Do-it-yourself homemade drilling machines. Homemade drilling machine, design options, choice of materials, drawings Homemade desktop drilling machines

Everyone who uses a hand drill knows how difficult it is to keep a strict vertical with your hands. When drilling workpieces of large thickness, there is a risk of breaking the drill. Every time there is a desire to guide the tool along the guide, but there is no such possibility.

The second common task is to drill many holes of the same type in one workpiece. Holding a drill in your hands, doing such work is long and inconvenient.
Since ancient times, locksmith workshops have used drilling machines of various capacities. But their cost for home purchase is too high.

In addition, the home master does not perform drilling on an industrial scale. Therefore, such a purchase will never pay off.

There are factory-made vertical drilling fixtures that can turn a hand drill into a full-fledged drilling machine. Many of them are equipped with coordinate plates and movable vise.

Stand vertical for drilling holes with a drill

This is a really convenient purchase, but the cost of such a machine is comparable to the cost of a drill. Therefore, home craftsmen often make a homemade drilling machine.

The main advantages of the design– low cost and the ability to create a device that is perfectly compatible with your hand drill. If there is an unnecessary photographic enlarger, microscope or other mechanism with a vertical feed of the working unit in the house (barn, garage), the task is simplified.

It remains only to adapt the drill to the product. If there is no such bonus, the stand is made from scratch.

How to make a machine out of a drill using improvised materials

What should the guide stand for a hand drill consist of?

stable bed

Preferably with the possibility of installing a vice or other device that holds the workpiece. At home, it is made of thick chipboard, plywood, or textolite. In the center of the axis of the drill being installed, it is necessary to leave a hole with a diameter of a couple of centimeters.

Description of the necessary parts of a drilling machine from a drill

Guide upright

Here the imagination of developers is unlimited. It can be a bar, plywood plate, metallic profile or pipe.

The main principle in the manufacture is a strict vertical in relation to the supporting frame. Otherwise, the drill will deviate from rectilinear motion, spoil the workpiece and break.

In a wide range of plumbing work, drilling is perhaps the simplest and most accessible operation for everyone. As a rule, in production, drilling work is carried out using various drilling machines.

Depending on the tasks performed, these can be the most common single-spindle units, and multifunctional multi-spindle machines with numerical control.

Homemade desktop drilling machines

However, we will not be distracted by the description of all kinds of industrial drilling installations, especially since home master, for whom this article is intended, will hardly be interested in the subtleties of the design of a universal vertical drilling and boring machine. But the design of the simplest home-made drilling machine, which can be assembled from improvised material at home, will interest any "handy" master.

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

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

Of course, today in any specialized store many models of various machines are sold, including drilling machines, designed for use in home workshops. However, their cost is considerable, and not everyone can afford such a purchase, especially since with certain skills and desire, the simplest drilling machine can be made independently.

The most common types of homemade drilling machines are:

• Drilling machines based on an electric drill
• Drilling machines based on an asynchronous motor from household electrical appliances

Consider in in general terms manufacturing technology of each of these machines.

Drilling machine based on an electric drill

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

The weight of the electric drill is small, so for the manufacture vertical rack no particularly durable materials are required, it can even be made from boards or chipboard.

The design of the drilling machine consists of 4 main elements:

1. Base (bed)
2. Vertical stand or beam
3. Feed mechanism
4. Electric drill

The choice of the base of the machine, the frame, should be taken very seriously. The more massive it is, the less vibration will be felt during operation. If your farm has an old photographic enlarger for developing pictures, it can be adapted after a little refinement as a base with a stand. In the event that you didn’t find anything that could be adapted as a bed with a stand, this element can be made from a furniture plate with a thickness of at least 20 mm.

When attaching the rack to the frame, it is extremely important to get a right angle, since the accuracy and quality of drilling will depend on this. With the help of screws, two guides, cut out of metal strips, should be fixed to the rack, along which the block moves up and down, to which the drill is attached. The block should be made in such a way that the drill can be tightly clamped with metal clamps.

To reduce vibration, between the body of the electric drill and the shoe, you can install rubber gasket. The vertical movement of the block with a drill is carried out using a lever. To ensure the convenience of work, the feed mechanism should be equipped with a sufficiently powerful spring, which could bring the block with the drill to its original position. One end of the spring will rest against the block, and the other against a fixed beam, which should be installed on the rack.

If the drill will not be used autonomously, for greater convenience, you can disassemble its switch and install the on-off button directly on the bed.

Drilling machines based on asynchronous motor

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

It should be said that the design of such a machine is much more complicated than the above-considered design using an electric drill. Among other things, the motor washing machine quite heavy, which creates increased vibration and requires the mandatory installation of a powerful rack.

To reduce vibration, place the engine as close to the rack as possible or choose a fairly heavy, powerful frame.

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

For the manufacture of the pulley structure, you will need:

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

The movable part of the mechanism can be made from a hexagon, a tube of the appropriate size, a clamping ring, bearings, a tube with a threaded female thread to which the cartridge will be attached. The hexagon is an element of the transmission mechanism on which the pulley is put on.

To ensure a reliable connection with the hexagon, deep cuts are made at the ends of the tube. A compression ring and bearings are driven into the tube. It is necessary to ensure that the structural elements are fastened to each other very tightly, otherwise, the structure will collapse from vibration.

To manufacture the adjustment system of the machine, you will need a pipe with cuts of the appropriate size and a gear, the teeth of which must freely penetrate into the cuts on the pipe. In order not to be mistaken with the places of the cuts on the pipe and their size, you should roll out the plasticine on the pipe and drive the gear along it. The length of the ladder pipe must correspond to the height to which it is necessary to raise the chuck with a drill. The axis with a hexagon is pressed into a pipe with slots.

The design described above is rather complicated in execution, and, let's not dissemble, not everyone will be able to make it. Therefore, the easiest way is when manufacturing a machine with asynchronous motor, pick up a powerful steel frame and assemble the machine by analogy with a unit with an electric drill. True, it will not be possible to completely avoid vibration, in any case, and count on getting holes especially exact size when using this unit is not necessary.

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

In addition, radio amateurs, who, as a rule, drill holes of extremely small diameter in printed circuit boards, are recommended to assemble these structures in miniature, replacing the electric drill with a microelectric motor. Together with a voltage regulator, a microelectric motor will allow you to get almost perfect holes. An example of the construction of such a machine can be seen below in the photo.

When performing carpentry and plumbing work, an appropriate tool is usually used, designed to perform specific tasks. However, there are situations when it is much more convenient and easier to use special machines. They allow you to optimize the process and save time in the same type of work. Therefore, questions about how to make a drilling machine from a drill very often arise among modern masters.

Necessity or luxury

First of all, it is worth saying that it is very convenient to use such a device when making holes in small horizontal planes. It almost completely eliminates the drill backlash, which necessarily occurs when handmade. Even a small drill from a drill significantly increases the accuracy of the hole made, while minimizing the error. Also, such equipment saves a lot of time and effort if frequent use or monotonous work is necessary.

Almost all enterprises that carry out locksmith work are equipped with such units. The fact is that studies conducted in the field of labor protection have shown an increase in productivity and quality improvement when using them. Some of them even purchase a magnetic sole drilling machine in order to optimize production on large planes without the use of expensive equipment.

Why drill?

Currently, there are many designs for creating such equipment at home. However, most experts recommend making a drilling machine from a drill. This is due to the fact that this tool already fully contains all the necessary components and assemblies, and they do not have to be purchased separately. In this case, the fixation on the structure is carried out so that it is easy to remove the drill for independent work. As a result, we do not lose a tool that can be used independently.

materials

In order to create a drilling machine from it is necessary to purchase the tool itself. It is selected in accordance with the parameters that the finished device will have to have. At the same time, experts advise paying attention to products that have their own small backlash. Otherwise, the expediency of using it for work is called into question. You may also need:

• Guides. They use systems used in furniture production, or metal strips.
• Bed. Most often, it is made from a metal plate or a wooden box, on which magnets or ballast are attached for weighting.
• Fasteners. When they make a drilling machine from a drill with their own hands, they immediately select couplings or clamps suitable for fixing a particular tool.
• wood or metal constructions- depending on what material is to be processed.
• The spring required to implement the reverse stroke.
• If a drilling machine is created, then the magnets themselves will be needed.

Tool

In this case, the selection of the tool used depends on the material for creating the frame. However, it is immediately worth noting that a corner for measuring the connection of elements at 90 degrees will be needed in any case. Even a mini-drilling machine requires great precision in its manufacture, since this will subsequently affect the quality of the holes made.

Drawing

First of all, you need to decide on the designs of the final product and the material for its manufacture. However, there is no need to come up with too complex technical solutions or expensive nodes. Type drawing drilling machine from a drill is quite simple. It involves the creation of a strong and stable frame, on which a vertical tripod with a movable carriage is mounted. Considering this, Special attention it is worth paying attention to the implementation of moving the drill in a vertical plane, although the use of ready-made guides greatly simplifies this process. If you use the stand of a microscope, photographic enlarger or press as a frame, then the drawing will be based on their base, and the entire manufacturing process is greatly simplified.

Bed and tripod

Even a mini drill press needs a stable base. It not only must hold the entire structure, but can be equipped with various elements for fixing tools or other devices. Thinking through the device of a drilling machine, it is worth listening to the advice of experts. Many craftsmen recommend creating these devices from wood. Therefore, for the bed use wooden frame in the form of a small box. It has seats for mounting vise or other structures. If the product is planned to be used on large surfaces, then the bed is made of a solid plate with a drill hole. So you can implement the principle of drilling through.

Almost any device of a drilling machine involves the installation of a vertical tripod at an angle of 90 degrees to the bed. Therefore, it is very important to use an accurate one in your work. You also need to securely fix the tripod using additional mounts in the form of corners.

If the work is supposed to be at a certain angle, then certain devices can be made in advance that will be mounted on the bed. Most often, in such cases, ready-made ball vices with an adjustable angle of inclination are used.

Creating a movement mechanism

When a homemade drilling machine is made from a drill, then this stage special attention needs to be paid. The fact is that the vertical stroke should be soft, without distortions, play or displacements. Considering this, professional craftsmen it is recommended to use ready-made guides in the work, which can be taken from other devices. You can also use systems made for pulling out drawers for cabinet furniture. They are quite reliable and can withstand heavy loads.

Installation of guides is carried out directly on a tripod or special strips attached to it. In this work, it is important to use measuring tool, since these elements must also be placed at an angle of 90 degrees with respect to the frame and parallel to each other. Even small distortions or displacements should not be allowed.

The second part of the guides is fixed on a special carriage, where the drill itself will be installed. It is made of wood and adjusted to the dimensions of the original tool. Also, a small handle is attached to the carriage, with which the operator will control the movement process.

To implement the return movement and facilitate the control of the carriage stroke, a spring is installed on the machine. One of its ends is fixed at the top of the tripod, and the other is mounted on a movable mechanism. At the same time, the level of its tension is immediately checked, which, if necessary, can be changed by cutting the turns or stretching them. However, this setting is best done under load, which means that it is performed only after fixing on the drill carriage. Some masters recommend making the spring removable, it could be removed after work. So it will not stretch and weaken.

Drill fixation

Usually instructions telling how to make a drilling machine from a drill recommend creating special fastening systems, which in the end are very difficult to work with. However, if the tool is chosen correctly, then it can be fixed using conventional plumbing clamps used when creating a hose-to-pipe connection. In this case, it will be necessary to make certain changes to the shape of the carriage or even slightly correct the body of the drill.

It is very important that the tool is held tightly and moves in the clamp. Therefore, even at the stage of manufacturing the carriage, they practically do not leave free space for it, restricting it structurally from all sides. In fact, the carriage itself is a kind of bed for a drill, in which it will sit very tightly. Additional elements are needed only for the reliability of fixation. This approach greatly simplifies the design and allows you to quickly remove the tool if necessary.

Output

Considering the material presented above, we can conclude that a drilling machine from a drill can be made independently and without large financial costs. At the same time, the final product will be maximally adapted to the performance of specific technical tasks and will be able to satisfy the relevant requests of the end user. However, it is worth considering the fact that factory designs usually have a smaller error and are able to perform accurate work with a minimum tolerance. Therefore, such devices are usually suitable for private use or in small workshops where high precision holes are not required.

Those who have ever used an electric drill have encountered difficulties when it is necessary to make a bunch of holes. Paul troubles if there are holes in the board, but to make holes in the metal? To do this, the industry came up with a drilling machine. Those who have it are very lucky, and those who do not have it, prepare their pocket.

My pocket, personally, is small, so I can’t afford a factory drilling machine. Well, Chinese, made of tin, of course I can afford it, but it's bullshit. Soviet, semi-complete, are unreasonably expensive. I didn’t consider store racks for drills in principle, they were painfully “childish”. Wandering around the Internet I found a lot of homemade products, but the presence of turning works stopped me. You can order a couple of parts from a turner, but no one wants to share normal drawings, and when you design a part, a joint will always come out. A jamb came out - run back to the turner and ask to fix it. But one day I came across interesting video from Zhelezjaka about homemade rack for drill. Simple design, repeatable and versatile. While watching the video Zhelezjaka there were no analogues of this design yet.

I was going to make this rack for a year, and maybe more. After I went on vacation, I finally got to work. He made his own adjustments to the design, they do not fundamentally change the machine, but unify the materials and reduce the manufacturing time of some elements. I tried to use the minimum amount of purchased material, I tried to use the garbage that I had. But still not without shopping. From the main one, I bought a pipe for the guide, a corner and a strip, each position 1 meter.

Now we look at the manufacturing process. Actually, the guide for the carriage is also made of a square pipe 40x40x3 mm. I bought iron in a small hardware store, metal-roll is stored there almost under open sky and not particularly good quality. But this has one advantage, there you can feel everything and choose better. And so it happened. From the beginning I wanted to take a pipe with a wall thickness of 2 mm, but the seller and I could not choose an even piece. I took it with a wall thickness of 3 mm, thick-walled pipes are much smoother. Steel is steel and traces of corrosion are an integral part of it. Therefore, I had to clean almost the entire rental, especially the guide. I did not bring it to the state of cat's pride.

I forgot to say that in advance I prepared a set of preliminary drawings, according to which I made the basic elements. A set of final drawings will be posted at the end of the article. Workpiece mode in size. Here is the first deviation from the author's project, I took the corner for the carriage and bracket 45x45x4 mm. A 40x40 pipe fits perfectly into it, you don’t need to cut anything and an excellent mounting gap is formed (seen in the photo below). I tried to repeat the author's manufacturing technology.

I put sandpaper, pressed it with clamps on the guide, brewed everything from the heart. And then remove the figurines, clamps so that "mom do not cry"! I was able to remove the rack bracket only by knocking it on the rest of the 45th corner. Next, I cut the entire corner, welded the carriage, put twice as much sandpaper and that's it .... How much was spent swear words, smoked cigarettes and cursed everything that was moving nearby, you can no longer remember, but it was not possible to separate one from the other. How the author is so simple, I do not know. And the technology, in my opinion, should be as follows: we put it in a double-folded sandpaper -> we crimp it with clamps -> we grab the edges at all four corners by welding -> we completely weld one of the edges -> let it cool completely -> try to remove it from the mandrel. If it came off the frame, then boil the second edge. If it doesn’t work, then we cut off the tacks on the unwelded edge and gently remove the guide. In the photo below are already welded blanks, the smallest will not be used.

The bed was made from what was. And I had almost a meter of channel 8. I adjusted the length of the bed to the length of the remainder of the square pipe, which remained after the manufacture of the guide. Below is a picture of the rack bracket installation process. To be honest, this design of the bed is not very good. The shelves of the channel are all crooked, one piece has a concavity, the other has a convexity. Horror, not rental. He pretended to put it at a right angle, though it is not clear to which plane. I will deal with perpendicularity later.

and back. There are two threaded holes in the back panel. These holes will serve to fix the machine in a horizontal position when processing wood.

And fasteners for fixing the rack in a vertical position. A lone bolt is welded for grounding. Holes for the wires are not visible here, but they are in the drawings.

About adjustable feet. By some chance, there were no standard legs from a refrigerator or washing machine, I’m just amazed. I had to make a bolt and an enlarged washer, the price of the issue was a couple of kopecks. But I had those things in which the legs are twisted, but high nuts are perfect in their place.

Drum, the one that will scroll the cable. I approached the manufacture of this part creatively. It works exactly the same, but is done differently. steel bars with a diameter of more than 10 mm in a home barn is difficult to find and my barn is no exception. Plus immediately solved the issue of a removable handle. As an axis, I used an M10 bolt with a short GOST thread. Having cut off the excess from it, I got a smooth axis. The bolt head will serve as a kind of engagement element for the axle with the handle. The outer part of the drum will serve water pipe. If you don’t have such a pipe in your metal garbage, then you can replace it with a drive bought at the nearest plumbing store. To center the axle, I had to make bushings, so to speak, manual method, without lathe. To do this, I clamped two M10 nuts on the remaining trim of the bolt (do not throw away the trim, it will come in handy later), inserted it into a drill and turned the entire structure on an electric grinder. Since there is no longer a thread on the trim of the bolt, the thread in the bushings must also be drilled out. A hole with an M5 thread is made in the bolt head for attaching the handle. It turned out pretty good.

In the picture below, I have already welded the bushings to the axle, the main thing is not to forget to put on one of the eyes first. Holes are made in the outer cage of the drum through which the cage will be welded to the bushings. All dimensions and clearances are shown in the drawings.

Here is the result:

Carriage. There is nothing special to tell here, we collect everything according to the drawings. Only one addition. In the original, the carriage is stopped by one of the adjusting bolts. After all, they are adjusting, so as not to touch them, so after welding all the parts, I made an additional threaded hole specifically for the locking bolt. I made the thread for the adjusting bolts only with a rough tap to get rid of spontaneous unwinding.

View from the other side. Excuse my welds, as I can, I cook.

The handle is the lever. After looking at the photo, do not throw tomatoes. In my performance, the lever is made of rozhkovo- ring spanner at 17. He had a bursting cape, so I gave a second life to an incomplete key.

On the one hand, I welded a homemade washer from a strip onto the cap part of the key.

Next, an element that is not in original design- this is emphasis. This stop is attached to the top of the guide post and is used when fixing the machine in a horizontal position. The pole mounting holes are not aligned to minimize rotation of the stop.

Another new detail. I named it "table". Since the plane of my bed is missing, I had to dodge. It is made from a piece of laminated chipboard, not the best way, but so far. With the help of screws, I have the opportunity to set the work plane perpendicular to the rack.

This is how it looks. The photo also showed an auxiliary carriage, on which a ruler and a woodworking tool will be placed.

And here you can see the element of the table adjustment.

It's time to make a bracket for mounting the drill. And again, the materials that I had were used. Clamp from a strip of 25x4 mm, removal from the pipe 30x30x2. This strip fits perfectly inside the pipe, which makes it easy to attach one to the other. And this turn of the clamp ensures perfect alignment. The clamp is made by tapping a strip around a pipe with a diameter of 40 - 42 mm.

A little closer.

And carefully brew. I was worried about the quality of these seams, since this place is the weakest in the whole construction.

Let's put aside the welder for a while and get down to the drill. As I said, I was going to make a machine for a whole year. During this time, he got a drill, which is not a pity. They gave it to me as it was not working. Inside, the wire was simply transferred and over time it burned out in this place. The wire was corrected, but the drill, as you can see, is very tired and full of backlash. First of all, the cartridge and rolling bearings went under the replacement. The shank bushing was also broken.

To be honest, I would have torn off the hands of these designers, who added a ratchet function to a simple drill. Zero sense, the bearings are broken and the axial stroke of the cartridge adds to all the delights. The most interesting thing, at least in this drill, is that the ratchet assembly is the same size as the outer race of bearing No. 608. My attempts to knock the ratchet out of the silumin clip failed, I had to cut off the teeth with a hacksaw and go to the market to look for a bronze bushing. And on the market for this sleeve they broke an absurd price, which I was very offended by and basically left with nothing. In place of the bronze gold bushing, the inner race from the same 608 bearing fits perfectly in size. One bad thing - this replacement is one-time, in next time you will have to change the sleeve along with the chuck shaft. Let's see how long it lives. To eliminate the axial movement of the shaft, instead of a repulsive spring, I installed a bushing made of a sanitary fitting, and on the other side I placed a turned washer. The bearings have been replaced, the backlash has been eliminated, the mechanisms have been lubricated.

Attention, the faint of heart, please do not look at the following picture! Since this drill was specially reserved for the machine, I tried to make it so that it could only work in this machine. I cut off the handle. From the barbarian ... The start button was removed, the reverse lever remained in its native place, the cut was covered with a neat cap.

And what did I end up with. I placed the button in the cavity of the bed, made a threaded hole in the front panel and screwed the adjusting screw there. Thus, I received a remote speed control unit. You tighten the screw, it gradually presses the button that changes the speed of the drill. Separately, I mounted a toggle switch for turning on the machine.

Below is the process of assembling the spindle bracket. I fixed the guide from the printer into the cartridge, which made it possible to relatively accurately set the axis of the tool perpendicular to the table.

Here is the welded bracket. Immediately made a hole in the table and bed. In the bed, I cut a thread for screwing in the center to hold the wooden workpiece during turning. Then he began to procure parts for the manufacture of a hand-cuff (Hand-cutter - a stand for cutting tool on a lathe).

And here he is, ready. It turned out to be a simplified functionality, there is no height adjustment. I have never worked on a wood lathe in my life, and on metal, too, I will learn and try.

And in principle the machine is ready, for the test it was chosen practically maximum load. The first serious hole was made with a 13 mm drill in the front panel of the machine for installing a toggle switch, let me remind you that the panel is made of a 4 mm thick strip. The result exceeded all expectations, without pre-drilling and with a minimum of effort, without even straining, I drilled a hole in a matter of seconds. I rejoiced, the state of euphoria passed and noble traces of young rust began to rush into my eyes. I was in a hurry to collect everything and did not bother to paint it in detail. Now I have to take it all apart.

As always, I waited for a cold snap to start painting. Therefore, I had to paint in the barn, not a pleasant pleasure, paint on the street. I chose green color, this association since childhood - if the machine, then green.

Bed painting. Too lazy to take out the wire, the collective farm is the collective farm.

The paint has dried and here is the result of the work:

On the other hand:

And in lathe position:

Here are the promised drawings. I ask all normocontrollers and very smart ones not to comment on the drawings, and not even to look :)) it's a joke. Use on health! I even made a specification by which you can estimate the volume necessary materials. But I must warn you, do not blindly believe the drawings, double-check, I'm not a robot and I can sometimes make mistakes.

The result is a great tool. I can’t fully appreciate the turning version yet, since I only have a chisel instead of incisors. But as a drill there is a couple of "buts":

1. Try to make the bed like the author Zhelezjaka, the design will be simpler, lighter and smoother.
2. One shoulder handle is terribly uncomfortable, it is difficult to explain what the inconvenience is, but uncomfortable. I will remake in three shoulder. In my version, it's simple, unscrewed one and screwed the other. If you do it according to the original version, then pay attention to this.
3. The handle is taken out, as it were, behind the machine, which increases the required free space. In the future, I will carry it closer to the spindle by means of a chain drive.
4. The front center (the jagged thing that rotates the wood stock) doesn't hold the wood very well. The structure needs to be changed.

And do not forget to use the tools when working personal protection. Do not violate safety regulations, no matter how stupid and ridiculous they may seem.

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, a mini CNC drilling machine allows a person to engage in such work that he can independently complete, if he can, then with the use of a huge amount 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 making a drilling machine with your own hands is not difficult at all.

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.

1 Features and purpose

Drilling machines 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.

In addition, it should be understood that filigree precision will be required of you, because this detail is just a 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. If you use a mini machine in your work, then the work time is reduced several times. It already has all the essential tool. 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.

1.1 Parts 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 drilling machines are made or how to make a drilling machine with your own hands, then first of all you need to figure out the details that will be used when assembling it.

Fortunately, a DIY mini bench drill consists of a few basic parts. The device of the drilling machine determines the quality of the device itself, but here it all depends on many factors.

So, drilling machines consist of:

• beds or bases;
• fixing rail or frame;
• device position control mechanism;
• attachments for the working mechanism;
• engine 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 doesn't really matter if you're looking at a benchtop mini PCB drill or a standard benchtop.

You, of course, you can use different parts for assembly homemade drilling machine, however general scheme and the device of the drilling machine will remain the same. The difference will be only in specific details and their dimensions.

For example, a home-made desktop unit for drilling mini-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 for drilling boards.

Also when developing mini boards you will need a much simpler and smaller engine, as drilling mini boards requires more fine work where power is not a priority.

1.2 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. For such purposes, it is necessary to use a table with good supports, special stands, you can mount from a photographic enlarger, etc. Even a cabinet of the right size and dimensions will do, but it's up to you to decide.

If we are considering a desktop sample, then the coordinate table here will act as the first base on which the desktop drilling machine itself is already installed. In this case, the bed can be made from 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 parts can be used for manufacturing.

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 a 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.

An asynchronous engine from washing machine or something similar. You can use the engine from the drill or the drill itself.

2 Scheme of creating a machine

If we consider only the simplest models of equipment, which you can quickly assemble with your own hands. That is best suited for these purposes standard scheme assembly of drilling equipment.

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 one is quite difficult option, and it consists in assembling the machine from a separate engine, collets, guides, etc.

Stages of work:

1. We collect the table and the base for the mini 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, in order to prepare the second option more time, effort and energy will have to be spent. Yes, and certain engineering skills will not be superfluous either.
