Good day! There are a lot of people on this resource who are engaged in electronics and independently prepare other payments. І skin from them I will say that the drilling of other boards was made. Dribni open to be drilled with hundreds of leathers and independently solve your own problem.
At this article, I want to give your opinion on the project of a drilling verst, which skin you can choose yourself and you don’t need for that CD-drive or an object table for a microscope.
Design description
In the basis of the design, to finish a hard-wired 12-volt engine from China. In a set with a stench engine, they sell a cartridge, a key and a dozen drills of various diameters. Most of the radioamators simply buy the engines and drill the money and the instrument is in their hands.
For the linear movement of the engine, I made the polishing of the shafts with a diameter of 8mm and the linear bearings. Tse gives the possibility of minimizing backlash in the next field. You can know the numbers from old printers and buy them. Linear bearings are also wider and more accessible;
The main frame is crushed from 5mm plywood. I chose plywood, because it’s cheaper for someone else. Like the material, so the very design. From the other side, you don’t care about anything (however, it’s possible) just look at your own details from steel or orgskla. Other details folding form 3D-printed.
To lift the engine at the exit, the position of the vikoristano was taken by two zvichayny clerical gums. At the upper position, the motor itself is switched on for additional micropermeability.
W salutary side I handed over a place to take the key and a small pencil case for drills. Grooves in a new muddy clay, to work with a handy guard, drilled from a different diameter.
Ale, everything is simpler than once to play on the video:
On the new one, there is little inaccuracy. At that time, I got a defective engine. Really, at 12V, the stench is on an unfriendly course of 0.2-0.3A, and not two, like moving at the video.
Details to choose
- Dvigun with a cartridge and collet. From one side, the cam chuck is even more handy, but from the other side it is richly massive for the collet grip, so it is often slender to the battle and even more often it is brought to dodatkovo balance.
- Plywood details Entitlement for files for laser cutting in dwg format (prepared to NanoCAD) can be charged in the final article. Dosit just know the company, how to deal with laser sharp materials and transfer the file to them. I will designate those that the comrade of the fanery can change differently. Leaves are trapping like trohi thinner for 5 mm, so I robbed 4.8 mm.
- Overwrought parts on a 3D printer. Sending files for other details in stl-format can also be found in the end of the article

Storage
The whole process of reporting testimony on video:If you follow the same sequence of actions, then it will be easier to choose the layout.
The axis looks like this The latest set of all components for folding
For picking them, you need the simplest hand tool. Screwdrivers, hex keys, pliers, wire cutters, etc.
Before that, start picking up the yards and work out the overruling of the details. You can see that you can pour, pidtrimki, and also open all the doors with a drill of a large diameter. Plywood details along the line of the rose can be garbled. You can also work it with an emery paper.
In addition, as all the details are ready, it is easier to install linear bearings. The stench creeps into the middle of the overworked parts and is screwed up to the side walls:
Now you can choose a plywood base. The side walls are installed on the base, and then the vertical wall is inserted. At the upper part there is an additional detail, which sets the width at the upper part. When twisting the screws around the plywood, do not apply a great susil.
At the table in the front opening, it is necessary to drill a countersink, so that the screw is hidden behind the head without worrying about drilling the board. From the end there is also an overstretched fastening detail.
Now you can proceed to the selection of the engine block. The wine is squeezed by two details, that chotirma with screws to a crumbly foundation. When installing yoga, it is necessary to keep the vents so that the ventilation openings are filled with water. On the basis of the wines, fasten with additional clamps. On the back, the shaft will seep into the bearing, and then the clamps will flicker on the new one. Also, install a M3x35 screw, which is a micropermeable for the future onslaught.
The micro-permeator is installed on the openings with a button at the back of the engine. You can recalibrate the new yoga camp.
The gums are thrown on the lower part of the dvigun and stretch to the horns. The tightness needs to be adjusted so that the engine rises to the end.
Now you can solder all the darts. On the block of the dviguna, that charge from the micro-permeable є open for clamps, to close the wire. Also, this inspection can be carried out in the middle of the verst and on the return side. Be sure to solder the wires on the micro-permitters to normally closed contacts.
It was only left to put a pencil case for the drill. It is necessary to squeeze the top cover tightly, and tighten the bottom cover slightly, using a vicorist nut with a nylon insert.
On whom the warehouse is finished!
Additional
Other people, who already chose such a layout for themselves, made a lot of propositions. I, if you please, will revise the main ones, stripping them of the author's look:- To the point, Tim, who has never worked with such details before, it’s good to guess that plastic like 3D printers is afraid of heating. Therefore, be careful here - do not go through the varto open in such details with a high-speed drill or a Dremel. Handles, handles.
- I would also recommend installing a micro-perm switch on your own early stage choosing, so how to bring yoga to the already pіzbiranoї bed needs more zoom - even a little free space. It wouldn’t hurt to please the minds in advance if you want to fix the contacts of the micro-permeability (and even more quickly - solder the darts to them and protect the place of soldering with the heat-shrink tubes), so that when soldering, don’t damage the plywood parts to the mold.
- I might have been spared and the cartridge on the shaft was not centered, which led to a serious vibration and hum of the stat. It was far away to correct the centering with “pliers”, but not good option. So it’s like bending the whole rotor, and taking a cartridge is no longer realistic, it’s a fight that I’ll pull myself up all over.
- The tightening of screws with lock washers should be carried out in this order. Tighten the screw until the moment when the puck closes. After that, turn the screw 90 degrees and it will snap.
- It’s good for someone to get up to a new speed controller according to Savov’s scheme. Turn the engine properly, if there is no pressure, and move the wrap when pressure appears.
Drilling work for other boards is included in the category of minimum-possession of special recognition. For a job, such a machine can be built with your own hands, vicoristing for which accessories are available. Be-yaky fahіvets to confirm that it is important to manage without vikoristanny similar to the device at vyrobnitstvі elektrotehnіchnіchіch vіrobіv, elements of circuits of such are mounted on special other boards.
General information about drilling typesetting
Whether any drilling verst is necessary in order to ensure the possibility of efficient and accurate processing of parts made from different materials. There, where a high accuracy of work is required (but it should be carried out before the drilling process is opened), it is necessary to switch off manual work as much as possible from the technological process. Podіbnі zavdannya i vіrіshuє be-yaky, including self-confident. It is practically impossible to do without a versatility when processing hard materials, for drilling, having opened at some zusil of the operator himself, you can use it.
Construction of a floor-mounted sverdluvalny verst with a belt drive (press to increase)
Be it a workbench for drilling - the same construction, selected from the impersonal warehouse parts, as if it were supposed to be fixed one at a time on a supporting element. A part of tsikh vuzlіv is fixed on a load-bearing structure zhorstko, deyakі can move and fix in one or more spacious positions.
The basic functions of any sverdluvalny verstat, for the rahunka of which and the processing process is ensured, є the wrapping of that movement at the vertical straight line of the cutting tool is the sverdl. On rich current models of such workbenches, a working head with a cutting tool can also move in a horizontal plane, which allows you to wiggle for drilling as many openings without changing details. In addition, in modern typesetting for drilling, automation systems are actively promoted, which significantly increase productivity and increase the accuracy of processing.
Below, for the butt, there is a list of design options for the boards. The skin of these schemes may be suitable for your layout.

Let's take a look at the fact that all these universities are now recognized and how to choose a self-contained mini-verstat from them.
Structural elements of the drilling mini-versat
Drilling mini-layouts, assembled with their own hands, can be seriously refurbished one way: everything is deposited, in addition, as composing materials were used for their own preparation. However, both factory and self-contained models of such possession are based on the same principle and are recognized for the implementation of similar functions.
The supporting element of the structure is the bed-base, as it also ensures the stability of the drilling process. Vykhodyachi z recognition of this constructive element, to prepare the frame of the bazhano from the metal frame, it is possible to significantly change the totality of the solution of all the knots. As if to fight with your help, you will not be able to secure the stability of your self-reliant workflow, which means that you will not achieve the necessary accuracy of drilling.
The role of the element, on which the drill head is attached, the transitional frame is fixed, which stabilizes. It is best to prepare from a metal lath or cuts.
The bar and shock-absorbing attachment are designed to ensure the vertical movement of the drill head and its springiness. How such a bar (її more quickly fixed with a shock absorber) can be beaten to a design (important only, so that the work was put on it). In this case, a tight hydraulic shock absorber may be in good time. If you don’t have such a shock absorber, you can make the bar with your own hands, or you can beat the spring structures, taken from old office furniture.
The control of the vertical movement of the drilling head is carried out behind the help of a special handle, one end of which is connected with the body of the drilled mini-verst, with a shock absorber or a frame that stabilizes.
Fasteners for the engine are mounted on a frame that stabilizes. The construction of such an attachment, like a wooden bar, a collar and a collar, will be based on the configuration and design features of other nodes of the sverdluvalny verst for other boards. The choice of such a fastening is not only necessary for the yogo superficial fixation, but also that it is your responsibility to put the shaft of the electric motor on the stand in the direction of the displacement bar.
The choice of an electric motor, which can be used to equip a mini-drilling machine, which is assembled by one's own hands, is not guilty of everyday problems. As a drive unit, you can use an electric motor like a compact drill, a cassette recorder, a computer drive, a printer, and other attachments, which you don’t already have.
Depending on what kind of electric motor you know, the locking mechanisms of fixing the drill bits are selected. The most handy and versatile of these mechanisms are chucks like a compact drill. If you don’t know how much cartridge you need, you can beat and collet mechanism. Choose the parameters of the clamp attachment in such a way that it is possible for him to fix even more drill bits (or to make drill bits expand "micro"). For the installation of a clamping attachment with an electric motor shaft, it is necessary to use adapters, the design of which will be determined by the type of the selected electric motor.
In addition, some kind of electric motor was installed on your drilling mini-vest, it is necessary to choose a living block. With such a choice, pay attention to those that the characteristics of the living block corresponded to the parameters of the voltage and the force of the stream, to the extent that the electric motor is protected.

The procedure for choosing a self-contained annex
As practice shows, it is easier to create a self-made layout for drilling openings in other boards than in a singing sequence. Children are required to be offensive to the algorithm.
- The installation of the bed is fixed and the legs are fastened to the lower side, as if the stench is transferred to the structure.
- To the selected bed, a bar is attached to the trim frame, on which the drilling head will be mounted.
- The trim frame is mounted with a shock absorber, which is also fixed on the frame.
- A handle is installed to guide the displacement of the drilling head, which goes behind the shock absorber or the frame of the trimmer.
- An electric motor is mounted, the position of which is regulated by a relay.
- A collet or a universal chuck from a drill is attached to the drive motor shaft for additional adapters.
- The installation of the living block is to be completed, which goes behind the electric motor for additional electric darts.
- A drill is installed at the cartridge and it is superficially fixed at the new one.
- Zibraniy self-confident layout test, trying to drill for yoga to help open a sheet dielectric.
In order to make your self-contained drilling mini-versat, it is possible to zavzhdi rozіbrati i doopratsyuvati, for zadnannya yogo constructive elements in the best vikoristovuvat bolts and nuts.
- Do you want to look around the mova pide about the preparation of a miniature drilling versat in home minds from handicrafts. The article is recognized as important for radio amateurs, who often have to independently prepare other payments. But such a more compact possession, like the representations below the verst, will be korisim not only in the field of electronics, but also in other government rights.
The basis for the design was the details of the CD ROM, which is in harmony, of the computer. More precisely, it will be necessary to have a metal frame installed on the її flat with a pair of straight ones and a carriage, whose fragment of the testimony is in the photo below. Meta zvuchayno I have chosen a drill bit from handy materials. Because of what was in the state and could become in good fortune with such a possession.
The engine will be mounted on the wrought carriage, and then it will be picked up by itself do-it-yourself drill maker. In order to close the yoga, a special trim was prepared in front of the bracket with a 2mm sheet steel slit.
Electric motor
At trimach, open the opening to the shaft of the electric motor and open the screw, yak trim the bracket from the motor. On the back for drilling, I will add a block of stasis to an electric motor DP25-1.6-3-27, which works in the form of a constant voltage of 27v and develops a tension of 1.6 watts. See photos:
In the process of testing this motor, it was installed that it does not have the necessary strain for drilling in sclotextolite. 1.6W is clearly not enough for that, a little more power and more power.
The photo shows do-it-yourself drilling machine with electric motor DP25-1.6-3-27
At the same time, that the power unit is not very productive, it happened in the event of a new movement and shukat the engine of a sudden tightness. Obviously, in response to the needs of the necessary dvigun, it’s a good hour, the process of preparing a troch of pins. Ale yak seem "light is not without good people and a friend gave me an electric motor from an old non-working printer.
New electric motor
I’m starting to move the engine again, I don’t have a nameplate with markings, I don’t know why. Ale tightness yogo wistachalo, schob pick up do-it-yourself drilling machine. A metal gear is pressed onto the armature shaft. The diameter of the shaft on the engine is 2.3 mm. Then I removed the gear from the shaft, and replaced it by putting a collet clamp and trying to drill the sprat by opening it with a 1.2 mm drill. The result was surprisingly less receptive, and the motor miraculously coped with the drilling of 3 mm textolite at a voltage of 12v.
Here it is shown how I creaked the engine from the triplet trim to the kovznoy carriage:
Support of the sverdluval outbuilding of the vikonan with a ten-millimeter screed of sclotextolite.
The following details are prepared for the foundation of the building:
To ensure stability, do-it-yourself drilling verst, in the lower part of the base there are built-in gum support feet:
Construction
I will add a metal structure to the console image, so that we can carry the chassis and install it on the new electric motor for the help of two special trims. The frame with the motor is installed on a small stand in the lower part of the verst. Such a variant of the system, having allowed the completion of the great drilling of the textolite beyond the scope. Eskiz I will add it below:
Below is a picture of a finished drilling versta
At the working part I will add on the photo you can see the installations for lighting the light:
In the image shown, one can see a too great step in the lightness of light. In fact, everything seems to be correct:
The design of the vikonan at the look of the console gives the opportunity to work open at the workpieces that are large in width, larger than 140 mm, and that splendidly large dozhini.
Vimiryuvannya core area for drilling:
As shown in the image, the bottom of the area in front of the front part of the ruhomoy carriage of the verst to the center of the drill should be 69 mm. Therefore, the width of textolite blanks for other boards can be approximately 135 mm.
Ruhomy mechanism
For lowering that drilling mechanism, a special importance of the onslaught was transferred:
To fix the drilling knot over the workpiece in front of the drilling cob, then turn it back, so that the reverse is secured by the turning spring. It is placed on a direct axle:
This image shows the scheme for adjusting the revolutions of the electric motor in automatic mode, so as to lie down in the rotation stage.
Newsletters at:We have already learned to work hard, now you need to drill open. You can use a manual drill, you can use an electric drill, you can use a bench drill ... It’s not easy to use an electric drill - the drills break often. The machine is good, but it's too expensive. That boulo was praised for the decision to bungle himself.
Stanina. For a long time shukav іz what to build the bed. In the vastness of the Internet, I know the idea of how to stand victorious to make a tripod like a microscope. To the right behind the malim - to know the half-man's microscope. It turned out to be more convenient ... Ale, after three trips, I knew a tripod in the form of a microscope (without a thin tube) for $ 20.
Dvigun. I had a chance to think no less than the bed - ready to move with a cartridge for $ 40 ... Get a screwdriver - it's too expensive, that Skoda. And the axis of the motor for a 12-volt screwdriver is yakraz! The cost is $9 and the delivery is simple - to the market, where the power tool is repaired.
Cartridge. On the radio, there are collet cartridges (pictured below), but having tried 2 pieces of intelligence - bullshit. The battle was stronger than it was, you won’t fall asleep. Know the miracle cartridge of the company dremel 4486, the axis is:
but before the new one you need to have an additional adapter, that cost is fine - about $ 20. For the time being, I’ve been zapping on a collet cartridge, but I’m whispering to you to replace it.
Patron (2 series).
I grew up on a dremeliv cartridge and bought yoga. Cost of wine 80 UAH (16 $). And up to the new turn the adapter. Chair axis:
The patron's design is even more cunning, but the knowledgeable people showed me the parameters. Diameter 7.05 mm 40 threads per inch. On the ready-made adapter, the shaft is wound up tightly, but without an annual susilla!
Photo of the finished design with a cartridge:
The adapter is mounted on the shaft to finish it strongly, so it was necessary for it to be reinforced with screws. Test drilling showed miraculous results! We don't know the battle!
Wrap Regulator. Yakbi having taken the screwdriver out of the regulator, then it would be possible to use yoga, but there was no regulator in me. So it happened to vigadati. It turned out that everything is easy to finish. Having taken the controller attiny13, on which implementation of the PWM, the voltage was applied to the output 3. Visnovok 2 serve to turn on the engine. On the new pedal, that vimikach is connected, on the vipadok, as if there were no pedals. Yak the key by freezing the irf540 transistor.
Fixed fee.
Firmware.
The firmware is available in two variants - with a smooth start and a strong start. who should be like and what a mover to stand. My dvigun, at a start-up, slowed down to 20A, which is a bit buggy.
fuses are included in the project, but if there is no codevisionavr, then I will repeat them here:
Zliva - rose of life and the regulator, right-handed - vimikach and rose of the pedal connection. At the bottom of the transistor (wicorist frame as a heat sink).
I didn’t use microfeed for my “microscope”, otherwise I didn’t need it, but half the turn of the feed handle (black handle) should be brought to move the drill by 15-20mm, which is sufficient for comfortable drilling.
Regulators for manual drilling of boards.
I buy radioamators. Don't chill your soldering iron. In principle, there are many different schemes of regulators on the Internet, choose to your liking, otherwise you won’t be tormented for a long time in jokes, and you won’t be able to propagate your respect for a few variants of schemes in one article. Please note that we won’t be able to describe the principle of a robotic skin circuit, you will be given the principle of a regulator circuit, as well as a board to it in the LAY6 format. So let's do it.
The first version of the impulse controller on the LM393AN microcircuit, powered by an integrated stabilizer 78L08, the operator is equipped with a polypropylene transistor, which is powered by a hand-held motor. Principle diagram:
Adjustment of wrappers is controlled by potentiometer R6.
The voltage of life is 18 volts.
The LAY6 board in the format before the circuit on the LM393 looks like this:
Photo view pay LAY6 format:
Rozmir pay 43x43 mm.
Raztashuvannya vysnovk_v field-effect transistor IRF3205 is shown on the stepping little:
Another option can be made wider. Yoga is based on the principle of pulse-width regulation. The circuit was inspired by the microcircuit timer NE555. Keruyuchі impulses from the generator go to the gate of the polovik. You can put transistors IRF510 ... 640 in the circuit. The voltage of life is 12 volts. Principle diagram:
The regulation of the motor wraps is controlled by a changeable resistor R2.
IRF510...640 is the same as the IRF3205, the picture is bigger.
The LAY6 board is designed to the format up to the NE555 circuit, looking like this:
Photo view pay LAY6 format:
Rozmir pay 20 x 50 mm.
The third version of the speed controller circuit can not lessen the popularity of the middle radioamators, lower SHIM, її dictatorial peculiarityє those that regulate the speed automatically and lie down on the shaft of the motor. Tobto, as the motor is spinning at unfriendly speed, the speed of its wrapping is minimal. When the tension on the shaft is increased (at the moment of drilling the opening), the wraps are automatically increased. In neti qiu, the scheme can be found on the “Savov Regulator” request. Schematic diagram of the automatic wrapper regulator:
After folding, it is necessary to install a small regulator, for which, at idling, the motor is equipped with a substroyuvalny resistor P1, so that the wrapping is minimal, but so, the shaft wraps without rivkiv. P2 serve for adjusting the sensitivity of the regulator to increase the tension on the shaft. With a 12-volt live power supply at 16 volts, 1N4007 can be replaced on similar ones up to 1 Ampere, a light diode, for example, AL307B, LM317, can be put on a small heat engine, another board is covered for the installation of a radiator. Resistor R6 - 2 watts. If the motor is wrapped in rows, increase the value of the C5 capacitor.
The circuit board of the automatic wrapping regulator is shown below:
Photo-view of the board of the automatic wrapping regulator LAY6 format:
Rozmir pay 28x78 mm.
All other boards are made on a one-sided foil-coated textile.
