Do-it-yourself homemade drilling machines. Create a drilling machine from a drill with your own hands, drawings to help! What can be done with a drilling machine

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

In the workshops of radio amateurs, mini machines homemade 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.

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

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

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

Drilling unit from a drill

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

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

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

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

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

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

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

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

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

Between the drill and the shoe is placed rubber gasket in order to reduce the vibration of the mini drilling machine.

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

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

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

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

Steering rack for drilling machine

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

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

Instructions for the manufacture of the bed and its installation:

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

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

To supplement the theme will allow thematic video material.

PCB Drilling Machine

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

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

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

The video below shows a mini PCB drilling machine.

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

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

Coordinate table design

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

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

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

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

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, first make drawings, calculate and select components.

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

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

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

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

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

Homemade vice for machine tools

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

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

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

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

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

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

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

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 our own hands, since this topic is more than relevant.

Buying a factory model, even if it is a used vehicle, requires a lot of money family budget. We will tell you how to assemble a metal drilling machine from improvised means with minimal investment.

To date, there are 2 proven designs that are easy to assemble in "garage" conditions.

This is a machine tool 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.

We will take an ordinary electric drill as the basis of our future machine.

This tool is lightweight. This suggests that we do not have to use structures made of strong 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 feeder. The choice of the base of the machine (bed) is a very crucial moment, since the intensity of vibrations during operation will depend on the strength and massiveness of this design.

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

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

After some manipulations, it is easy to turn it into a full-fledged basis for a homemade drilling machine. If you could not find a photographic enlarger even on the used equipment market, you can replace this element with an ordinary design from a 20 mm furniture plate. It will provide sufficient rigidity for precise work.

In the process of fixing the bed on the rack, it is very important that a perfectly right angle be maintained between them.

This will increase the accuracy of drilling.

It is necessary to fix two guides on the rack, which can be made from ordinary metal strips. The block with the drill fixed on it by means of clamps will move along the guides. For additional vibration isolation of the tool, it makes sense to put a rubber gasket between the electric drill and the shoe.

The 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 the block on one side, and on the fixed beam on the other.

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 place convenient for you.

That, in fact, is all.

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 the household you will most likely find a 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 the assembly of such a machine will be somewhat more difficult.

First of all, you will need a more massive rack that will absorb significant vibrations from the motor. washing machine. To minimize them, 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 the pulley with the transmission. When assembling such a unit, adjust all parts and assemblies as accurately as possible.

The performance of the machine will directly depend on this.

To assemble the pulleys, we need a gear, a hexagon, a metal ring for clamping, 2 bearings and 2 pipe cuts, 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 on which the pulley is put on.

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

Make sure that all the details of our construction are fixed as securely as possible in order to avoid destruction due to vibrations.

Now let's start creating the adjustment system of our unit.

DIY 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 a gear over it. Please note that the ladder pipe must have a height corresponding to the height of the cartridge. The hexagon axle must be pressed into the pre-slotted pipe.

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

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 brought two of the most good examples manufacture of drilling machines with their own hands.

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

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

It remains only to wish you good luck.

Metal drilling

Types of drilling machines and their purpose

Drilling is understood as a method of shaping internal cylindrical surfaces in a solid workpiece material using a drill.

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

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

Drilling machines are divided into the 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 widely used.

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

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

1, a vertical drilling machine of aggregate layout is shown. A hollow column is installed on its foundation slab.

On its vertical guides manually (handwheel 2) move the table on which the workpiece is installed. The spindle is mounted in the drilling head and is subject to rotational and vertical rectilinear translational motion. The latter is carried out manually (handwheel 5) or automatically.

A cutting tool is installed in the spindle. In the drilling head there are drive mechanisms for the rotational and translational movement of the spindle, an electric motor and machine control mechanisms. The drilling head can be manually moved along the vertical guides of the column. The required mutual position of the drilling head and the table is set (taking into account the dimensions of the workpiece) before the start of processing, after which this position is fixed.

Inside the column 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 start 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, the processing of large-sized heavy workpieces with a large number of holes on vertical drilling machines is associated with significant labor and time costs.

In order to avoid these costs for 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 place.

The radial drilling machine consists of a base plate on which a pedestal with a fixed column is installed. A sleeve is put on it, which can rotate 360 ​​° relative to the column.

On the sleeve, as on a guide, the sleeve moves (with the help of a special drive) in the vertical direction, along the horizontal guides of which the drilling head moves.

Gearboxes and feeds 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 own axis and move in the vertical direction. The workpiece is installed on the table 8 or directly on the foundation plate.

Before starting processing, 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 nodes are fixed using appropriate mechanisms located in the lower part of the sleeve, above the pedestal and in the drilling head. Then turn on the rotation of the spindle, its vertical feed and produce processing.

How to assemble homemade drilling machines?

In modern production, the use of various machine tools has become so popular that now not a single decent workshop can do without this equipment.

And indeed, the machine allows a person to engage in the performance of such work, which he independently completes, if he can, then with the use of 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 plus of the machines is that their manufacture is not difficult.

Homemade drilling machine from a finished drill

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

It is about the assembly of home-made drilling machines that will now be discussed in this article.

Features and purpose

Machine tools are widely used in industry.

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

Indeed, the presence of machine tools in production is a real blessing. A high-quality drilling and grooving unit is able to perform work with amazing accuracy, while reducing the requirements for the original skills of a person that uses it in work.

This phenomenon is explained very easily.

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

Holes should be of different diameters. From the smallest to the largest. The plate at the same time has a thickness of 3-5 mm. That is, for working on metal, you will have to use a fairly powerful drill.

Note that large drills are used by large tools, such drills are usually quite heavy.

It will be difficult for an unprepared person to even hold them in their hands. Not to mention the performance of more or less lengthy work.

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

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

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

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

When drilling boards, this time cost can double.

And this is the case if you have experience and relevant skills.

If it is not there, then it can literally take a whole day to prepare only one plate.

Homemade machine of high build quality

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

The drill is stable and clearly directed.

All that is required of you is to correctly install the plate on the XY table, start the engine and drill a hole. Then change the position of the part and continue working on the same technology. As you can see, the productivity of production is reaching a qualitatively new level.

Components of the machine

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 figure out the details that will be used when assembling it.

Fortunately, a homemade drilling machine consists of several basic parts.

Their quality determines the quality of the device itself, but it all depends on many factors.

So, the drilling machine consists of:

• Beds or bases;
• Fixing rails or frames;
• The mechanism for regulating the position of the device;
• Fastenings for the working mechanism;
• An engine or mechanism that directly performs drilling;
• Adapters, collets and other similar materials;
• All kinds of handles, stabilizing legs and other additional details that are used to improve the design of the device.

It is worth noting that it practically does not matter whether you are considering a PCB machine or a standard stationary sample.

You will of course use miscellaneous details to assemble a homemade drilling machine, however general scheme will remain the same.

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

Using an old table as a machine bed

For example, a home-made desktop unit for drilling boards for electronics will be mounted on a shallow frame. In most cases, you won't even need a cabinet. It will be enough to take a large heavy rail, which by its weight will be at least half the design of the device.

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

Selection of parts for assembly

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

The base for an impressive machine must be very strong and stable. It is necessary for such purposes to use a table with good supports, special stands, etc. Even a nightstand will do the right sizes and dimensions, 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 bed can be made from a metal plate or something similar.

Interestingly, some craftsmen manage to assemble a table or a frame for a machine tool even from the ancient parts of a photographic enlarger. That is, a wide variety of details can be used in the work.

The main thing is that the table or bed on which the device is attached is extremely stable and does not give vibrations during operation.

You can make a frame for fastening with your own hands.

The same is done with the mount for the working mechanism. Here you can use metal corner With drilled holes or something similar.

The corner is fixed to the table with screws or welded to the frame. Installed there lifting mechanism. It is made from an old jack, shock-absorbing pipe, sliding rails and other similar mechanisms.

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

Moreover, the table and the base of the machine must withstand its weight without any problems and dampen vibrations during operation.

Benchtop drilling machine with spring dampers

A good fit 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 you can quickly assemble with your own hands. Then the standard scheme for assembling drilling equipment 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 consists in using a ready-made drill, which is simply screwed to the mounts.

The second is a rather complicated option, and it consists in assembling the machine from a separate engine, collets, guides, etc.

1. We collect the table and the base for the machine, we are engaged in fixing the bed.
2. We mount the main stabilizing frame.
3. We connect the mount for the engine.
4. We are in the process of building a lift.
5. If necessary, install springs and shock absorbers.
6. We mount the working element of the machine.
7. We connect all the contacts, install the drill.

When assembling the machine from a finished drill, it will be easier for you to work.

All that is required of you is to create a strong frame with the ability to raise and lower the drilling mechanism, to which the drill will then be connected.

There is no need to mess around with power supplies and engine assembly. You just need to properly fix the tool and connect it to electricity.

The assembly of the engine already provides for the installation of a power supply, a converter, and, if the engine has an indirect transmission of forces, mechanisms that are involved in their transmission.

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

Yes, and certain engineering skills will not be superfluous either.

Most often, ordinary drills are used for drilling work, since drilling work is not particularly difficult. Therefore, in most cases, home craftsmen do not need drilling machines. Such units are especially popular among radio amateurs. However, even those who practice frequently repair work, may be interested in the drilling device. Buying industrial drilling machines and using them in everyday life is expensive. The problem can be solved quite simply. To do this, you only need to make a drilling machine with your own hands.

Drilling machine: working principle

Often there are situations in which a manual or electric drill is not able to complete the task. So, for example, for the manufacture of printed circuit boards, it is necessary to drill a lot of holes with a small diameter of 0.5-1 mm. It is not very convenient to perform such work with a drill, in addition, the drill may break.

With such work, a home-made mini-drilling machine can help out.

The design of the machine for drilling

Despite the fact that the design of the unit seems complicated, it consists of only four parts.

The main parts of the drilling machine:

• engine;
• transmission mechanism;
• working body;
• government.

In such a device, an electric motor using a transmission mechanism transmits movement to the working body, which is the drill. The working body is mounted in a cartridge, which is mounted on a rotating shaft (spindle).

The rotation is transmitted to the spindle by means of a belt drive. Using rack and pinion, the drill chuck can be raised and lowered by turning the handle.

The control unit of the unit is located on the front panel of the machine, on which there are buttons for turning on and off the electric motor. Depending on the required direction of rotation of the drill, the machine is turned on using any of the extreme buttons. You can turn off the device by pressing the middle red button.

A vertical screw-column is fixedly mounted to the base of the equipment. One of the handles is used to move the headstock around it. With the help of the second handle, the headstock is fixed in the desired position. Machines are equipped with a special scale, which reflects the depth of blind holes.

The drilling speed is set depending on what material the workpiece has. To do this, it is transferred to a pulley of a certain diameter belt drive belt, and a certain spindle speed is set.

The described design of the machine is one of the simplest. In production, drilling units with more complex schemes are most often installed.

Instructions for the manufacture of a drilling machine

Proposed homemade device can easily and with minimal effort drill holes at high speed. In this case, the depth of the holes made will be the same. In addition, it will be possible to adjust the position of the tool in the unit, so that it will be able to cut perfectly even squares from wood.

For the manufacture of homemade machine need to prepare:

First of all, with your own hands you need to make base of the future drilling unit.

1. Cut out the main plate rectangular shape and four bars.
2. Attach the bars adjusted to its size to the edges of the form.
3. Fix the structure with clamps.
4. Stepping back from the edge of 1 cm, mark with a pencil the location of the screws, and drill.
5. Lubricate the attachment points of the base and bars with glue, connect the elements and fasten with self-tapping screws.

After the glue is completely dry, the clamps will need to be removed. The base is ready, now it follows start doing the hand of the machine.

1. On a rectangular board 40 cm long, it is necessary to make markings. To do this, along the base you need to draw a center line and step back from it in each direction by 5 cm.
2. At the marked distance, it will be necessary to attach the bars, each of which should be 17 cm long.
3. Attach the bars according to the markup and screw in the center with self-tapping screws.

For a more reliable connection, the elements can be pre-lubricated with glue.

At the next stage in the manufacture of a drilling machine, the most difficult part of the unit is performed by one's own hands, namely, its moving element. For its manufacture are taken two planks 25 cm long and guides.

The components of the structure are ready. All their lines, surfaces and angles must be even. Now the sleeve must be laid on a flat surface, and the base of the machine must be installed perpendicularly, and connected with a clamp. If a right angle is obtained, then the line of attachment of the sleeve and the base is marked, after which the parts are connected with self-tapping screws.

As a support for the drill will serve another plank of wood, which should be square. In its middle, you will first need to cut a circle, and then use the L-shaped brackets to attach the bar to the machine.

To make the support bar universal, you need to cut small square holes on four sides inside the circle, and drill longitudinal holes on the outside in the same places. After that, screws are inserted into them, with which you can securely fix a drill of any size.

To make the drill stable during work, the upper part of the support is made from another bar. To do this, a circle is cut out, and a part of the plank is cut off on one side. The rest is bolted to the moving structure.

The last element to be installed in the machine is the stopper. It will be needed so that when drilling you can change hole depth.

A long threaded rod will serve as a stopper, under which a hole is drilled in the base of the structure. Then two holes are made in a small block of wood, one of which should be located horizontally and the other vertically. A screw will need to be screwed into the horizontal hole, part of which should come out on the other side. A screw plug is simply inserted into the vertical hole.

Now the bar must be installed between the movable installation and the base into which the long rod should be inserted. Having passed the rod through the screw plug, it must be tightened to the end.

Works on the manufacture of the drilling machine are completed. The device is ready for the drilling process.

Drilling machine based on asynchronous motor

You can create with your own hands electric motor machine from any unit that has served its time. Such a motor will become the mover for a mini-drilling machine. Best Option the engine is considered from drum washing units.

Since the engine from the washing machine has big weight, and its power is higher than that of an electric drill, it will be necessary to prepare a powerful stand and base for it.

In order for the engine to vibrate as little as possible, it is placed as close to the rack as possible. In this case, it is necessary to additionally install pulleys with a belt drive.

For the manufacture of construction pulleys you need to prepare:

• hexagon;
• two bearings;
• gear;
• clamping ring made of durable steel;
• two tubes of small thickness, one of which must be with an internal thread.

To make the movable part of the transmission device of the unit, put a pulley on the hexagon and attach a metal tube with a steel ring and bearing. These elements must be tightly connected to each other, otherwise they will collapse very quickly under the influence of vibration.

The adjustment complex of the device is made from a tube with notches and a gear. The tube must be of such length that the cartridge can rise to the desired height. An axis with a hexagon is pressed into it.

It is quite difficult to make the described design with your own hands. For easier execution, it is recommended to assemble it by analogy with a machine tool with an electric drill. It is also worth noting that it will not work to achieve the exact size of the holes using such a unit.

Do-it-yourself work on creating a homemade drilling machine requires patience and perseverance. But those home craftsmen who really need such a unit will be satisfied with the result.

Amateur radio is a multifaceted occupation, for some it’s a simple repetition of other people’s schemes, for moral satisfaction, for some it’s a sport, for some it’s development intellectual abilities, and to whom it is creativity, the embodiment of ideas and designs, self-affirmation. But be that as it may, this process is closely related to the mechanical perforation of foil material, whether it be textolite, getinaks or fluoroplast. Of course, our (and Chinese) industry produces a lot of products that can make 1-2 holes before a breakdown, but we, radio amateurs, are creative people, and we will not get hung up on other people's buzzers and buzzers, but we will try to make our own, which is warmer to the soul and works more reliably . However, the question arises, what to do? And on what? Not every radio amateur has a workshop stuffed with machine tools and materials at hand, and the specialists have now become different, you can’t get off with a bottle.

But it was a saying, now in fact. Faced with the aforementioned problem, the idea arose to assemble such a drilling machine that can be made even without special tools. It’s not that there was nothing to drill with - I’ve been drilling for a long time, about 30 years ago, I tried a lot of hand drills, but when I was faced with the need to make an adapter board with many sockets, I decided to make a machine that would greatly simplify and speed up this business. The first thing that came to mind was to google the Internet. For almost a week on slow traffic I leafed through what I found, but I didn’t come across anything suitable, or rather I came across a lot, but one didn’t suit me because of the need to break the microscope, which, moreover, didn’t exist yet, the other is too primitive, the third requires special equipment.

Here, for example, is a machine that I liked in terms of design, but frightening with the complexity of manufacturing. Having seen enough of other people's designs, I decided to connect the brain bone and do something from available materials. In general, let me bring to your attention an amateur radio drilling machine with, available for repetition with minimal experience in assembling such devices.

Drill stand

First of all, the bed, the basis of any machine. It must be strong and stable. The choice fell on iron. there was none, I had to ask for a piece in the workshop. The guide rod was used from a failed printer. Slightly trimmed with a "grinder", welded to the bed through a hole drilled in advance. To reduce friction, I used bushings from the same printer, but this is not necessary.

So, the first thing that caught my eye, found once on scrap metal (then they didn’t sweep so carefully) an duralumin panel, 8 mm thick from some kind of disassembled device, suited me, but it was necessary to cut it into narrow strips. I loaded a new blade into a hacksaw for metal, an oiler, so that the teeth would not clog and forward, sawed the strips, first of all folding the upper and lower strips and clamping them firmly in a vise, drilled holes for the rod. then, inserting the rest of the rod into this hole (so that there is no displacement), I drilled the remaining holes.

The next step was to insert the cross brace, drill holes in it and cut the threads. Having fastened the upper, lower slats and the transverse strut with screws through the regular holes, we proceed to the longitudinal strut. We drill it in the same way as the transverse one, in place through the existing holes in the slats. We look and do the rest, according to the drawings.

I want to note that it is not necessary to use the materials that I used. Several of my friends repeated this design using plex, iron rod for welding, and even wood, and it all worked out great. I’ll also add for accuracy, the return spring was used from a desoldering pump, and the backlight was from an LED flashlight key fob.

Electric motor for drilling machine

We finished with the mechanics, now the heart of any machine is a fiery motor. In my design, it is called DPM30-n1-19, but in principle it does not matter, others can be used. We will not heat it up to the flame, so we will use the speed controller. Here I will not give advice, how many people, how many opinions. Some people like to drill, so that with a constant moment, others - with a stop for "aiming", others somehow. At first, I was also a supporter of putting the drill at the drilling point and then turning it on smoothly. Convenient and accurate if you drill by hand. But we have a machine. At first I tried without a regulator, at a stable speed. If the drill "beats" a little, the picture is deplorable. But drills, they are what they are, sometimes you don’t have to choose, so I decided to try the scheme that I found on one radio site, with positive feedback.

The essence of the process is that when there is no load on the drill, it rotates at a low speed (about 300 rpm), and when you press it, the load on the drill increases and the maximum speed is turned on. This method of management seemed to me (and not only) the most effective. Printed circuit board has been redesigned to fit.

Any power source of suitable power and voltage can be used to power the device. I used a power supply from the same printer, modified a little so that the output voltage could be changed. It can then be used to connect, say, a soldering iron or other devices, for more full use IP. Video demonstration of the device:

After the demonstration on youtube, Semenchuk Viktor Stepanovich contacted me by e-mail with a proposal to make high-quality drawings in Compass in exchange for freehand drawings with dimensions, which I did, thank you very much for this. File to PDF. The file in Compas format can be obtained from the author (Viktor Stepanovich) or from me :)

I hope my simple design both radio amateurs and the administration of Technoobzor will like it :) Ask questions on the forum. Sincerely, Oleg63m.

For household chores, the functions of a drill may be sufficient, but more precise equipment may be needed to improve the quality and productivity of work. One of the most popular varieties is a do-it-yourself mini-drilling machine.

Drilling machine components

The first stage before production is to study the design. To do this, it is recommended to take a drawing of a standard machine and familiarize yourself with its components. Important to understand general principle functioning and in the future to determine the optimal scheme of a self-made design.

Main functional purpose is to form holes various types. Depending on the configuration of the equipment, there may be drawings of vertical drilling, jig boring, radial drilling, filler models. The difference between them lies in the possibility of changing the direction of action of the cutting tool. For domestic needs, a vertical drilling mini-machine is most often made by hand.

Structurally, it should consist of the following elements:

• bed. The supporting part on which the vertical rack is attached;
• rack. Designed for installation of electrical equipment;
• electrical components. They include an electric motor and a mechanism for transmitting torque to the spindle.

Most often, for the production of a home-made drilling machine, do-it-yourself standard drawings are used, in which the electric motor is replaced with an electric drill. This allows you to reduce the complexity of the work. However, such designs are designed only for small loads.

Front independent production mini-machine should determine the type of work performed on wood and metal. This will depend on the characteristics of the equipment.

Homemade drilling machine from a drill

The most popular model currently is a mini drill machine. To make it at home, you only need to make a bed and a rack.

In some cases, it can be done without the use of homemade elements. To do this, you need a factory bed and a drill. It is not necessary to draw up drawings for this, however, such a design has one significant drawback - a large backlash. During the execution of work, the cutting tool is shifted relative to the drilling site. This must be considered before making a drilling machine.

It is best to use standard drawings for the production of a homemade drilling machine with your own hands. The production technology directly depends on the selected components. But experts recommend adhering to the following rules when choosing source material, as well as its processing:

• for smooth raising and lowering, you can use the steering rack. An alternative option is to adapt a mechanical jack;
• the supporting table and the stand are made of steel channels and corners. It is important to ensure sufficient mass of the lower part of the structure for maximum stability of the machine during its operation;
• separate control unit. Turning the drill on and off will be inconvenient. Therefore, it is recommended to install a standard switch on the side of the mini drill press.

During the execution of work, it is necessary to ensure the maximum accuracy of pairing of structural elements. The angle between the support post and the table should be 90 degrees. For filler models, the minimum thickness of the metal base plate must be at least 3 mm.

To increase the functionality of the equipment, you can do. It provides the ability to move the workpiece relative to the cutting tool. This will achieve maximum processing accuracy.

Homemade high power machine

If the desktop drilling mini-machine will have unsatisfactory parameters, you can consider other drawings of a similar design. Their difference from the above model is the use of an electric motor as the main power plant.

Making such a design at home will be problematic, as it will take a lot of time and effort. The electric motor can be made from a washing machine. The cartridge for attaching the cutting tool is not made by hand, it is taken from an old machine. Additionally, pulleys will be required to transmit torque.

In general, the technology remains the same. It is important to correctly calculate the optimal power of the electric motor, as well as provide for the possibility of changing the number of its revolutions. To do this, you can put a reducer.

As additional equipment, you can make a vise at home. They will fix the parts to perform precise processing.
