In a wide range of metalworking works, 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, or multifunctional multi-spindle machines with numerical control.

Homemade tabletop drilling machines

However, we will not be distracted by the description of all kinds of industrial drilling installations, especially since home handyman, 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 a simple homemade drilling machine, which can be assembled from scrap material at home, will interest every “handy” craftsman.

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

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

Of course, today any specialized store sells many models of various machines, including drilling machines, intended for use in home workshops. However, their cost is considerable, and not everyone can afford such a purchase, especially since if you have certain skills and desire, you can make a simple drilling machine yourself.

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

Let's consider in general outline manufacturing technology of each of these machines.

Drilling machine based on an electric drill

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

The weight of an electric drill is light, so to make a vertical stand you do not need any particularly durable 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 post or beam
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 your farm still has an old photographic enlarger for developing photographs, after a little modification it can be adapted as a base with a stand. If you don’t have anything that could be adapted as a frame with a stand, this element can be made from furniture board thickness of at least 20 mm.

When attaching the stand to the frame, it is extremely important to obtain a right angle, since the accuracy and quality of drilling will depend on this. Two guides cut from metal strips should be attached to the stand using screws, along which the block to which the drill is attached moves up and down. The block should be made in such a way that, using metal clamps you could clamp the drill tightly.

To reduce vibration, you can install between the body of the electric drill and the block rubber gasket. The vertical movement of the block with the drill is carried out using a lever. To ensure ease of operation, the feed mechanism should be equipped with a sufficiently powerful spring that could return 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 an on-off button directly on the frame.

Drilling machines based on asynchronous motor

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

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 mandatory installation of a power rack.

To reduce vibration, you should place the engine as close to the stand as possible or choose a fairly weighty, powerful frame.

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

To make the pulley structure you will need:

1. Hexagon
2. Steel clamp ring
3. Two bearings
4. Two pieces of thin tube, one of which with internal thread
5. Gear

The moving 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 placed.

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 attached to each other very tightly, otherwise the structure will begin to collapse from vibration.

To manufacture the machine's adjustment system, you will need a pipe with notches of the appropriate size and a gear, the teeth of which must freely penetrate into the notches on the pipe. In order not to make a mistake with the places of cuts on the pipe and their size, you should roll out plasticine on the pipe and move 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 the drill. The axle with a hexagon is pressed into a pipe with slots.

The design described above is quite complex to implement, and, let’s not lie, not everyone will be able to make it. Therefore, the easiest way, when manufacturing a machine with an asynchronous motor, is to select a powerful steel frame and assemble the machine by analogy with a unit with an electric drill. True, in any case, it will not be possible to completely avoid vibration, and you can count on getting holes especially exact size when using this unit it is not necessary.

Of course, this article indicates only general principles for making homemade drilling machines, and it cannot serve as a guide to action. Therefore, before you begin assembling the machine, it is recommended that you familiarize yourself with the drawings of various designs.

In addition, radio amateurs, who, as a rule, drill extremely small diameter holes 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, the microelectric motor will allow you to obtain almost ideal holes. An example of the construction of such a machine can be seen in the photo below.

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're talking about Regarding 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?

In home workshops, such drilling equipment is most often found due to its simplicity. self-made. You will not need high strength materials or 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 of 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.

Craftsmen advise using a relatively thick (from 2 centimeters) furniture board for the base of the unit. 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 holds securely 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. It is advisable to equip this mechanism with a spring of relatively high elasticity and power. One end of the spring should rest against a stationary device mounted on the stand. wooden beam, the other - into the block.

If you want to achieve maximum convenience in working with a homemade 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 unit for a mini-drilling machine. Ideal option in this case, an asynchronous type motor mounted on drum washing units is recognized.

Work on creating a home drilling machine using 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 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, it can be recommended to do 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.

A drilling machine is a unique device that is necessary for a home workshop. It allows you not to seek help from specialized workshops, but simply take and carry out the grooving work 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 scrap materials. There is nothing complicated in the process.

To make a home drilling machine, you only need an electric drill or a steering rack.

Purchasing industrial units will cost a pretty penny, so it is advisable to make your own model using drawings with dimensions, which are abundant on the Internet.

Before you begin creating the unit itself, you should complete the planning. This is a responsible step that requires a careful approach and drawing up a drawing. You need 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’s easy to make a mistake, and having a drawing will not allow you to make mistakes. People who neglect this stage in creating a drilling machine with their own hands overpay during the manufacturing process. What you need to take into account while working:

Drawings with dimensions.

• Length, width and height of equipment;
• Thickness of aggregates;
• Technical characteristics of electrical equipment;
• Data of the motor that will drive your machine;
• Power consumption;
• Grounding;
• Quantity of consumables.

The drawing will allow you not only to visually understand how to assemble the equipment, but also what it will exactly look like. The project will make it possible 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 main components. First of all, you should choose a bed for the filler machine. It will serve as a powerful foundation for a future grooving device.

After this, we decide on the rotation mechanism. It is better to choose an electric drill for it.

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

The third stage will be to select a device for supplying revolutions

on the working part of the drill, and also decide on 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 absorb the rattling of the drill itself. To prevent vibrations from affecting the equipment and the accuracy of work, it is best to select strong metals. Very good, an old stand from a photo enlarger will work 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 stand and the unit frame.

The home lathe maker will also need to use several strips of steel to cut two guide bars. They will help to move the block on which the drill is located. You can use screws to secure them. We take and screw everything to the rack.

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

The basis of the movement of the machine is the lever. It allows you to easily move the block with an electric drill in a vertical position. A spring will be installed there, which will allow the drilling apparatus to be maintained at the required tension.

Selecting 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.

If you are going to buy it new from the manufacturer, prepare a tidy sum,

because it is not cheap at all. More profitable solution- is to choose a used part, best from a VAZ 2108.

Advice: As soon as you have purchased such a spare part, you should carefully inspect it, carry out preventive maintenance and repairs if necessary. This will give it a smoother ride when working with the drilling machine.

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

1. To make the body you will need to use a drill along with a column. All this should be installed on a table, which will serve as a platform for the future drilling machine. The table dimensions 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 should first select a U-shaped steel profile with dimensions 30x60x30. Then you need to weld it to metal sheet with a thickness of 2 mm. In theory, the stand itself should be 6-7 cm taller than the length of the column itself.
4. When creating equipment, it is best for the machine operator to use the VAZ 2108 steering rack, which was mentioned earlier, as the stroke of the rod.
5. To further increase the rigidity of the entire structure, additional ribs should be installed during installation.

To ensure that the operator does not have problems starting or shutting down equipment during operation, you should consider practical system starting and stopping the drilling machine motor.

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

To make it, the creator will need:

• Micromotor or engine operating at high speeds.
• Special collet for clamping small drills.
• Several wooden blocks.
• U-shaped metal profile.
• A retaining ring that will help secure the engine.
• A mobile platform for a machine, which is created with your own hands from all kinds of materials found in everyday life.

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

If the motor becomes distorted under some circumstances, the user runs the risk of damaging the drills. During the production of home drilling equipment, you need to carefully monitor the quality of the motor fixation. If it is not installed securely, it will simply be torn out of the frame when the engine is running at high speeds. This is fraught with damage to your property and the risk of harm to health.

How to make a coordinate table

IN home machine For drilling, the role of the coordinate table will be performed 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 required by the user number of axes. 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, you cannot do without using several linear-type modules. They must be made of aluminum profile.

To carry out motion transfer when creating milling table A special toothed rack should be used, as well as a reinforced belt. Instead, a ball-screw element will do just fine.

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

Important! When creating a router table for your drill press, be sure to make a drawing before you begin. 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 technical characteristics the drilling unit itself. The design itself can be either lightweight or with increased strength. And also 2 or 3 coordinates can be used there. The first step before creating a machine is to understand its main role in your home workshop. And this can be used as a starting point in the design and further production process.

When everything is ready, you need to make a vice, otherwise you will not be able to fix the part at home; holding it in your hands is strictly prohibited. Purchasing old Soviet vices made of steel or cast iron can be expensive. Models made in China, not everyone will like it due to its fragility. Therefore one of economical options will make them yourself.

You will need:

• A screw with a 2 cm thread 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 stationary sponge. How to make this element? To create, use pine wood. It is affordable and quite durable. The board should be grafted onto the tabletop.

To make the mobile part of the vice 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 you need to do is cut holes with a diameter of 2.1 cm. In studs, this diameter will be 1 cm. Then the creator simply inserts the studs along with the screws into the finished holes, after which he attaches the nuts and tightens them with bolts.

And this concludes the production of home vices.

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

Plug the engine into the outlet and, if you did everything correctly, it didn’t happen to you. short circuit, there are no uncharacteristic sounds for the operation of the unit - 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.

Video on how to make a drilling machine

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

You can buy the most popular herbicides for corn in Ukraine on the website www.pol.ua

Construction stores offer us a huge range of different drilling machines in all price categories.

However, the cost of a really high-quality model hits your pocket hard, and there is no point in purchasing a cheap drilling machine from consumer Chinese manufacturers, the service life of which is ridiculous.

It is much easier to buy a good electric drill and use it to make a hand-held desktop homemade drilling machine that will fully meet all your requirements.

The cost of a high-quality drill is much less than that of full-fledged drilling machines.

In addition, you can use an electric drill that is already on the farm, since the design of the machine allows for its quick dismantling, which allows you to use one drill both in stationary and manual mode.

1 Required tools and materials

A tabletop drilling machine can be made from a drill using metal pipes or wooden parts. We recommend that you give preference to the second option, since it is much less labor-intensive and does not require the use of either an angle grinder or a welding machine.

Wood homemade machine has strength, which is more than enough for normal household use.

You can make such a machine yourself, based on a drill, by following all the recommendations described below, with your own hands within two hours, and it will serve you for many years.

In order to make a tabletop drilling machine with your own hands, you will need the following materials:

• wooden boards 2-2.5 centimeters thick;
• guide metal slats - 2 pieces (such slats are used for feeding drawers in tables and chests of drawers, they can be purchased at any furniture supermarket);
• wooden beam measuring 20*30 mm - about two meters;
• wood screws 20 and 30 millimeters long;
• wood glue;
• electric drill;
• metal rod with M8 thread;
• metal tube with M6 class thread;
• screws and nuts.

The actual work is carried out using the following tools:

• screwdriver (Phillips or regular, depending on what screws you will use);
• drill;
• sandpaper;
• jigsaw and hacksaw;
• corner;
• pencil, ruler;
• level
• roulette
• carpentry clamps for fixing boards.

1.1 Creating a base for the frame

To create a basic base for a homemade drilling machine, use a hacksaw to cut a 20*30 wooden beam into four pieces, two of which are 17 centimeters long, and two more are 20 centimeters long.

If you want to create a homemade machine based on a massive electric drill, then it would be better to make a larger base, since increasing its size will give the structure greater stability.

Next, prepare a board with dimensions of 200*220*20 millimeters (dimensions are based on the above dimensions of the timber). Using self-tapping screws, connect the beam sections into one frame. To connect at each end of the beam, you need to use two self-tapping screws; if you are using a thicker beam, you can screw in a self-tapping screw at each end corner.

Place a board on top of the resulting frame. Screw it with self-tapping screws around the perimeter of the beam; 2-3 bolts on one side will be more than enough.

To make your work easier, it is recommended Drill preliminary holes in the boards, into which it is much easier to screw self-tapping screws than into a solid board. To avoid protrusions of screw heads above wooden surface You can use a larger diameter drill to chamfer under their heads.

1.2 Creating a column for guides

The width of the board for the column must correspond to the width of the created base, the thickness is 20 mm, and the height is determined depending on the size of the drill used, as a rule, a height of 40-50 centimeters will be more than enough. An excessively high column can negatively affect the stability of the entire structure.

Once you have cut the board to the appropriate size, immediately attach it to the base using self-tapping screws. Next you need to arrange free space between the column itself and the electric drill, to do this, attach two pieces of timber, measuring 25*35*17 millimeters, in the center of the upper part of the column parallel to each other.

To avoid making a mistake with the installation location, make preliminary markings. Draw a straight line from the center point of the top of the column down, then step back 50 mm on each side and draw two lines parallel to each other. The distance between the lines should be 100 mm.

Pay close attention to so that the lines are strictly parallel to each other, so even the slightest angle of inclination of the trajectory along which the guides move risks the fact that the drill will not enter the surface being processed at a right angle, which is why when drilling hard metal surfaces, thin drills will break very quickly .

1.3 Installation of guides

Installing guides is perhaps the most difficult part of creating a drilling machine with your own hands. It is extremely important that the guides run exactly perpendicular to the base of the machine and parallel to each other.

Prepare two boards measuring 100*250*20 mm, and mark on them the places where the retractable slats will be attached. Retractable slats sold in furniture stores are already equipped with holes for self-tapping screws, so All you have to do is screw them to the guides with your own hands. After the slats are attached, we mount the guides on the column.

1.4 Creating mounts for a drill

We suggest you make a universal mount with your own hands, which is suitable for installing not only a mini-drill, but also a full-fledged electric drill. To do this, prepare a board with dimensions 60*100*20 for the upper holder, and 100*100*20 for the lower one.

Use a jigsaw to cut a hole in the center of the bottom board, the diameter of which is suitable for securely fixing your drill. Secure it to the guide using a furniture corner and self-tapping screws.

We also cut out the top holder using jigsaws. Its size and shape are individual and depend on what shape of drill you will use. We make holes around the perimeter of both clamps and screw in screws that will clamp and firmly fix the drill in the holder.

2 Making a height limiter

A height limiter is necessary so that a homemade drilling machine can make multiple holes of identical depth. Perfect for creating a limiter metal rod with M8 thread.

Drill a hole in the base in which the rod will be installed (it should be tightly fixed in the base, but at the same time rotate freely).

Next, we cut out a small piece of timber, drill a hole in it and install a threaded sleeve on one side, and a piece of rod that will limit the amplitude of movement of the guides on the other. We screw the beam onto the main rod.

For manual tabletop drilling the machine was more convenient to use, You need to make a handle on the restrictive rod.

This can be an ordinary homemade plywood stop, which is fixedly fixed between two nuts.

2.1 Making a homemade drilling machine (video)

In order to save time, you can buy a ready-made inexpensive stand and vice for a drill in the OBI.RU store, which allows you to fix the drill in a vertical position and use it as a drilling machine, thereby increasing the accuracy and speed of work.

Characteristics:

• height: 400 mm;
• clamping hole diameter: 43 mm;
• drilling depth: 60 mm;
• The kit includes a vice for fixing workpieces.

A drilling machine made from a drill is a special device that simplifies the process of creating holes in metal, wood, and plastic of various configurations.

To save money without losing the quality of the result, you can make a drill press from a drill yourself, using simple and basic tools.

What is a drilling machine?

A homemade drilling machine from a drill is required for those people who often do drilling.

Unlike conventional, manual drilling, in which the drill is not secured, drilling with an improved device allows you to get a better result.

Drilling machine from hand drill It can have both compact dimensions suitable for desktop installation, and more substantial parameters that turn it into a floor-standing machine.

Professional drilling machines, which are sold in specialized construction stores, are of great value.

As a rule, device models of this plan are equipped with several work zones and often software control, which increases the productivity of the equipment.

For “home” use, the use of advanced machines is often impractical.

Therefore, many people, faced with the need to purchase a drilling machine to perform simple operations, prefer to make it themselves.

How to make your own high-quality drilling machine from scrap materials that can easily cope with the responsibilities assigned to it and is designed to work with various materials?

Before you begin manufacturing the machine, you should study the drawings and accompanying information, which will allow you to understand the structure of the device in more depth.

Advantages of a drilling machine made from a drill, made by yourself:

• minimal cash costs for purchasing parts;
• compact dimensions allowing the device to be transported from place to place;
• high precision of the work performed;
• possibility of using drills of different diameters, etc.

In order for the drilling carried out using the assembled device to be of high quality, care should be taken to create a truly thoughtful model.

A properly assembled drilling machine should consist of the following parts:

• stands that will serve as a support for installing objects;
• a rotating mechanism that starts the drill;
• a device that supplies electricity;
• vertical stand supporting the weight of the working device.

In everyday life, the role of a rotating mechanism is often played by a conventional drill with a suitable configuration.

It can be securely attached to the machine, making the design of the device “monolithic,” or it can be used as a removable element that is installed immediately before work.

Making a drilling machine from a household drill

The horizontal support, called the frame, can be made from an ordinary wooden slab, the thickness of which ranges from twenty to fifty millimeters.

As alternative material You can use a thick sheet of fiberboard or chipboard, a base from an unused photo enlarger, etc.

Some craftsmen make drilling machine frames using parts from old Soviet microscopes.

It is worth noting that the drilling machine installed on the base of this device will only be suitable for working with small parts.

The material for the stand that supports the weight of the structure can be chipboard sheet or wooden beam(it is better to select a block with dimensions of five by five centimeters).

The larger the area and thickness of the bed, the less vibration the machine will produce during operation. The less vibration, the higher the drilling accuracy.

Vibration can be minimized by securely fastening the stand and frame.

The strength of the structure can be increased by additionally treating the joints of all static components of the machine with glue suitable for these materials.

To expand the operating capabilities of a homemade drilling machine, you should install a pair of wooden (or metal) guides on the stand along which you can move the drill holder.

As a drill holder (or, in other words, a block), you can use a steel clamp equipped with a locking mechanism.

Thanks to it, it will be convenient to attach the drill to the machine before work and take it out as needed.

You can further reduce the level of vibration that occurs during operation of the machine by protecting the joints between the drill body and the steel clamp with a special insulating gasket made of rubber.

The mechanism that will ensure the vertical movement of the drill body must be equipped with a lever and a spring attached to a stand and a block.

To form this mechanism It is better to use high-quality springs with a large diameter and high rigidity.

If you own several drills, then use one of them as a permanent working device for the drilling machine.

When manufacturing a capital device that will be equipped with a permanent drill, it makes sense to move the drill power button to the machine body, disassembling the device’s on/off switch and extending the necessary wires.

It will be easier to work with an “improved” mechanism, the turning on and off of which is easier to control.

Creating an asynchronous drilling machine

How to make an asynchronous drilling-type additive machine using available materials?

This question is asked by many people who want to expand the functionality of the devices they use.

To make an asynchronous type drilling machine, it is not necessary to use an electric drill.

A mechanism that will create holes required diameter in selected materials, can be created by including any electric motor with suitable power in the chain of working elements.

You can find electric motors in specialized stores, or you can disassemble the old household appliances, which has fairly large parameters.

Ideally, an asynchronous drilling machine will be made on the basis of an engine that previously started a household washing machine.

It is worth paying attention to the fact that for this part you should select a rack and frame of the required density and correct sizes to intelligently distribute the weight of their overall structure.

The engine will act as an asynchronous machine, powered by electric alternating current and having an unequal rotor speed.

The level of vibration that occurs during operation of an asynchronous machine can be reduced by installing the motor on a thick base, placing it in minimum distance from the counter.

The space between the base and the stand must be suitable for the free movement of the belt responsible for starting the drilling head (when the motor rotates).

Materials and mechanisms that should be used when creating an asynchronous drilling machine:

• a reliable frame and stand made of wood;
• metal guides;
• gears and hexagons designed to fix the pulley;
• bearings of the required diameter;
• two metal pipes (hollow and equipped with external thread);
• steel clamp.

Assembling the device should begin by connecting a hollow metal pipe, a hexagon and a clamping ring.

It is important to ensure that there are no gaps at the junction of these devices.

Then you should file the second one metal pipe, forming a homemade carving on its body. The height of the pipe used must be suitable for subsequent press-in of the hexagon axle.

After everything preparatory work will be completed, the device should be assembled and its operation tested on “rough” materials.

If a device equipped with an asynchronous motor does not work correctly, it should be sorted out and the problems sorted out before putting it into serious operation.

At home, to create holes in metal, wood or plastic, it is better to use a simple drilling machine made on the basis of a conventional electric drill.

Make this device Any beginner who is familiar only with basic knowledge in the construction business can do it.

Today we will tell you why you need an impact drill and how it works.

A conventional drill produces only rotational movements, thanks to which it is capable of drilling wood, plastic or even metal. But what if you need to drill into concrete or brick?

Create a drilling machine from a drill with your own hands, drawings to help!

Concrete and brick are durable materials and regular drill when rotated, it simply does not go deep into them, but at the same time, concrete and brick crumble upon impact.

Impact drill uses this feature, it is capable of not only performing rotational movements, but also simultaneously translational (shock movements). Let's take a closer look at the operating principle of an impact drill.

The impact drill can operate in regular drill, i.e. only in drilling mode. In this case, the motor spindle simply transmits rotational movements to the main gear of the gearbox, which is connected to the chuck. The drill usually rotates.

If you turn on the impact mode, then a second ratchet, which is rigidly fixed to the drill body, will move to the ratchet (a flat gear with oblique teeth) on the main gear. When the motor spindle rotates, the oblique teeth of the ratchets repel each other. The main gear together with the shaft (as well as the chuck with attached equipment) makes translational movements along the axis. This is how shock mode works.

In impact mode, you need to use pobedit drills.

Disadvantages of an Impact Drill

This operating principle is fraught with several disadvantages. Firstly, the amplitude of movement of the drill along the axis is quite small, which reduces the effectiveness of the impact mode. Secondly, the force of the impact directly depends on the force of pressure on the drill itself, i.e. The harder you press on the drill, the more the drill crumbles the concrete. When working with an impact drill, your hands get tired pretty quickly. Thirdly, the impact drill mechanism is quite short-lived. The ratchet parts wear out over time and the drill turns from an impact drill into a regular one. Therefore, it is recommended to use the shock mode occasionally. If you constantly work with concrete, then it is better to buy a hammer drill.

You should not use an impact drill with concrete grade higher than 300.

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.

Homemade machine based on an electric drill

We will take an ordinary electric drill as the basis for our future machine. This tool differs in low weight. This suggests that we do not have to use structures made of durable metals. Ordinary wooden boards or even chipboard are 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 search carefully - in household You'll likely find a wide variety of electric motors 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 complicated. 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 pulley, we need a gear, a hexagon, a metal ring for clamping, 2 bearings and 2 pieces of pipe, one of which is with an 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. 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
