Several step-by-step instructions for making a drill press. How to make a homemade mini drilling machine with your own hands Base for a drilling machine with your own hands

You don't have to spend money on a benchtop drill press because it's not that difficult to make your own.

To do this, you will need to purchase, manufacture or use used parts. We will tell you about creating several designs, and you can choose your model for assembly.

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

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

Tabletop drilling machine made from drill

The most common design can be considered a machine made from a hand or electric drill, which can be made removable, so that it can be used outside the machine, or stationary. In the latter case, the switching device can be moved 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 frame can be made from a solid cut hardwood, furniture board or chipboard. Some people prefer a metal plate, channel or tee as a base. The bed must be massive to ensure structural stability and compensate for vibrations during drilling to produce neat and accurate holes. The size of the frame made of wood is at least 600x600x30 mm, of sheet steel - 500x500x15 mm. For greater stability, the base can be made with eyes or holes for bolts and attached to the workbench.

The stand can be made of timber, round or square steel pipe. Some craftsmen 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 secured using clamps or brackets with a hole in the center. The bracket is more reliable and provides greater accuracy when drilling.

Design features of the drill feed mechanism

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

  • spring;
  • articulated;
  • screw jack type design.

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

The drawings and photos show the basic designs of tabletop drilling machines, which can be made from electrical and hand drill.

Machine based on the steering rack of a passenger car

A steering rack for a car and a drill are quite massive products, so the frame should also be massive and, preferably, with the ability to attach the machine to a workbench. All elements are welded, since connections with bolts and screws may not be sufficient.

Stanin and support post welded from channels or other suitable rolled products, about 5 mm thick. Steering rack secured to a stand, which should be 70–80 mm longer than the rack, through the eyes of the steering column.

To make the machine more convenient to use, the drill control is placed in a separate unit.

Assembly procedure for tabletop drilling machines:

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

All fastenings must be made as securely as possible. It is advisable to join one-piece steel 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.

You can also find ready-made stands for drills on sale. When purchasing, you need to pay attention to the weight of the structure and size work surface. Lightweight (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 advisable to use it in the machine, you can make a design based on asynchronous motor, for example, from the old washing machine. The design and manufacturing process of such a machine are quite complex, so it is best to make it by a craftsman with sufficient experience in turning and milling work, and assembling electrical circuits.

The device of a drilling machine with a motor from household appliances

To familiarize yourself with the design, we provide assembly drawings and detailing, as well as the characteristics of assembly units in the specifications.

Homemade machines for drilling printed circuit boards

Mini-machines for drilling circuit boards by radio amateurs also borrow the drive from various low-power devices. In this case, cutters for cutting photographs are used as levers, soldering irons, and collet pencils instead of a chuck. The drilling site is illuminated with LED flashlights - there are plenty of opportunities for technical creativity.

Video 7. Mini machine for drilling circuit boards

An electric drill is a universal tool, since its chuck can hold not only drills and cutters, but also wooden parts, in case the device is used in a lathe. The need for a drilling machine arises when a home craftsman needs to drill holes strictly at right angles. In this case, the master is faced with a choice: buy a ready-made stand for drilling or make a machine from a drill with your own hands. We will tell you how to implement the second option.

When making a stand for securing a drill, you need to understand the principle of its operation and show imagination in the manufacture of its individual components.

Rack option No. 1

For example, below are instructions for making a device for a drill from simple scrap materials.

  1. To attach the drill to the slide, clamps are used, under which a rubber gasket is placed.
  2. To raise and lower the moving part of the slide to which the power tool is attached, a stand with a lever is used.
  3. To limit the drilling depth, an adjustable stop is installed under the lever.
  4. The fixed part of the slide is attached to the pipe using a flange.
  5. The vertical and horizontal parts of the pipe are connected by an angle. Required when connecting maintain a right angle. The vertical pipe is fixed in a flange screwed to the frame. Instead of a pipe, you can use “kerchiefs” made of chipboard, which are secured to the frame and to the stationary part of the slide using euroscrews (confirmats).
  6. On the movable platform it is necessary to make 4 holes for the clamps used to clamp the device body. Also on the side that will be turned towards the stationary part of the rack, it is necessary to glue the slats. For better glide, they are lubricated with paraffin.

  7. To prevent the body of the device from falling down, you can install 2 stops at the bottom, as shown in the figure.

  8. To align the unit body at a right angle, you can glue a rail required thickness(thickness is determined by selection method).

  9. The guides in this design are made of aluminum profile. But you can also replace them with ball (telescopic) guides, which are used to install drawers in furniture. The purpose of the guides is to provide a rigid (without play) and at the same time movable connection of the parts of the rack.


  10. To assemble the lever so that it can still move, the nut should not be tightened all the way. To fix the nut and prevent it from unscrewing spontaneously, another one is used, which is screwed next to it.

  11. The part of the lever attached to the movable platform should be rounded at the end.

  12. If you need the unit to rise to the top position after drilling, you can install a spring by attaching one end to the movable platform and the other to the horizontal part of the pipe. If the spring is short, you can lengthen it with a cord.

Rack option No. 2

The figure below shows another homemade drilling machine, the stand for which can be made from thick plywood, and the remaining parts from wooden beams.

The role of a guide in a drilling machine made from a drill is played by an aluminum profile. But, if you don’t find such a profile, you can replace it with furniture guides(telescopic).

Rack option No. 3

If you have some lying around your house Soviet era photo enlarger, then it can serve as the basis for a stand for a drill. This design already has rigid guides, as well as a gear mechanism that ensures vertical movement of the carriage along them.

You only need to modify the design a little by attaching clamps to the carriage and comfortable handles to the height adjuster.

Well, if you don’t have the desire to design accessories for a drill with your own hands, or you simply don’t have time for it, but you still need to drill a hole with a drill strictly at a right angle, then you can buy a ready-made stand for about 1,200 rubles.

Other options for drill machines

The drilling machine can serve as a motor for constructing various woodworking tools. Let's look at what other machine you can make from a drill with your own hands.

Fraser

To make a router using a drill, you will need to take a regular clamp used for water pipes.

You will also need to find some chipboard (you can use a slab of old furniture), and then assemble a structure such as in the figure below.

This type of router can be used, for example, for milling a groove in the end of a tabletop, for filling a T-shaped profile, or for shaped milling of the ends of wooden parts. Of course, good quality Milling in this way is difficult to achieve, since the device does not have enough revolutions. For comparison, the spindle of a router can rotate at a speed of 26,000 rpm. and more, due to which high quality surface treatment is achieved.

You can also make a milling machine from a drill if you clamp it in such a way as shown in the figure below. In this way, a quarter is selected in a block for inserting glass, for example, when making a window.

To turn small, round parts, you can make a device in which a drill will impart rotational movement to the workpiece. The most in a simple way To perform turning work on wood can be called the one shown in the figure below.

This wood lathe can be made in minutes. To make it you will need wooden beam or a board, a couple of corners, and also a sharpened bolt.

A more “advanced” drawing of a lathe, which you can make from a drill with your own hands, is presented below.

If you do not have the opportunity to make such a device from metal, as shown in the drawing, then you can get by a pair of clamps, attached to the workbench.

The first clamp with a clamp can be used to secure the device to the workbench.

As a clamp for a drill, you can use a small vice with a clamp clamped in it. Use the second clamp to clamp the homemade tailstock with a screw screwed into it to center and support the part. The end of the screw should be ground to a cone.

As a tool, a block of the required thickness is pressed against the workbench.

It is also not difficult to design a homemade lathe from wooden blocks, as shown in the following figure.

For precision turning work with long and big details It is recommended to make a lathe from metal profile (square).

When manufacturing this design, it is necessary to accurately maintain the alignment of the headstock and tailstock. The unit can be secured to the headstock with a pair of clamps.

The tailstock must be movable so that parts of different lengths can be processed.

The tool rest should also be movable and move both along the bed and across it so that it can be moved closer to the workpiece to reduce leverage. If the lever is too large, the tool may be torn out of your hands and the part out of the chuck, which can result in serious injury.

It is important that the support platform rotates, for example, when processing a part at an angle.

If you make such a machine, it can easily be converted into a universal one. It is enough to clamp an emery or felt wheel in the chuck of the device, and the structure turns into grinding machine from a drill. In the same way, you can make a sharpening unit from it.

More simple model universal machine easy to make from regular planed boards. To do this, you need to cut it into parts and assemble the structure, as shown in the figure.

This is what the bed looks like if you remove the table.

The thickness of the board used in the design is 2 cm. The length of the product is 50 cm. The width of the device is 20 cm.

The height of the stands is 9 and 14 cm. The height can be different and depends on the diameter of the grinding wheel that will be used. The entire structure is screwed together with self-tapping screws. It is recommended to coat the joints of parts with glue before assembly.

There are 2 clamps attached to the top of the posts, one of which is cut and bent. A cut piece was used as a soft pad. polyethylene tube, nailed down with nails.

It is necessary to make a small cut (groove) on the frame and widen it from the bottom side so that the head of the coupling bolt does not interfere.

Next, you should twist 2 planks measuring 20 X 27 cm with a block between them, the thickness of which is 4 cm (this way you will get a table). The block is needed so that the hand can move freely between the planes while screwing the table to the frame.

A groove is also cut in one plank to secure the table to the base. After this, the table can be attached using a screw and washer.

Thanks to the grooves, the table can be moved to the required distance to the chuck. If the table is rotated, it will be possible to move it across the machine. The length of the groove determines the distance the table can be moved.

After attaching the drilling machine, you will receive a universal fixture.

Now, if you clamp the drill chuck grinding wheel— you will receive a grinding unit. The presence of reverse in the unit during grinding is desirable, but not necessary.

If you install abrasive disc(for metal) from a grinder, then it becomes possible to cut metal rods. When cutting metal, be sure to wear safety glasses. You can also install a toothed cutter and use it to cut thin plastic.

When installing abrasive wheel- it turns out to be a sharpener.

This unit can be used for sharpening knives, drills, plane knives, and also for sharpening tools for a wood lathe.

If you fix the guides on the table and install a drill in the chuck, you will get an additive machine.

Thus, the drill, thanks chuck, is the basis for creating machines for various purposes. This increase in functionality of a conventional drill will be very useful for home handyman, at whose disposal various technological operations appear.

For a skilled person, nothing is impossible. And if desired, a talented enthusiast is able to make anything. Today we will talk about how to assemble a drilling machine with your own hands, since this topic is more than relevant.

Buying a factory model, even if we are talking about used equipment, requires considerable expenses family budget. We will tell you how to assemble a metal drilling machine from available materials with minimal investment.

Today there are 2 proven designs that are easy to assemble in a “garage” environment.

This is a machine based on an electric drill and a unit based on a conventional asynchronous motor from a household appliance. Let's consider each of the options in turn.

As the basis for our future machine we will take an ordinary electric drill.

This tool is lightweight. This suggests that we do not have to use structures made of durable metals. Ordinary wooden boards or even chipboard will be quite suitable for our purposes.

A homemade metal drilling machine based on a drill consists of four main components, such as a bed, a vertical stand, an electric drill and a feed mechanism. The choice of the base of the machine (bed) is a very important moment, since the intensity of vibrations during operation will depend on the strength and massiveness of this structure.

This is very important, since a massive bed will improve the quality of workpiece processing.

What can be used as a base for the machine? If you have a Soviet photographic enlarger at home that was used to develop photographs, you are in luck.

After some manipulations, it can be easily turned into a full-fledged base for a homemade drilling machine. If you couldn’t find a photo enlarger even on the used equipment market, you can replace this element with an ordinary structure made from a 20-mm furniture board. It will provide sufficient rigidity for precise work.

When fixing the frame to the stand, it is very important that a perfectly right angle is maintained between them.

This will increase drilling accuracy.

On the rack you need to fix two guides, which can be made from ordinary metal strips. The guides will move the block with the drill fixed on it using clamps. For additional vibration isolation of the tool, it makes sense to put a rubber gasket between the electric drill and the block.

Vertical movement of the block must be carried out using a lever.

In order not to experience discomfort during drilling, it makes sense to equip the feed mechanism with a spring capable of returning the tool to its original position.

The spring must be fixed on one side to the block, and on the other to a fixed beam.

If you do not plan to use an electric drill autonomously, you can take care of the ergonomics of your homemade metal drilling machine. To do this, disassemble the drill switch and install the start button in a location convenient for you.

That's all, actually.

If you follow the above algorithm, assembling a drilling machine with your own hands will not be a problem for you.

Homemade machine based on an asynchronous motor

If you look hard enough, you will most likely find a wide variety of electric motors in your household, from household appliances. The best choice for a metal drilling machine - an asynchronous motor, which is used in drum washing machines.

Be prepared for the fact that assembling such a machine will be somewhat more difficult.

First of all, you will need a more massive stand that will absorb significant vibrations from the washing machine motor. To reduce them to a minimum, you need to install the motor closer to the rack and provide a reliable frame.

But keep in mind that the close location of the motor relative to the rack complicates the design, since it will be necessary to mount a pulley with a transmission. When assembling such a unit, adjust all parts and components as accurately as possible.

The performance characteristics of the machine will directly depend on this.

To assemble the pulleys we will need a gear, a hexagon, a metal ring for clamping, 2 bearings and 2 pieces of pipe, one of which is with internal thread. The movable structure is made of a hexagon, a tube, a ring, bearings and a threaded tube where the cartridge will be fixed.

The hexagon acts as a transmission element onto which the pulley is placed.

To be sure of the reliability of the connection with the hexagon, it makes sense to make cuts at the ends of the tube onto which the ring and bearings are placed.

Make sure that all parts of our structure are fixed as securely as possible to avoid destruction due to vibration.

Now we begin to create the control system of our unit.

Do-it-yourself desktop drilling machine: diagrams and drawings

To do this, we use a pipe with cuts and a gear, the teeth of which should easily penetrate into the cuts we made. To make them as accurate as possible, first apply plasticine to the pipe and run the gear along it. Please note that the ladder pipe must have a height corresponding to the lifting height of the cartridge. The axle with a hexagon must be pressed into a pipe with pre-made slots.

As you understand, the design described above is not easy to manufacture, and not every master is able to bring such a “project” to completion.

If you are not sure that you have the skills to assemble such a drilling machine, give preference to the first design based on an electric drill.

conclusions

We have given two of the most successful examples making drilling machines with your own hands.

Since the information presented is general character, we recommend that you familiarize yourself with the drawings of such equipment in more detail to avoid inaccuracies and various kinds errors during the manufacture of the unit.

Practice shows that experienced master easily cope with an ambitious task, such as creating a metal drilling machine on your own.

All that remains is to wish you good luck.

Types of drilling machines and their purpose

Drilling metal

Types of drilling machines and their purpose

Drilling refers to the method of shaping internal cylindrical surfaces in a solid workpiece material using a drill.

Drilling is the only technological method cutting, which allows you to obtain holes in a continuous layer of workpiece material. Drilling machines also process holes that already exist in workpieces in order to obtain the desired shape, size and roughness of such holes.

Processing on drilling machines is carried out with multi-blade cutting tools, which ensures high productivity.

Drilling machines are divided into following types: vertical drilling; radial drilling; for deep drilling; central and multi-spindle.

In the tool shops of machine-building enterprises, vertical and radial drilling machines, which are universal, are most common.

One of the most important technical characteristics drilling machine is the largest nominal diameter drilling, equal to the maximum diameter of the hole that can be drilled on this machine, using a standard twist drill, in a solid steel workpiece with a tensile strength = 500-600 MPa.

For vertical drilling machines with a column, this diameter is 18-75 mm, and for tabletop drilling machines - up to 12 mm.

1, a shows a vertical drilling machine with an aggregate layout. A hollow column is installed on its foundation slab.

The table on which the workpiece is placed is moved along its vertical guides manually (with handwheel 2). The spindle is mounted in the drilling head and is subjected to rotational and vertical linear translational motion. The latter is done manually (flywheel 5) or automatically.

Installed in the spindle cutting tool. The drilling head contains drive mechanisms for the rotational and translational motion of the spindle, an electric motor and machine control mechanisms. The drilling head can be moved manually along the vertical guides of the column. The required relative position of the drilling head and table is established (taking into account the size of the workpiece) before processing begins, after which this position is fixed.

Inside the column there is a counterweight that balances the drilling head.

Do-it-yourself drilling machine from a drill

1. General form vertical drilling (a) and radial drilling (b) machines

In order to begin processing each subsequent hole, the workpiece is reinstalled on the table so that the axis of the tool coincides with the axis of the hole being machined. Therefore, processing large-sized heavy workpieces with vertical drilling machines a large number holes is associated with significant labor and time costs.

To avoid these costs, when processing heavy and complex workpieces, it is advisable to use radial drilling machines (nominal drilling diameter up to 100 mm), which ensure accurate and fast movement of the tool relative to a stationary workpiece and its installation in the required location.

A radial drilling machine consists of a base plate on which a stand with a fixed column is installed. It is fitted with a sleeve that can rotate 360° relative to the column.

Along the sleeve, as if along a guide, the sleeve moves (using a special drive) in the vertical direction, along the horizontal guides of which the drilling head moves.

Speed ​​and feed boxes and a spindle assembly are mounted inside the head, and machine controls are located on the front panel of the head. The spindle can rotate around its axis and move in the vertical direction. The workpiece is placed on table 8 or directly on the foundation slab.

Before processing begins, the sleeve, sleeve and drilling head are moved so as to set the tool in the required position relative to the workpiece.

In this position, these units are fixed using appropriate mechanisms located in the lower part of the sleeve, above the cabinet and in the drilling head. Then the spindle is rotated, its vertical feed is turned on, and processing is performed.

How to assemble homemade drilling machines?

IN modern production the use of various machines has become so popular that now not a single decent workshop can do without this equipment.

Indeed, the machine allows a person to engage in such work that he can complete on his own, if he can, then with a huge investment of time.

This applies to the processing of metals, wood and other dense materials, which are quite difficult to use without specialized equipment.

Another big advantage of the machines is that their manufacture is not complicated.

Homemade drilling machine from a finished drill

If desired, a person with basic mechanical skills can assemble a homemade drilling machine in a couple of days.

It is the assembly of homemade drilling machines that will now be discussed in this article.

Features and purpose

Machine tools are used extremely widely in industry.

In fact, it was their invention that became a real revolution in the world of industrialists who wanted to quickly increase production rates.

Indeed, the presence of machines in production is a real benefit. A high-quality drilling and grooving unit is capable of performing work with amazing accuracy, while reducing the requirements for the initial skills of the person who uses it in the work.

This phenomenon can be explained very easily.

Let's imagine that you need to create a metal plate with ten holes on it.

The holes must be of different diameters. From the smallest to the largest. The plate has a thickness of 3-5 mm. That is, to work on metal you will have to use a fairly powerful drill.

Note that large drills are used with large tools; such drills are usually quite heavy.

It will be difficult for an untrained person to even hold them in their hands. Not to mention performing more or less lengthy work.

Plus, you should understand that filigree precision will be required of you, because this part is just part of a larger mechanism.

One small mistake, and the entire structure can become completely unusable. This is especially true for drilling machines printed circuit boards.

When processing boards, the accuracy of their marking is determined by tenths of a millimeter.

If you give a person everything necessary equipment, then even with experience he will tinker with the plate for no less than a couple of hours.

When drilling boards, this time investment can double.

And this is only if you have work experience and relevant skills.

If it is not there, then preparing just one plate can, without exaggeration, take a whole day.

Homemade machine High Quality assemblies

If you use a machine, the operating time is reduced several times. All the necessary tools are already fixed on it.

The drill is stabilized and clearly guided.

All you need to do is install the plate correctly on coordinate table, start the engine and drill a hole. Then change the position of the part and continue working using the same technology. As you can see for yourself, production productivity is reaching a whole new level.

Machine components

Now let's turn directly to the components of the machine. After all, if you are interested in the question of how to make a drilling machine, then first of all you need to understand the parts that will be used when assembling it.

Fortunately, a homemade drill press consists of a few basic parts.

Their quality determines the quality of the device itself, but everything here depends on many factors.

So, the drilling machine consists of:

  • Beds or bases;
  • Fastening strip or frame;
  • Mechanism for adjusting the position of the device;
  • Fastenings for the working mechanism;
  • A motor or mechanism that directly performs drilling;
  • Adapters, collets and other similar materials;
  • All kinds of handles, stabilizing legs and other additional parts that are used to improve the design of the device.

It's worth noting that it makes little difference whether you're looking at a PCB processing machine or a standard stationary sample.

You will of course use various details for assembling a homemade drilling machine, however general scheme will remain the same.

The difference will only be in specific details and their dimensions.

Using an old table as a machine bed

For example, a homemade desktop unit for drilling circuit boards for electronics will be mounted on a shallow frame. In most cases, you don't even need a cabinet. It will be enough to take a large, heavy rail, which in its weight will be at least half of the structure of the device.

Also, when developing boards, you will need a much simpler and smaller motor, since drilling boards requires more detailed work, where power is not a priority.

Selection of parts for assembly

First of all, always pay attention to the bed or base.

The base for an impressive machine must be very strong and stable. For such purposes it is necessary to use a table with good supports, special stands, etc. Even a cabinet of the required size and dimensions will do, but it’s up to you to decide.

If we are considering a desktop sample, then the table here will act as the first base on which the machine itself is already installed.

Do-it-yourself drilling machines from a drill (drawings, video)

In this case, the frame can be made from a metal plate or something similar.

Interestingly, some craftsmen manage to assemble a table or machine bed even from ancient parts of a photographic enlarger. That is, you can use a wide variety of details in your work.

The main thing is that the table or stand on which the device is mounted is extremely stable and does not vibrate during operation.

You can make the mounting frame yourself.

The same applies to the fastening for the working mechanism. Here you can use a metal corner with drilled holes or something similar.

The corner is attached to the table with screws or welded to the frame. A lifting mechanism is also installed there. It is made from an old jack, shock-absorbing pipes, sliding rails and other similar mechanisms.

The engine will need to be quite powerful to operate, so you will have to go through several options.

Moreover, the table and base of the machine must easily support its weight and dampen vibrations during operation.

An asynchronous engine from washing machine or something similar.

You can use the engine from the drill or the drill itself.

Scheme of creating a machine

If we consider only the simplest models of equipment that can be quickly assembled with your own hands. Then the standard drilling equipment assembly diagram is best suited for these purposes.

However, we note right away that there are two main technologies for its assembly.

The first is simpler, it involves using a ready-made drill, which is simply screwed to the mounts.

The second one is quite difficult option, and it consists of assembling a machine from a separate engine, collets, guides, etc.

  1. We assemble the table and base for the machine, and fix the frame.
  2. We install the main stabilizing frame.
  3. We connect the mount for the engine.
  4. We are in the process of installing a lifting mechanism.
  5. If necessary, we install springs and shock absorbers.
  6. We mount the working element of the machine.
  7. We connect all the contacts and install the drill.

When assembling a machine from a finished drill, your work will be easier.

All you have to do is create a strong frame with the ability to raise and lower the drilling mechanism, to which you can then connect the drill.

There is no need to tinker with power supplies and engine assembly here. You just need to securely secure the tool and connect it to electricity.

Assembly of the engine already involves the installation of a power supply, a converter and, if the engine has indirect transmission of forces, mechanisms that transmit them.

Therefore, to prepare the second option you will have to spend more time, effort and energy.

And certain engineering skills will also not be superfluous.

“From the material presented by the author, you will learn how you can independently make a budget drilling machine from an ordinary electric drill.
Every craftsman would like to have a similar machine on his farm, because in comparison with factory analogues it will cost tens of times less, and if all the spare parts and components are available, then it’s completely free.

The author of this machine is Igor Stasyuk, for which he Thank you very much, shared step by step photos assembling the machine with the people. The design is quite interesting and at the same time simple. Corners and 4 legs are welded onto a base made of a 3 mm sheet of metal; a 500 mm rod made of professional pipe is welded onto this plate. square section, the slider is made of 2 corners welded into a pipe and placed on a lifting column with a gap so that the slider can move up and down along the column. Lifting mechanism it is activated by a cable stretched from the top point to the bottom, and on the slider the cable makes several turns.

So, let's take a closer look at what exactly the author needed to assemble the machine? And also the whole step-by-step process.

Materials
1. sheet metal 3 mm
2. fittings
3. corner
4. cable
5. drill
6. vice for workpieces
7. bolts, nuts, washers, engravers
8. drill clamp
9. paint
10. professional square pipe
11. drill

Tools
1. welding machine
2. grinder (angle grinder)
3. drill
4. file
5. vise
6. clamp
7. caliper
8. ruler
9. corner
10. level
11. sandpaper
12. brush
13. hacksaw for metal
14. emery

The process of creating a drilling machine from a drill.
And so, first of all, the author makes the base of the machine from sheet metal 3 mm, cuts out the workpiece using a grinder (angle grinder) and welds 2 corners and 4 legs from a steel rod or fittings into the lower part. The length of the legs should be the same so that there is no distortion of the frame.

The corners and legs are welded on.

Making a slider! Take 2 corners and apply them to a professional square-section pipe that will serve as a lifting column and tighten them with a clamp.

It is tacked along the edges by welding in order to simply attach it for now, and only then specifically weld the normal seam.

This is actually how the preparation turned out.

The lifting column is made from professional square-section pipe 500 mm long.

A bracket with a movable shaft is welded onto the slider body, onto which the cable turns will be made.

IN drilled hole thread is cut.

The handles of the lifting mechanism are made of reinforcement.

There is a head on the shaft that will serve as the base for the handles.

And so, 3 handles are welded on for the convenience of raising and lowering the drill through the mechanism.

Installed on a lifting column.

A loop like this is made at the end of the cable.

Attention! The cable is attached at the bottom using a loop, then several turns are made on the shaft and tension is applied in the upper part of the lifting column.

I hope the lifting principle is clear and without explanation)

A square pipe is welded onto the corner.

This is actually the mount for the electric drill.

Then the drill is installed and secured with a clamp of bolts and nuts.

Now let's go back to the lifting mechanism again.

At the top of the lifting column, a nut is welded and a bolt is screwed into it, a cable is attached to the bolt itself, and when the bolt is tightened and unscrewed, the cable is tensioned to the optimal level.

It is advisable to pre-lubricate the moving components with grease or lithol.

These small vices can be purchased at a hardware store in the tools section.

All parts were polished by the master using sandpaper and then painted.

A self-made drilling machine allows you to drill holes in different materials at a sufficient quality level at home.

1 Homemade drilling machine - who needs it and why?

Drilling in the extensive list of all kinds of plumbing operations is considered among specialists to be the most accessible and truly simple procedure. It is usually performed on special drilling units, which can have different functionality and some design features. The modern machine tool industry produces many types of drilling machines, ranging from very simple ones (for example) to CNC units that have several spindles.

It is clear that in most cases the home craftsman simply does not need such machines, since they are intended for performing serial operations. And in everyday life it is usually necessary to carry out some single procedure.

It is for this reason that many home craftsmen decide to make a basic drilling machine with their own hands, using those parts and available materials that are available in any private garage.


As a rule, radio amateurs, as well as people who themselves perform simple household tasks, “light up” with the idea of ​​​​making a homemade mini-installation for drilling. renovation work. In some cases, a simple electric drill is sufficient for this. But, if we are talking about more serious procedures, the drill, of course, is not able to guarantee normal quality and accuracy of drilling. That’s when it makes sense to start making your own mini-machine, on which you can install different ones.

2 How to make a drilling machine from a drill?

Similar in home workshops drilling equipment occurs most often due to its simplicity self-made. You don't need materials high strength and any special devices. The mini hole drilling machine includes just four key components:

  • a bed that serves as the base of the machine;
  • rotation mechanism (in our case, its role is played by an electric drill);
  • feeder;
  • vertical stand.

The stand is usually made from ordinary chipboard or boards, since the small weight of the drill does not require the use of more durable materials. But it is better to make the bed as massive as possible. This will ensure the absence of vibrations during the drilling process, and therefore more comfortable work.

Experts advise using relatively thick (from 2 centimeters) material for the base of the unit. furniture board. The ideal option is to use an old photographic enlarger for the manufacture of the frame and stand. It will only need to be modified a little to really get reliable design mini-machine for household use.

Drilling quality and accuracy homemade unit depends on the correct connection of the frame and the vertical post. Therefore, this part of the work must be approached as responsibly as possible. It is recommended to cut two guides from steel strips, which are then connected to the stand with screws. The block with the drill will move along the indicated guides.

The block itself must be made so that it securely holds the electric drill. This is easy to achieve using small steel clamps. It is also advisable to place a small rubber spacer between the block and the drill. It will significantly reduce vibration and make the installation process more comfortable.

The feed mechanism of a drilling machine from a drill is a simple lever that will move the block with the tool in the vertical direction. This mechanism It is advisable to provide a spring with relatively high elasticity and power. One end of the spring should rest against a stationary wooden beam mounted on the stand, the other - against the block.

If you want to achieve maximum convenience in working with a home-made machine and do not plan to periodically remove the electric drill, it is recommended that you simply disassemble its switch and mount a separate button on the frame, with which you will start and turn off your drilling unit. As you can see, everything is quite simple. Any more or less handy man can make himself a small and convenient machine from a drill.

3 DIY drilling machine based on an asynchronous motor

Any owner in the garage, basement or somewhere on the balcony of the apartment stores many electric motors from electrical units that have served their useful life. From these, it is quite possible to choose a motor that will become the propulsion device for a mini-drilling machine. Ideal option in this case, an asynchronous type motor mounted on drum washing units is recognized.

The work of creating a home drilling rig based on an old electric motor is much more difficult than using a drill. But they can also be accomplished, armed with a certain amount of patience and perseverance. It is important to realize here that the motor from the washing machine has more serious weight. And the power of such a “motor” is much higher than that of an electric drill. This means that you will have to take care of preparing a “mighty” stand and base for the machine being created.

Experts say that the vibration level of a unit based on an asynchronous motor can be reduced by installing it on a powerful base, as well as by placing it closer to a vertical stand. But at the same time, it is necessary to remember that the close location of the rack and the motor is fraught with complications in the design of a homemade machine, which is caused by the need to install belt pulleys.

To make a drilling rig using an electric motor from a washing machine, among other things, you will need the following parts:

  • gear;
  • bearings in the amount of two pieces;
  • hexagon;
  • two tubes of small thickness (one of them must have an internal thread);
  • clamping ring (preferably made of durable material, such as tool steel).

A hexagon is required to make the moving part of the machine transmission device. A pulley will be put on it. You also need to attach a metal tube with a bearing and a steel ring to the hexagon. It is important to achieve a very tight connection of these components with each other, since otherwise they will completely collapse during vibration (not immediately, but quite quickly).

The adjustment complex of the unit is made of a gear and a tube on which cuts need to be made. They contain gear teeth. The specified tube is made of such a height that the drill chuck rises by a given amount. An axle with a hexagon is then pressed into the same tube.

From the described diagram it is clear that it is quite difficult to manufacture a machine with an asynchronous motor. Therefore, we can advise doing it by analogy with the previous process, when an electric drill was used. But be prepared for the fact that the resulting machine, unfortunately, will not be characterized by particularly accurate drilling.
