheme and manufacturing process of such a machine are quite complex, so it is better to do it by a master with sufficient experience in turning and milling, assembling electrical circuits.

Homemade machines for drilling printed circuit boards

Mini-board drilling machines for radio amateurs also borrow a drive from various low-power devices. At the same time, cutters for cropping photographs are used as levers, soldering irons, collet pencils instead of a cartridge. The drilling site is illuminated with LED flashlights - there are enough opportunities for technical creativity.

Everyone who uses a hand drill knows how difficult it is to keep a strict vertical with your hands. When drilling workpieces of large thickness, there is a risk of breaking the drill. Every time there is a desire to guide the tool along the guide, but there is no such possibility.

The second common task is to drill many holes of the same type in one workpiece. Holding a drill in your hands, doing such work is long and inconvenient.
Since ancient times, locksmith workshops have used drilling machines of various capacities. But their cost for home purchase is too high.

In addition, the home master does not perform drilling on an industrial scale. Therefore, such a purchase will never pay off.

There are factory-made vertical drilling fixtures that can turn a hand drill into a full-fledged drilling machine. Many of them are equipped with coordinate plates and movable vise.

Stand vertical for drilling holes with a drill

This is a really convenient purchase, but the cost of such a machine is comparable to the cost of a drill. Therefore, home craftsmen often make a homemade drilling machine.

The main advantages of the design- cheap and the ability to create a fixture that is perfectly compatible with your hand drill. If there is an unnecessary photographic enlarger, microscope or other mechanism with a vertical feed of the working unit in the house (barn, garage), the task is simplified.

It remains only to adapt the drill to the product. If there is no such bonus, the stand is made from scratch.

What should the guide stand for a hand drill consist of?

stable bed

Preferably with the possibility of installing a vice or other device that holds the workpiece. At home, it is made of thick chipboard, plywood, or textolite. In the center of the axis of the drill being installed, it is necessary to leave a hole with a diameter of a couple of centimeters.

Here the imagination of developers is unlimited. It can be a bar, plywood plate, metal profile or pipe.

The main principle in the manufacture is a strict vertical in relation to the supporting frame. Otherwise, the drill will deviate from the rectilinear movement, spoil the workpiece and break.
