How to make a drilling machine at home. Do-it-yourself drilling machine - we create an individual working tool. Drilling machine from a conventional drill

A do-it-yourself drilling machine can be made at home from an ordinary electric drill or a steering rack.

In the workshops of radio amateurs, mini home-made machines are most often found for the reason that it is expensive to buy industrial units, and it is not difficult to make a device with your own hands.

The idea - how to make a drilling machine (including with the help of a steering rack) comes to mind not only to radio amateurs, but also to people who from time to time need to perform repair work in their homes.

At the same time, special devices or high-strength materials are not required for the manufacture of a micro-aggregate.

At the initial stage, it is necessary to create drawings to facilitate the manufacturing process of the machine.

Drilling unit from a drill

You can assemble a filler mini drilling machine from a drill with your own hands from just four main components. The first thing to do in order to create a filler machine is to choose a bed - the basis for the future.

An electric drill can be used as a rotation mechanism, which is necessary for the filler mini machine to function. Then you need to decide on the feeder and vertical type rack.

Since the drill is light in weight, you should not look for special fixtures and very durable materials for the stand, you can take wooden boards or chipboard.

For the bed, on the contrary, it is necessary to select a more massive material, which will eliminate the appearance of vibration during drilling.

A suitable material in this case is a furniture board with a thickness of 2 cm or more.

The best option when choosing a material for the manufacture of the frame may be the stand of an unnecessary photographic enlarger, but its design will have to be slightly modified.

The accuracy of the drilling process on a homemade mini unit will depend on the quality of the connection between the vertical rack and the bed.

From steel strips, it is necessary to cut two guide bars for moving the block with a drill. Attach these fixtures to the rack with screws.

To securely hold the drill in the manufacture of pads, steel clamps are used.

A rubber gasket is placed between the drill and the block in order to reduce the vibration of the mini drilling machine.

The feed mechanism of the machine is a simple lever with which the block with the drill will move vertically. The mechanical device is equipped with a spring, sufficiently powerful and elastic.

One end of the spring element will rest against the block, the second - against the beam attached to the table.

To achieve the most convenient use of a mini drilling machine, provided that the drill is not planned to be removed from it periodically, it will be possible to completely disassemble the drill switch and mount a separate switch on the frame.

You can consider to the smallest detail how to make an additive desktop drilling unit using an electric drill in the proposed video.

Steering rack for drilling machine

The drilling machine can be made using an upgraded steering rack. Since buying a new steering rack will not be cheap, it is recommended to purchase a used part, preferably from a VAZ 2108.

After purchasing the steering rack, it is necessary to carry out preventive maintenance of the part in order to ensure its smooth running.

Instructions for the manufacture of the bed and its installation:

• The body of the machine is made taking into account the dimensions of the drill and column. The table on which the platform with drilling parts will be fixed must have suitable dimensions, approximately 20x30 cm;
• The structure with which the drill will be fixed is mounted on the steering part at the locations of the mounting bolts;
• The stand for the drilling machine is made of U-shaped steel profile 30x60x30. It is welded to a sheet of metal 2 mm thick. The rack should have a height exceeding the length of the column by 6-7 cm. The stroke for the steering rack from the VAZ 2108 is 210 mm;
• By mounting additional ribs between the two elements, the rigidity of the rack is increased.

For comfortable use of the drilling machine, it is recommended to think over a convenient system for starting and shutting it down.

To supplement the theme will allow thematic video material.

PCB Drilling Machine

To assemble a micro drilling machine for printed circuit boards, you will need the following parts:

• micro motor or high speed motor;
• clamping collet for fixing miniature drills;
• two wooden beams, U-shaped profile, fixing ring for fixing the electric motor;
• mobile platform of the machine for printed circuit boards - is made independently from improvised materials.

When assembling a desktop micro drilling machine for printed circuit boards, it is recommended to pay attention to the fact that the drill is lowered exactly perpendicular to the board.

The video below shows a mini PCB drilling machine.

If the motor is skewed, then when drilling printed circuit boards, the drills will fail. A gap and poor fixation of the motor are not allowed; at high speeds, it can be knocked out of the frame.

How to make a micro machine with your own hands for drilling boards will tell the video material.

Coordinate table design

If in a home-made drilling machine the functions of the coordinate table are performed by the feed mechanism, then the coordinate milling table has a different design.

The coordinate milling table is a manipulator consisting of a certain number of axes. The milling table is intended for movement in several planes of the technological head.

At home, you can make a milling table using linear-type modules made of aluminum profiles.

As a transmission, a gear rack, a reinforced belt or a ball screw element is used.

Numerical control (CNC) and action controllers are needed to control the XY table. Controllers are used to manage technical tasks.

To make a milling table, first make drawings, calculate and select components.

In this case, the calculation made must fit the technical requirements for the use of the machine, including the moving masses, speed, acceleration and positioning accuracy.

The design of the coordinate table can have a lightweight or hardened look, be two or three coordinate. That is why it is recommended to initially decide what the milling table will be needed for.

Two-coordinate table - base with a movable cross. A desktop is mounted on it. The crosspiece must contain hardened adjustable and ground rails.

Stroke stops are also installed to eliminate clearance. The base is fixed on the legs.

You can learn more details about making a coordinate table with your own hands from the proposed video.

Homemade vice for machine tools

If you can’t afford the Soviet vice, and you don’t like Chinese products, then you can make a vice with your own hands in addition to the drilling machine.

To assemble a homemade vise, you must have the following parts on hand:

• screw - thread 20 mm, length - 150 mm, the screw head must have a slot, as sometimes it does not fit the size of the handles, but it is expanded with a file;
• a screw with a ring is used as a handle for tightening;
• studs can be purchased at the store or found in old parts;
• then you need to make a fixed sponge, it can be made of pine wood, and the board is nailed to the countertop;
• for the manufacture of the movable part, a board (20 mm thick, 18 mm wide) is required, the length of the movable jaws must be at least 50 cm.

Holes with a diameter of 21 mm are made in the tree. The diameter of the holes in the studs should be 10 mm. Studs, screws are installed in the finished holes, nuts and bolts are baited.

If the vise will be used to work with short workpieces, then the studs are rearranged in the structure.

The vise is provided with additional holes, which should be located near the clamping screws.

Homemade vise can have different parameters, it all depends on the selected parts.

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 required. For this purpose, furniture guides for drawers will be used.

It is necessary to cut 4 guides 120 mm long, 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.

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.

Video on which this material was made:

On the farm, the home master should have a set of all tools, and therefore this is the unit that will help him further expand his functionality.

Many for drilling various holes in everyday life can be satisfied with a conventional drill, however, the possibilities and tasks of even the simplest drilling equipment are more global.

A desktop drilling machine, in addition to reaming, countersinking and reaming, can also mill (there is a milling unit), as well as grind various surfaces, and also perform a number of other tasks.

Such equipment is especially relevant for radio amateurs, who, with the help of it, can solve a number of their narrowly focused tasks.

Such a unit for a home workshop can be bought at any specialized store, but it costs a lot, and not every master will find extra money to purchase a professional drilling machine, which is shown in the photo below.

Meanwhile, if you wish, you can assemble a home-made drilling machine for drilling wood and metal with your own hands from an ordinary drill.

Of course, you will have to spend personal time on the manufacture of the machine, but the result is worth it.

A desktop home-made drilling machine in a mini version for wood and metal, with all the necessary materials, can be made by every home craftsman.

Drilling a variety of holes in everyday life is carried out, as a rule, with the help of a hand drill, which is in the home workshop of every skilled owner.

Meanwhile, even at home it is not always possible to achieve the desired result through the use of an ordinary drill.

In this case, the question arises of making a mini vertical-horizontal drilling machine for wood and metal with your own hands.

Such a universal unit is simply necessary for those involved in radio electronics for drilling small holes in printed circuit boards, which cannot be done with a hand drill.

In addition, a home-made drilling machine will not interfere and, if necessary, drill through and blind holes in various types of materials.

With it, it is very easy to perform reaming and countersinking, as well as, if necessary, to cut the thread.

If you additionally install a milling unit on it, then the capabilities of the unit will expand even more.

The milling unit will make it possible to perform a variety of simple operations for vertical-horizontal milling of a variety of materials.

A filler mini drilling unit for drilling printed circuit boards can be made from the most ordinary drill, however, to solve more complex tasks, a more structurally complex device, the same milling unit, will be required.

Any professional drilling unit consists of several mandatory elements, which include such as a drill, countersink, tap, and also a reamer.

Do-it-yourself filler mini machine must also contain all these components.

If the drilling machine is assembled according to all the rules with his own hands, then the home master can easily, using a milling unit, in addition to drilling printed circuit boards, cut and bore a hole with the required diameter, grind it precisely, and also perform a number of other specific tasks.

Before proceeding with the assembly of the unit, it is recommended to carefully study the existing types of drilling machines and understand the basic principle of its operation.

The video posted above shows a homemade drilling unit in operation, which can also be used for drilling printed circuit boards.

Species and types

Currently, a huge number of various modifications of drilling equipment are used in industrial enterprises and in everyday life.

Many of them are intended for solving exclusively professional tasks, and are simply not suitable for home use for various reasons.

In the photo below, you can see an industrial drilling machine.

Today you can find spindle machines, semi-automatic machines, vertical drilling, as well as many other types of units.

For domestic use, a filler mini unit is suitable, capable of solving simple tasks.

For example, if the machine is needed mainly for drilling printed circuit boards, then it can be assembled from the most ordinary drill.

Like any other equipment, industrial drilling units have their own special designations and markings, which can be used to determine their type and main purpose.

The most popular devices that are encountered most often are spindle devices, as well as units for radial and horizontal drilling.

Very popular coordinate unit designed for boring workpieces.

All drilling equipment can be safely attributed to the universal type. For a home workshop, it will not be difficult to make a universal-type filler mini-unit with your own hands.

If desired, a home-made coordinate unit can be automated as much as possible and supplemented with various devices, which will only add to its overall functionality.

Depending on the functional purpose, each drilling machine, including the coordinate one, consists of a certain number of elements.

Any unit of this type, including a home-made one, necessarily consists of a frame, a steering rack, and an engine. The photo below shows a homemade filler mini drilling unit.

Design features

The drilling machine is a type of industrial equipment designed to solve narrowly focused tasks.

It must necessarily include a transmission mechanism, control and working bodies, as well as a sufficiently powerful electric motor.

Each mechanism included in this equipment has its own purpose, which determines its functional tasks.

So, the transmission mechanism is intended mainly to transfer the necessary movement to the working bodies, directly from the installed engine.

In this case, the working body is a drill, which is attached to a chuck, which in turn is connected to a spindle and a rotating shaft.

In the machine of this type, the rotation from the engine to the working bodies is transmitted by means of a belt drive. In order for the drill to be in a given position, a rack and pinion gear is used, associated with a special handle.

It is imperative that such a machine, even if it is assembled from a drill, must have buttons in an accessible place that are responsible for turning it on and off.

Machines of this type have a fairly simple device, moreover, they can perform a huge number of very different functions and solve many narrowly focused tasks.

When assembling such a machine with your own hands, for a higher accuracy of work, it is recommended to place a special scale directly on its moving part.

It will help control the depth of blind holes. It is also best to make such a machine on which it will be possible to change the rotation speed of the cartridge, depending on the tasks performed.

The desktop should be made exclusively from a solid metal plate, rigidly fixed to the base.

The video below shows a homemade drilling unit, with which you can drill printed circuit boards and more.

Principle of operation

A drilling machine assembled according to all the rules will be able to successfully drill holes of various diameters, including micro ones, with great accuracy, which is especially important for printed circuit boards.

Despite the apparent simplicity, you need to work on it in compliance with generally accepted rules.

So, just before you start work, you need to check the availability of power in the network, the integrity of all equipment, and also clear the desktop of everything superfluous.

There must be a vise on the table itself, with which it will be possible to conveniently fix the workpiece.

Before starting work on the part, it is necessary to mark the future hole in accordance with the drawing, then place it in a vise on the table and firmly clamp it.

Next, a drill is fixed in the chuck and a test run is made. Homemade vise for the drilling machine, which are used at work, must have certain dimensions, including in order to work with micro holes.

During the test start of the machine, it is necessary to check the rotation of the drill and make sure that it rotates without describing the circle.

This is especially true when drilling micro holes. At the time of drilling, the handle should be actuated with smooth movements, while the drill must be periodically cooled.

Drilling micro holes should be done with extreme precision, for which use coordinate indicators.

Upon completion of the work, the drilling machine should be turned off, open the vise and remove the finished workpiece. The video above shows how the machine works.

How to assemble?

The easiest option to assemble a filler drilling machine without a steering rack is to use an ordinary drill.

In this case, it is necessary to make the table massive in order to minimize the vibration of the machine during operation. A stand for a drill can be made from both chipboard and metal corners.

First you need to connect the stand and the table to each other at a right angle, while the drill should be fixed with clamps. A driving mechanism should also be provided.

A vise must be attached directly to the table, in addition, the on and off button must be in a visible place. In the video below you can see the manufacture of a machine from a drill without a steering rack.

You can assemble a more complex and functional machine with a steering rack for drilling from the engine from the washing machine. This device will allow, among other things, to drill micro holes with great accuracy.

In this case, the desktop should be even more massive, since the vibration during operation will be quite strong.

Particular attention should be paid to the moving part of the unit, and for these purposes it is better to use ready-made drawings. It is recommended to connect the engine with the cartridge using a belt drive.

If all actions are performed correctly, then such a machine will be able to drill even micro holes with great accuracy.

The video below shows a homemade machine powered by a washing machine engine, which will be very useful in your workshop.

In a wide range of plumbing work, drilling is perhaps the simplest and most accessible operation for everyone. As a rule, in production, drilling work is carried out using various drilling machines.

Depending on the tasks performed, these can be the most common single-spindle units, and multifunctional multi-spindle machines with numerical control.

Homemade desktop drilling machines

However, we will not be distracted by the description of all kinds of industrial drilling machines, especially since the home master, for whom this article is intended, will hardly be interested in the subtleties of the design of a universal vertical drilling and boring machine. But the design of the simplest home-made drilling machine, which can be assembled from improvised material at home, will interest any "handy" master.

To perform drilling work at home, in most cases, it is enough to have a conventional electric drill.

However, when performing work that requires high accuracy or drilling many holes of small diameter, which is especially important for radio amateurs in the manufacture of printed circuit boards, a drilling machine will be required, since an electric drill will not provide either the required accuracy or the quality of drilling.

Of course, today in any specialized store many models of various machines are sold, including drilling machines, designed for use in home workshops. However, their cost is considerable, and not everyone can afford such a purchase, especially since with certain skills and desire, the simplest drilling machine can be made independently.

The most common types of homemade drilling machines are:

• Drilling machines based on an electric drill
• Drilling machines based on an asynchronous motor from household electrical appliances

Consider in general terms the manufacturing technology of each of these machines.

Drilling machine based on an electric drill

Due to the ease of manufacture, drilling machines based on an electric drill can most often be found in home workshops.

The weight of the electric drill is small, so for the manufacture of a vertical stand you will not need any particularly strong materials, it can even be made from boards or chipboard.

The design of the drilling machine consists of 4 main elements:

1. Base (bed)
2. Vertical stand or beam
3. Feed mechanism
4. Electric drill

The choice of the base of the machine, the frame, should be taken very seriously. The more massive it is, the less vibration will be felt during operation. If your farm has an old photographic enlarger for developing pictures, it can be adapted after a little refinement as a base with a stand. In the event that you didn’t find anything that could be adapted as a bed with a stand, this element can be made from a furniture plate with a thickness of at least 20 mm.

When attaching the rack to the frame, it is extremely important to get a right angle, since the accuracy and quality of drilling will depend on this. With the help of screws, two guides, cut out of metal strips, should be fixed to the rack, along which the block moves up and down, to which the drill is attached. The block should be made in such a way that the drill can be tightly clamped with metal clamps.

To reduce vibration, a rubber gasket can be installed between the body of the electric drill and the shoe. The vertical movement of the block with a drill is carried out using a lever. To ensure the convenience of work, the feed mechanism should be equipped with a sufficiently powerful spring, which could bring the block with the drill to its original position. One end of the spring will rest against the block, and the other against a fixed beam, which should be installed on the rack.

If the drill will not be used autonomously, for greater convenience, you can disassemble its switch and install the on-off button directly on the frame.

Drilling machines based on asynchronous motor

In many home workshops, there are various electric motors that have been preserved after the use of electrical appliances. For the manufacture of a drilling machine, the most suitable would be an asynchronous electric motor, which is installed on drum-type washing machines.

It should be said that the design of such a machine is much more complicated than the above-considered design using an electric drill. Among other things, the motor from the washing machine is quite heavy, which creates increased vibration and requires the installation of a powerful stand.

To reduce vibration, you should place the engine as close to the rack as possible or pick up a fairly heavy, powerful frame.

However, it should be noted that when the engine is located close to the rack, the design becomes much more complicated, since it becomes necessary to install pulleys with a belt drive. When assembling, it is necessary, if possible, to fit all the details as accurately as possible, since the performance of the machine will depend on this.

For the manufacture of the pulley structure, you will need:

1. hexagon
2. Steel clamp ring
3. two bearings
4. Two cut thin tubes, one of which is internally threaded
5. Gear

The movable part of the mechanism can be made from a hexagon, a tube of the appropriate size, a clamping ring, bearings, a tube with a threaded female thread to which the cartridge will be attached. The hexagon is an element of the transmission mechanism on which the pulley is put on.

To ensure a reliable connection with the hexagon, deep cuts are made at the ends of the tube. A compression ring and bearings are driven into the tube. It is necessary to ensure that the structural elements are fastened to each other very tightly, otherwise, the structure will collapse from vibration.

To manufacture the adjustment system of the machine, you will need a pipe with cuts of the appropriate size and a gear, the teeth of which must freely penetrate into the cuts on the pipe. In order not to be mistaken with the places of the cuts on the pipe and their size, you should roll out the plasticine on the pipe and drive the gear along it. The length of the ladder pipe must correspond to the height to which it is necessary to raise the chuck with a drill. The axis with a hexagon is pressed into a pipe with slots.

The design described above is rather complicated in execution, and, let's not dissemble, not everyone will be able to make it. Therefore, the easiest way, in the manufacture of a machine with an asynchronous motor, is to pick up a powerful steel frame and assemble the machine by analogy with a unit with an electric drill. True, it will not be possible to completely avoid vibration, in any case, and it is not necessary to count on obtaining holes of a particularly precise size when using this unit.

Of course, this article indicates only the general principles for the manufacture of home-made drilling machines, and it cannot serve as a guide to action. Therefore, before proceeding with the assembly of the machine, it is recommended that you familiarize yourself with the drawings of various designs.

In addition, radio amateurs, who, as a rule, drill holes of extremely small diameter in printed circuit boards, are recommended to assemble these structures in miniature, replacing the electric drill with a microelectric motor. Together with a voltage regulator, a microelectric motor will allow you to get almost perfect holes. An example of the construction of such a machine can be seen below in the photo.

For all lovers, do-it-yourself product will be a great helper. Such a unit, in a garage or at home, will allow you to make holes with accuracy and accuracy, make milling in wood, drill broken bolts from threads, and so on. However, buying a drilling machine can be quite expensive, and why spend extra money when you can easily make a drilling machine yourself.

General Specifications for Drilling Machine

Drilling machine drawing

For the manufacture will require a minimum of expensive materials. Basically, these are improvised tools that can be found in any garage. Of course, the material must meet the requirements of the apparatus.

For example, for the manufacture of a large stationary machine, one cannot do without a metal frame, and in the case of a desktop unit, only wooden materials can be used.

For all types of structures, three fundamental factors will be required:

• convenient drill feed lever;
• the accuracy of the movement of the drilling mechanism;
• reliable stand.

Undoubtedly, the feed lever should be placed under the working hand of the master, left or right. However, this is not the only condition for convenience. The drill feed lever should not be long, so as not to interfere with work, but not short, so that pressure on the part is easier. For a better idea of ​​arm length, it's worth looking at the blueprints for factory drill presses. There, the length is adjusted to the desired size.

Regardless of which drilling mechanism will be used, it should be fixed with the smallest possible error factor. To do this, the drilling mechanism is best fixed on a vertical rod. However, a solid wood panel with guide rails can be used.

Without a reliable bed, a homemade drilling machine will not only perform poorly, but become dangerous to use. The base of the tool should be twice as wide as the volume of the structure. This width will allow the structure to be stable during the necessary pressure. In this case, the feed lever should not protrude beyond the edges of the bed. This rule does not apply to stationary machines, because they are fixed to the table surface or made with an individual table.

DIY drilling machine

Which engine to use

You can make a homemade drilling machine using several options for the driving force:

• from a drill or screwdriver;
• from an electric motor;
• from a hand drill.

In this case, for each type of structure, the characteristics of a stationary, portable or desktop machine will be determined. In the case of an electric motor, you can make a stationary or desktop device, and in the case of an electric drill, you get either a desktop or portable unit. A hand drill can at all carry the character of a portable device that does not require power.

Drill as a machine tool

In order to get a good drilling machine from a do-it-yourself drill, it is better to make a desktop design for this tool. In this case, it is worth avoiding fixing the machine on the table. An electronic drill is a fairly popular tool, so it will be useful if it can be removed from the machine. In this case, the design on the table will be superfluous.

A desktop filler machine will require the following materials:

• bed 45x30 cm, with a vertical bar attached to it;
• drill mount, well wrapped around the body of the tool;
• metal slider moving along the bar;
• a wheel that plays the role of a lever;
• steel cable, to control the movement of the lever.

For the bed, it is better to use a metal box with a wall thickness of 3 mm. To the box, a square pipe stand is welded. This stand will serve as a barbell or tripod. Next, a tight slider should be attached to the tripod, which will hold the drill holder and the drill itself.

It will be difficult to choose exactly the right slider, so it should be made of metal plates. The free space between the slider and the tripod should be no more than 0.5 mm, moreover, the tripod will be perfectly level.

Further sequence of actions:

• the slider is made 10–12 cm high;
• to it, a holder for a drill is welded on the front side and lugs for mounting the wheel on the back side;
• in the ears, a rod is threaded to which the control wheel is welded, and fixed with a cotter pin or a welded nut;
• on the wheel stem, a steel cable is tightly wound (at least 6 turns), and both ends of the cable are securely attached to the top and bottom of the tripod. Thus, it will take effort to move the slider on the tripod, and the own weight (together with the drill) will not be enough for the slider to fall.

Drilling structure from an electric motor

Such machines are excellent in the role of stationary tools. In order to figure out how to make a drilling machine from an electric motor, you will have to consider the drawings and delve into the field of electrics.

For the machine, a two-phase motor is required, which will greatly simplify the connection and expand the scope of the unit. Such an engine is connected to phase and neutral wires. Incorrect connection will only affect the direction of rotation. If the rotation is in the opposite direction, then the wires are reversed, and the problem is solved.

When making a stationary structure for drilling, you will need:

• a powerful frame for the engine, which will easily move along a vertical line;
• countertop, where the pin will be fixed along a strict vertical line;
• as a pin, can be taken from the car. It will serve as a ready-made engine-moving device;
• attach a wheel for movement and weld the engine holder to the rail.

The working principle of this machine is very simple. The motor drives the drill head through a belt drive. At the same time, the engine and the drill chuck are inseparable during operation and move along a vertical line at the same time, thanks to the joint fastening.

Portable mechanism from a hand drill

It is very convenient to use a drilling machine from a hand drill in cases where it is not possible to connect an electric drill to a power source. For the manufacture of the machine, you can use a wooden frame:

• the base is made of a board 30x20 cm and a thickness of 40 mm;
• a vertical plank is attached strictly at an angle of 90 ° C;
• the vertical wall should also be made of a thick board, at least 30 mm, and metal corners and screws will help to secure it securely.

Metal skids are attached to the vertical wall (they can be taken from old furniture or bought in a store), a hand drill holder is attached to them. Thus, the drill will move freely up and down, however, this is not enough. To prevent the drill from falling under its own weight, a spring of the required elasticity is attached to the drill holder and the base of the machine.

Do not forget about the handle, which will need to be twisted. Nothing should interfere with her movement. The result should be a unit that is driven manually and does not require power.
