Homemade drilling machine. DIY desktop drilling machine: diagrams and drawings

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 bench drills

However, we will not be distracted by the description of all kinds of industrial drilling installations, especially since home master, for whom this article is intended, will hardly be interested in the intricacies of the design of a universal vertical boring 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 carry out drilling work at home, in most cases, it is enough to have an ordinary electric drill.

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

Of course, today in any specialized store sold many models of various machines, including drilling, 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 electric drills
  • Drilling machines based on asynchronous motor from household electrical appliances

Let's 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, electric drill-based drilling machines are most often found in home workshops.

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

The construction of a drilling machine consists of 4 main elements:

  1. Base (bed)
  2. Vertical rack or bar
  3. Feed mechanism
  4. Electric drill

The choice of the base of the machine, the bed, should be taken especially seriously. The more massive it is, the less vibration will be felt during operation. If you still have an old photo enhancer for developing images on your farm, it can be adapted as a base with a stand after a little modification. 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 board with a thickness of at least 20 mm.

When attaching the stand to the bed, it is extremely important to get a right angle, since the accuracy and quality of drilling will depend on this. To the rack with the help of screws, two guides, cut from metal strips, should be fixed, 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 clamped tightly with the metal clamps.

To reduce vibration, a rubber gasket can be installed between the drill body and the shoe. The vertical movement of the pads with a drill is carried out using a lever. To ensure the convenience of operation, the feed mechanism should be equipped with a sufficiently powerful spring that could bring the block with the drill to its original position. One end of the spring will abut against the block, and the other against a fixed bar, 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 survived after the end of the resource of electrical appliances. For the manufacture of a drilling machine, an asynchronous electric motor, which is installed on drum-type washing machines, will be most suitable.

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, you should position the engine as close to the rack as possible, or select a rather weighty, powerful bed.


However, it should be borne in mind 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, as much as possible, to fit all the parts as accurately as possible, since the operability of the machine will depend on this.

To manufacture a pulley structure, you will need:

  1. Hexagon
  2. Steel clamping ring
  3. Two bearings
  4. Two trimming thin tube, one of which is internally threaded
  5. Gear

The movable part of the mechanism can be made of a hexagon, a tube of the appropriate size, a clamping ring, bearings, a tube with a threaded internal thread to which the chuck 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 a 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 attached 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 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 plasticine on the pipe and drive the gears along it. The length of the ladder pipe must correspond to the height to which the chuck with the drill is to be lifted. The hexagon shaft is pressed into the slotted tube.

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, when manufacturing a machine tool with an asynchronous motor, is to pick up a powerful steel bed 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 accurate size when using this unit.

Of course, in this article only general principles making homemade 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 the various designs.

In addition, radio amateurs, who, as a rule, drill holes of extremely small diameter in printed circuit boards, are advised to assemble these structures in miniature, replacing the electric drill with a microelectric motor. Together with a voltage regulator, the 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.

Having your own drilling machine at home is the dream of any master. The most popular are hand drill designs. But this option has a drawback - if necessary, use a drill as an independent tool - you have to disassemble the machine.

However, there are a number of solutions for manufacturing a drilling machine without using a ready-made power tool.

Powerful steering rack drilling machine

For manufacturing you will need:

  • steering rack from passenger car, with dismantled amplifier elements. Of course, used, but preferably not too loose;
  • Several steel corners and profiles of different sizes;
  • Steel sheet 2-3 mm for the manufacture of the bed. You can find a suitable ready-made spare part from old large household appliances;
  • Drill chuck;
  • Electric motor and pulleys with belt. Ideal - from the Soviet;
  • The bearings are in good condition;
  • Access to welding machine and lathe.

The most critical part is the axle with the pulley. It is turned on a lathe. In this embodiment, the chuck is threaded, so a corresponding thread is cut on the lower part of the shaft.

For fastening, 4 bearings are used, 2 ordinary and 2 thrust bearings. The pulley is used from the same washing machine.

We assemble the carriage from suitable corners, on which the working shaft and the engine will be fixed. We pay particular attention to the placement of the thrust bearing support surfaces. The load must be evenly distributed, otherwise one of the bearings will wear out faster.

The frame is welded from a 4 mm steel plate and similar corners. The support bar is strictly vertically welded from metal profile.

On a horizontal surface, we make 6 holes for attaching a vice or a support stand. On the reverse side, nuts are welded on.

With the help of powerful clamps, the steering rack is installed on the profile. Installation is carried out once, with strict control of the verticality of movement. At this stage, a decision is made on which side the steering wheel will be - for the left or right hand.

The fact is that the direction of rotation of the rack mechanism is somewhat unusual for those who worked on a classic drilling machine.

The carriage with a chuck and an engine bracket is additionally supported by two bearings on a profile bar. This is done to compensate for play in the steering rack.

We install two bearings on the carriage

We assemble the mechanism, check the verticality of the stroke. If necessary, adjust it by placing washers under the rail fasteners.

IMPORTANT! If the direction of movement of the chuck differs from the vertical, the drills will always break.

The steering wheel is made of a 10 mm steel bar. For aesthetics, knobs can be carved. The carriage travel is 160 mm, which is sufficient for most drilling applications.

For safety, it is necessary to install around the drive belt pulley protective cover made of thin metal. You can use an old saucepan of a suitable size.

We assemble the engine control unit in a separate box. You do not need to invent anything, the speed controller remained from the washing machine. This option provides a reverse rotation, which adds functionality, especially when tapping or milling.

We install the motor on the carriage. On one side there is an articulated suspension, on the other - a hairpin, a belt tension regulator. Given the age of the washing machine, it is better to replace the V-shaped drive belt with a new one; at the same time, the distance between the pulleys can be set to a more convenient one.

After setting up and final assembly, we paint the metal parts with paint, and the homemade drilling machine is ready to go.

To fix the workpiece, you can use a vise or a stand, which is made for the specific dimensions of the machine.

IMPORTANT! The metal housing must be grounded.

Compact drilling machine

Homemade machine for metal does not have to be bulky and powerful. Most of the work can be done on a small tabletop fixture.

compact, homemade drilling machine

The tool is completely made of metal blanks, except for the electric motor and fasteners from finished parts. All structural elements are made with a CNC milling machine and a lathe. If you do not have access to the machines, you can pick up the components in the furniture accessories store.

Step-by-step assembly instructions

  1. The frame is made of plexiglass with a thickness of 20-30 mm, the base is two-layer. The bottom layer is attached to the table (workbench), on the top we provide a place for installing the heel under the column.

  2. The heel and the column itself were purchased from a furniture accessories store.

  3. The support sleeve is made on lathe, and modified on a milling machine. At the rear, a mother brass nut is installed to adjust the vertical position of the carriage. The sleeve is fixed to the column with a set screw.

  4. The spindle plate is made on a CNC milling machine. Do not be intimidated by the manufacturing technology, the same part can be easily made with a drill and a file. The plate is mounted on a retaining sleeve.

  5. A bracket for the engine with grooves for longitudinal movement is installed on top. This is necessary to tension the drive belt, and rearrange it on the pulleys when changing the rotation speed. The bracket is made in the same way as the spindle plate.

  6. The motor is used asynchronous, with a power of 60 W. The capacitor starting block is made in a separate box.

  7. The spindle plate, together with the motor, moves vertically with the help of a lead screw, the mechanism is visible in the photo, the element is optional, but adds convenience.

  8. The spindle consists of a housing with bearings and a shaft on which the chuck is mounted using a Morse taper.

    spindle after turning

  9. The spindle body is installed in a sleeve, along which it will move vertically when drilling.

  10. The movement is carried out using a lever in which a longitudinal groove is cut.

  11. A pulley with variable diameters is put on top to adjust the rotation speed and torque.

  12. A similar structure, only inverted, is placed on the drive motor shaft. By shifting the belt from one pulley to another, you can easily achieve the required rotation speed.

  13. We assemble the structure, check the performance. The drive belt can be round or flat, depending on which pulleys you use.

  14. Initially, the desktop machine was created for drilling printed circuit boards, but later it was modernized as a more versatile one. For drilling holes at any angles, a self-made three-dimensional coordinate vise for a drilling machine was made.

  15. The design consists of a coordinate plate, machined on the same CNC router and a vice made by hand.

We looked at ways to make a drilling machine from scrap materials. There are many options for execution. You can make a frame from a photomagnifier or use the mechanism of an old microscope. The principle of operation will not change from this.

The main condition is a reliable working surface with a plate or vise, and a mechanism for moving the spindle vertically. The presence of backlash in the mechanism and overall comfort in work depends on the accuracy of manufacturing.

The video shows a homemade drilling machine from an old photo enlarger. We took a tripod and a mount to work.

For all lovers, making a product with their own hands will be an excellent helper. Such a unit, in a garage or a house, will make it possible to make holes with precision and accuracy, make milling in wood, drill out broken bolts from a thread, 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 with your own hands.

General Specifications for Drilling Machine

Drilling machine drawing

A minimum of expensive materials is required for manufacturing. 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, without metal frame cannot be dispensed with, and in the case of a tabletop unit, only wooden materials can be used.

All types of structures will require three fundamental factors:

  • convenient drill feed lever;
  • precision movement of the drilling mechanism;
  • reliable bed.

Undoubtedly, the feed lever should be placed under the master's working hand, 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 the work, but not short, so that pressure on the part is easier to apply. For a better understanding of the arm length, it is worth considering the drawings of the factory drilling machines. There, the length is adjusted to the desired size.

Regardless of which drilling mechanism will be used, it should be fixed with the smallest error factor. For this, the drilling mechanism is best fixed on a vertical rod. However, a sturdy wood panel with runners can be used.

Without a secure bed, a homemade drill press will not only perform poorly but become dangerous to use. The base of the instrument 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 must 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.

Drilling machine do it yourself

Which engine to use

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

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

At the same time, 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 table-top apparatus, and in the case of an electric drill, you get either a table-top or a portable unit. A hand drill may at all bear the character of a portable device that does not require power.

Drill as a tool for the machine

In order to get a good drilling machine from a drill with your own hands, a design for this tool, it is better to make a desktop one. In this case, it is worth avoiding fixing the machine to 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 construction on the table will be superfluous.

A desktop filler machine will require the following materials:

  • bed 45x30 cm, with a vertical bar fixed to it;
  • mount for a drill, 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 stand is welded from square pipe... This stand will serve as a rod 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 find 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, while the tripod will be perfectly level.

Further sequence of actions:

  • the slider is 10–12 cm high;
  • to it, a holder for a drill from the front side and ears for fastening a wheel from the back side are welded;
  • a rod is threaded into the ears, to which the control wheel is welded, and fixed with a cotter pin or a welded nut;
  • on the wheel rod, a steel cable is tightly wound (at least 6 turns), and both ends of the cable are securely attached to the upper part of the tripod and to the lower one. Thus, it will take effort to move the slider on the tripod, and its own weight (together with the drill) is not enough to make the slider fall.

Drilling structure made of 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 electrical engineering.

For the machine, a two-phase motor is required, which will greatly simplify the connection and expand the scope of the unit. Such a motor 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 swapped, and the problem is solved.

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;
  • in the role of a pin, you can take it from the car. It will serve as a ready-made engine-propelling device;
  • attach a wheel for movement and weld the motor holder to the rail.

The principle of operation of such a machine is very simple. The motor drives the drill head thanks to the belt drive. At the same time, the motor 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 40 mm thick;
  • a vertical plate 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 runners 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 that you need to turn. Nothing should hinder its movement. The result should be a unit that is manually driven and does not require power.

Video: Drilling machine from a drill with your own hands

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

In workshops of radio amateurs, home-made mini 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 of ​​how to make a drilling machine (including with the help of a steering rack) comes to mind not only for radio amateurs, but also for people who from time to time need to carry out repair work at home.

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

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 an additive mini drilling machine from a drill with your own hands from only four main components. The first thing to do in order to create a filler machine is to choose the bed - the foundation for the future.

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

Since the drill has an insignificant weight, you should not look for special devices and very durable materials for the stand, you can take wooden planks or chipboard plate.

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

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

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

The accuracy of the drilling process on a self-made mini-unit will depend on the quality of the connection of the vertical column and the bed.

It is necessary to cut two guide strips from steel strips to move the shoe with a drill. Attach these fittings to the rack with screws.

To securely hold the drill in the manufacture of the shoe, 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 machine feed mechanism is a simple lever with which the block with the drill will move vertically. The mechanical device is equipped with a spring that is strong and resilient enough.

One end of the spring element will abut against the block, the other against a bar attached to the table.

To achieve the most convenient use of the mini drilling machine, provided that it is not planned to periodically remove the drill from it, will allow a complete analysis of the drill switch and mounting a separate switch on the bed.

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 performed using an upgraded steering rack. Since buying a new steering rack is not 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 repairs to the part in order to ensure its smooth running.

Instructions for making the bed and installing it:

  • The machine body is made taking into account the dimensions of the drill and column. The table on which the platform with the drilling parts will be fixed must be of 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 a U-shaped steel profile 30x60x30. It is welded to a sheet of metal with a thickness of 2 mm. The stand should be 6-7 cm higher than the column length. The stroke of the rod 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 stopping it.

Themed video material will complement the theme.

Drilling machine for pcb

To assemble a micro boring 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, fastening ring for fixing the electric motor;
  • movable platform of the machine for printed circuit boards - made independently from scrap materials.

When assembling a desktop micro boring 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, the drills will fail when drilling the printed circuit boards. A gap and poor fixation of the motor are not allowed; at high speeds it can be knocked out of the bed.

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

Coordinate table design

If in a homemade 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 modules linear type made of aluminum profile.

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

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

To make a milling table, drawings are first made, calculations are made and component parts are selected.

In this case, the calculation made should be suitable for technical requirements to machine use, including moving masses, speed, acceleration and positioning accuracy.

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

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

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

More details about making a do-it-yourself coordinate table can be found in the proposed video.

Homemade vise for machine tools

If Soviet vices are too expensive for you, and Chinese products are not to your liking, then in addition to the drilling machine, you can make a vise with your own hands.

To collect homemade vise, you must have the following details on hand:

  • screw - thread 20 mm, length - 150 mm, the screw head must have a slot, since sometimes it does not fit the size of the handles, but with the help of a file it is expanded;
  • a screw with a ring is used as a tightening handle;
  • 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 tabletop;
  • 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 must be 10 mm. Studs, screws are installed in the finished holes, nuts and bolts are attached.

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

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

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

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 can have different functionality. So, it can be a compact benchtop drilling machine, characterized by the simplest design, or equipment equipped with multiple work spindles and numerical control.

For drilling holes in various materials, which is performed in a home workshop or garage, you can use equipment made by yourself. 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 funds. The drawings and experience of many masters who have already gone this way will help us in this.

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

It would seem that an ordinary 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. Home-made, in addition to its compactness, has another important quality: you can install drills of various types 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 is so convenient and useful desktop device contains the following building blocks:

  • 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);
  • device for providing feeding;
  • 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, since it protects the entire structure from vibrations, which can adversely affect both the quality and accuracy of the hole obtained, and the comfort of work.

As a material for such a bed, you can use an ordinary furniture board, the thickness of which is more than 2 cm. It is most convenient to use the base of an old photo enlarger for this, slightly modifying 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.

What quality and accuracy 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 block with a drill fixed to it will move. These rails are best made from two strips of steel, which must be securely screwed to the rack with screws.

When making a block, it is advisable 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 shoe 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 schemes for the manufacture of 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. This spring makes the feed mechanism more rigid.

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

An example of a drill from a drill in more detail

As an example, consider in more detail one of the options for a homemade drill, assembled at home.



Making a machine tool using an asynchronous motor

The absence of an extra electric drill on the farm is not a reason to abandon the idea of ​​making a drilling machine with your own hands. To drive the rotation mechanism of such equipment, you can use any Electrical engine... Such engines, which were previously installed on various equipment, will certainly be found in the garage or workshop of any home craftsman.

Asynchronous motors are best suited for the manufacture of a mini drilling machine. washing machines... If you have such a motor, 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.

Considering the fact that the weight of the induction motor is greater than the mass conventional drill, you will need a stronger base and stand to accommodate the feeder.

In order for such a mini drilling and filler machine to vibrate less during operation, it is necessary to install the engine on a strong 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 be able to make such a machine at home, you will need the following structural elements:

  • gear;
  • the hex on which the 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 solid steel.

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

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