We make a drilling machine. How to make a homemade mini-drilling machine with your own hands. Homemade machine based on an asynchronous motor

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 adequate accuracy or drilling quality.

Of course, today any specialized store sells many models of various machines, 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 desires, 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 did not 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 bed.

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 rack.

To reduce vibration, place the engine as close to the rack as possible or choose 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 internal 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.

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.

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:

A drilling machine is a unique device that is essential for a home workshop. It allows you not to seek help from specialized workshops, but simply take and carry out work on the groove yourself.

Thanks to this, a person saves a huge amount of money on the services of turning specialists.

You can make such a device from improvised materials. There is nothing complicated in the process.

For the production of a home drilling machine, you only need an electric drill or a steering rack.

The purchase of industrial units will cost a pretty penny, so it is more expedient to make your own model using drawings with dimensions, which are full on the Internet.

Before proceeding with the creation of the unit itself, a layout should be completed. This is a responsible step that requires a careful approach and drawing up a drawing. It is necessary to carefully measure and display on paper the dimensions of the future machine. If this is not done, something will definitely go wrong in the work.

It is easy to make a mistake, and having a drawing will not allow you to make mistakes. People who neglect this step in creating a drilling machine with their own hands overpay in the process of its manufacture. Things to keep in mind while working:

Drawings with dimensions.

• Length, width and height of equipment;
• The thickness of the aggregates;
• Technical characteristics of electrical equipment;
• Data of the engine that will serve as a drive for your machine;
• Power consumption energy;
• grounding;
• The number of consumables.

The drawing will allow you not only to visually understand how to assemble the equipment, but also how it will look exactly. The project will provide an opportunity to more clearly determine the amount of production costs.

To assemble such equipment in your workshop, you do not need to have specialized items or electrical equipment. All you need is 4 basic ingredients. First of all, a frame should be selected for the filler machine. It will serve as a powerful foundation for a future turning device.

After that, we determine the mechanism of rotation. For him, it is better to choose an electric drill.

Tip: Take a drill that is not too old, but not too new either. The main thing is that it be in working condition, otherwise the equipment can quickly fail.

The third step is to choose a device for feeding revolutions

on the working part of the drill, as well as determine the stand, vertical type. The drill itself is lightweight, so you don’t need to look for heavy-duty materials for the stand. An ordinary board or chipboard will do.

Tip: An asynchronous motor from an old washing machine is ideal as a drive.

The bed, on the contrary, is selected from those materials that will be stronger. It should hold everything on itself, and also dampen the rattling of the drill itself. So that vibrations do not affect the equipment and the accuracy of work, it is best to select strong metals. Very good, an old photo enlarger stand will do as a holder. True, to create a drilling machine with your own hands, you will need to modify it.

Important! The accuracy of the drilled hole will depend on the quality of the connection between the rack and the frame of the unit.

Also, the creator of the home loom will need to use several steel strips to cut out two guide bars. They will help to carry out the movement of the block on which the drill is located. You can use screws to secure them. We take and fasten everything to the rack.

Clamps will help to increase the strength of the fixation of the drill. It is best to use steel, they can withstand a higher load. To dampen vibrations even more, it is best to place a rubber gasket between the block of the machine and the drill. It will help you eliminate the rattling of home equipment during operation.

At the heart of the movement of the machine is the lever. It allows you to safely move the block with an electric drill in a vertical position. A spring will be installed there, which will allow maintaining the drilling apparatus in the desired tension.

Choosing and installing a steering rack for a drilling machine

To make your home equipment work as conveniently as possible, it is best to use an upgraded steering rack during its creation.

If you're going to buy it brand new from the factory, prepare a tidy sum

because it's not cheap at all. A more profitable solution is to choose a used part, best of all from the VAZ 2108.

Tip: As soon as you bought such a spare part, you should carefully inspect it, carry out preventive maintenance and repair if necessary. Thus, it will turn out to give it a smoother ride while working with a drilling machine.

Now let's start making a bed for your future drilling equipment

1. To make the case, you will need to use a drill along with a column. All this should be installed on a table that will serve as a platform for the future drilling machine. The dimensions of the table should be around 20x30 cm.
2. A special structure that will hold your electric drill is installed on the steering part of the unit. Bolts are used to tighten it.
3. To build the rack itself, you must first select a U-shaped steel profile with dimensions of 30x60x30. Then you need to weld it to a metal sheet with a thickness of 2 mm. In theory, the stand itself must be 6-7 cm higher than the length of the column itself.
4. As a rod stroke, it is best for the machine operator to use the VAZ 2108 steering rack, which was mentioned earlier, when creating equipment.
5. To further increase the rigidity of the entire structure during installation, additional ribs should be mounted.

So that the operator does not have problems with starting or turning off the equipment during operation, a practical system for starting and stopping the engine of the drilling machine should be considered.

In everyday life, not a very large machine may come in handy, but drilling equipment for working with micro printed circuit boards, as in the photo.

To make it, the creator will need:

• Micromotor or engine running at high speed.
• Special collet for clamping small drills.
• Several wooden blocks.
• Metal profile U-shaped.
• Retaining ring, which will help to more reliably fix the engine.
• A mobile platform for a machine tool, which is created by hand from all kinds of materials found in everyday life.

Important! So that the machine does not disappoint you in the end and works clearly and accurately, you should pay special attention to lowering the drill. It should be perpendicular to the board.

In the event that the motor is skewed under some circumstances, the user risks incapacitating the drills. During the production of home drilling equipment, you need to carefully monitor the quality of fixing the motor. If it was installed unreliably, when the engine is running at high speeds, it will simply be pulled out of the frame. This is fraught with damage to your property and the risk of harm to health.

How to make a coordinate table

In a home drilling machine, the role of the coordinate table will be carried out by the feed mechanism. And the same table, but for milling equipment, has a slightly different design. Therefore, it should be considered more carefully.

This equipment is a special manipulator, which consists of the number of axes required by the user. It is needed to move specialized technological heads of drilling equipment in several directions and planes at once.

Important! To make a milling table at home, one cannot do without the use of several linear-type modules. They must be made of aluminum profile.

To transfer motion when creating a milling table, you should use a special gear rack, as well as a reinforced belt. Instead, a ball screw element will do.

To adjust the control of the coordinate table, the creator will need to use the CNC or controllers. Thanks to their installation, the user of the equipment has the opportunity to manage the technical tasks assigned to the machine.

Important! When creating a milling table for a drilling machine, be sure to make a drawing before you get started. This will allow you to clearly understand the algorithm of actions and save yourself from unnecessary mistakes.

The calculation in this case is carried out taking into account the technical characteristics of the drilling unit itself. The design itself can be both lightweight and with increased strength. And also 2 or 3 coordinates can be used there. First of all, before you create a machine, you should understand its main role in your home workshop. And start from this in the design process and further production.

When everything is ready, you need to make a vice, otherwise you will not be able to fix the part at home, it is strictly forbidden to hold it in your hands. Purchasing an old Soviet vise made of steel or cast iron can be expensive. Chinese-made models, not everyone will like them, to the extent of their fragility. Therefore, one of the economical options would be to make them yourself.

You will need:

• A screw with a thread of 2 cm and a length of 15 cm. There must be a slot in the head of the fastener.
• A special screw with a ring that is used for tightening.
• Hairpins.

You should make a motionless sponge. How to make this element? To create, use a pine tree. It is affordable and quite durable. The board should be grafted to the countertop.

To make the mobile part of the vise, you need a board with dimensions of 2 cm thick and 1.8 cm wide. The length of the movable jaws for clamps must be from 50 cm.

All that needs to be done is to cut holes with a diameter of 2.1 cm. In the studs, this diameter will be 1 cm. Then the creator simply inserts the studs together with the screws into the finished holes, after which he baits the nuts and tightens them with bolts.

And this completes the production of home vices.

When you have created your home drilling machine, you should definitely check it out.

Plug the motor into the outlet and if you did everything right, you have no short circuit, no uncharacteristic sounds for the unit to work - you can congratulate yourself on the successful completion of the project.

A homemade machine will allow you to perform simple drilling operations at home and save on the services of auto repair shops or turners.

The only thing is that in order for the equipment to work as long as possible, do not be shy and do not be lazy to inspect the working surfaces together with the engine once every six months for damage or wear of parts. Timely identification of the problem will allow you to save yourself from real trouble.

It is not necessary to spend money on a bench drilling machine, because it is not so difficult to make it yourself.

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 frame must also be massive and, preferably, with the possibility of fixing the machine to 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 eyelets 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.

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.

It is advisable to make a drilling machine with your own hands in those situations when in a home workshop or garage it becomes necessary to drill holes in parts of various configurations, as well as made of different materials. It should be noted that such a device makes it possible to obtain holes with a sufficiently high level of quality.

When you need a homemade drilling machine

In manufacturing or repair enterprises, where the drilling operation is considered the most common, a special device is used to perform it, the models of which may have different functionality. So, it can be a compact desktop drilling machine, which has a simple design, or equipment equipped with several work spindles and numerical control.

For drilling holes in various materials, which is performed in a home workshop or garage, you can use do-it-yourself equipment. Naturally, for home use, you need a simple device that can be made from components and materials found in almost any garage or home workshop.

And in this article we will not leave unanswered the question of how to make a drilling machine at home, while spending a minimum of money. The drawings and experience of many craftsmen who have already passed this path will help us in this.

The need for such mini drilling equipment for metal, wood or plastic most often arises among those who are used to independently performing various repairs in their house or apartment. Also, quite often, radio amateurs are puzzled by the construction.

It would seem that a conventional drill can be used to perform such an operation, but such a tool is not always able to provide the required quality and accuracy of drilling operations. Homemade, in addition to its compactness, it has another important quality: drills of various types can be installed on it.

Drilling machine from a conventional drill

To make a small but functional drilling machine for your home workshop, you do not need to purchase special materials and components. The design of such a convenient and useful desktop device contains the following components:

• the base, which is also called the bed;
• a mechanism that ensures the rotation of the working tool (a conventional drill can be used as such a mechanism);
• supply device;
• a vertical stand on which the rotation mechanism is fixed.

The stand on which the drill will be mounted can be made from a chipboard sheet. This material is quite capable of supporting the weight of such a device. The bed of such a mini machine should be more massive, as it protects the entire structure from vibrations, which can adversely affect both the quality and accuracy of the resulting hole, and the comfort of work.

As a material for such a bed, you can use an ordinary furniture plate, the thickness of which is more than 2 cm. It is most convenient to use the base of an old photographic enlarger for this, having slightly modified its design. Sometimes an old microscope is used, but this is a rather rare option, since such an assembly will not be large enough and its use will be limited.

The quality and accuracy that a homemade drilling machine will provide depends mainly on how correctly and reliably the connection of its base and vertical rack is made. Important elements of such a micro machine are two guides along which the shoe with the drill attached to it will move. Such guides are best made from two strips of steel, which must be securely screwed to the rack with screws.

In the manufacture of the block, it is desirable to use steel clamps that will securely fix the drill on it. In addition, in order to avoid unwanted vibration processes during drilling, a thick rubber gasket must be installed at the junction of the block and the drill.

After that, you need to make a feed mechanism for such a mini machine, which should ensure the movement of the electric drill in the vertical direction. The manufacturing schemes for such a mechanism may be different, but it traditionally contains a lever and a spring in its design, which is attached at one end to the rack, and at the other end to the block with a drill. Such a spring gives the feed mechanism greater rigidity.

A drilling machine from a drill that is not planned to be removed from it can be made more convenient to use if you disassemble the native switch of the drill and mount a separate button on the frame of the mini equipment. This button will always be at your fingertips and will allow you to quickly turn the device on and off. As you can see, it is not difficult to make a drilling machine from a drill, for this it is quite enough to carefully read these instructions or watch the training videos in this article.

An example of a machine from a drill in more detail

As an example, let's take a closer look at one of the home-made drilling options assembled at home.

Making a machine tool using an asynchronous motor

The absence of an extra electric drill in the household is not a reason to abandon the idea of ​​​​making a drilling machine with your own hands. Any electric motor can be used to drive the rotation mechanism of such equipment. Such engines, which were previously installed on various vehicles, are likely to be found in the garage or workshop of any home craftsman.

Asynchronous motors, which are equipped with washing machines, are best suited for the manufacture of a mini drilling machine. If you have such an engine, you can confidently use it to make home drilling equipment. Making drilling equipment with such an engine at home is somewhat more difficult than using a drill, but the power of such a machine will be much higher.

Given the fact that the weight of an induction motor is greater than that of a conventional drill, you will need a stronger base and stand to accommodate the feed mechanism.

In order for such a mini drilling and filler machine to vibrate less during operation, it is necessary to install the engine on a powerful base and place it as close to the rack as possible. But here it is important to maintain the correct distance, since the convenience of mounting the belt drive depends on it, due to which the rotation from the engine will be transmitted to the drilling head.

In order for you to make such a machine at home, you will need the following structural elements:

• gear;
• a hexagon on which a pulley will be put on;
• two bearings;
• tubes in the amount of two pieces, one of which must be with an internal thread;
• clamping ring, which must be made of durable steel.

The hexagon also connects to the metal tube, bearing and clamping ring. Such a connection must be very reliable so that the resulting node does not collapse during operation.

The mechanism necessary to ensure the supply of a tool in such a mini machine should consist of a tube on which cuts are first made and gears. The tube will move by connecting its teeth with these files. An axle with a hexagon is then pressed into this tube, the height of which must correspond to the required tool feed.
