For work on the house of functions, the drill is enough, but more accurate equipment may be needed to improve the quality and productivity of labor. One of the most popular varieties is a boring mini-machine made with their own hands.
Components of drilling machine
The first stage in front of the production is to study the design. This is recommended to take a drawing of a standard machine and get acquainted with its components. It is important to understand the general principle of operation and to further determine the optimal scheme of the homemade design.
The main functional purpose is to form the holes of various types. Depending on the configuration of the equipment, there may be drawings of vertically drilling, coordinate-boring, radial-drilling, additive models. The difference between them is the ability to change the direction of the cutting tool. For domestic needs, the vertically drilling mini-machine is most often made.
Structurally, it should consist of the following elements:
- stanna. The reference part on which the vertical stand is attached;
- rack. Designed to install electrical equipment;
- electrical components. They include an electric motor and a mechanism for transferring torque spindle.
Most often, standard drawings in which the electric motor is replaced with its own hands is used to produce a self-made drilling machine. This allows you to reduce the laboriousness of the work. However, such structures are designed only for small loads.
Before independent production, the mini-machine should determine the type of wood and metal work performed. This will depend on the characteristics of the equipment.
Homemade drilling machine
The most popular model is currently a boring mini-machine from a drill. For its manufacture at home, you will need to make only a bed and a rack.
In some cases, it can be done without the use of self-made elements. To do this, you will need a factory bed and drill. It is not necessary to draw up drawings for this, however, a similar design has one significant drawback - a big backlash. During the execution of work, the cutting tool is shifted relative to the drilling site. It must be taken into account before making a drilling machine.
It is best to apply standard drawings for the production of a homemade drilling machine with their own hands. The production technology directly depends on the selected components. But experts recommend adhere to the following rules when choosing the source material, as well as its processing:
- for smooth lifting and lowering, you can use steering rack. An alternative option is the adaptation of a mechanical jack;
- the reference table and the rack are made of steel channels and corners. It is important to ensure a sufficient mass of the lower part of the structure for the maximum stability of the machine during its operation;
- separate control unit. Turning on and off the drill will be uncomfortable. Therefore, it is recommended to install a standard switch to the side part of the mini-drill machine.
During the execution of work, maximum accuracy of conjugation of structural elements should be ensured. The angle between the support resistant and the table should be 90 degrees. For additive models, the minimum thickness of the metal support plate should be at least 3 mm.
To increase the functionality of the equipment can be made. It provides for the possibility of moving the workpiece relative to the cutting tool. This will achieve maximum processing accuracy.
Homemade High Power Machine
If you have unsatisfactory parameters - you can consider other drawings of this design. Their difference from the above described model is to use the electric motor as the main power plant.
Make a similar design at home will be problematic, as it takes a lot of time and effort. The electric motor can be made of washing machine. The cartridge for fastening the cutting tool is not done with their own hands, it takes it from the old machine. Additionally, pullees 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, and also provide for the possibility of changing the number of its revolutions. To do this, you can put a gearbox.
As an additional equipment, you can make vice at home. They will fix items to perform accurate processing.
The video material shows an accurate scheme and drawings for the production of a mini-drill machine with their own hands:
Examples of drawings and finished machines
Anyone who uses a manual drill know how difficult it is to keep a strict vertical hand. When drilling a large thickness billets, there is a risk of breaking the drill. Every time the desire arises to lead a tool on the guide, and there is no such possibility.
The second common task is to chop multiple holes in one billet. Holding a drill in his hands, make such a job for a long time and uncomfortable.
In the footmake workshops, ancient times used drilling different power. But their cost for home purchases is too large.
In addition, the homemade master does not perform drilling on an industrial scale. Consequently, such a purchase will never pay off.
There are factory devices for vertical drilling, capable of turning a manual drill into a full-fledged drilling machine. Many of them are equipped with coordinate plates and moving visits.
Rack vertical for drilling holes drill
This is really a convenient acquisition, but the cost of such a machine is comparable to the cost of a drill. Therefore, homemade masters often make a homemade drilling machine.
Main advantages of construction - low cost and the ability to create a device, ideally compatible with your hand drill. In the presence of an unnecessary photovoller, a microscope or other mechanism in the house (shed, the garage), the task is simplified.
Homemade Stand from the Old Microscope
It remains only to adapt to the product drill. If there is no such bonus - the stand is made from scratch.
How to make a drill machine using branded materials
What should the guide stand for hand drill?
Stable Stanina
It is desirable with the possibility of installing a vice or other adaptation that holds the workpiece. At home is made of thick chipboard, plywood, or textolite. In the center of the axis installed drill, it is necessary to leave the hole with a diameter of a couple of centimeters.
Description of the necessary parts of a drill drill
Guide vertical stand
Here the fantasy developers are unlimited. It can be a bar, a plywood plate, a metal profile or tube.
The main principle in the manufacture - a strict vertical in relation to the supporting bed. Otherwise, the drill will deviate from rectilinear movement, spoil the workpiece and break.
Stroke mechanism
There may be a lever type, or use a pair of a rack gear. It basically does not matter what kind of design to choose. It is important to comply with the principle of the availability of materials, otherwise it may be that it is cheaper to purchase a finished product.

Moreover, not only drill to the workpiece can be supplied. Sometimes it is convenient to raise the product to the drill. For example - on compact models.
Manual Drill Bracket
The perfect solution is to use a seating pad for a drill with a clamp capture. It covers the shaft bearing, and is optimally suitable for centering the entire structure.
»From the material presented by the author, you will learn how to independently make a budget drilling machine from a conventional electric drill.
Each master person would like to have similar machines in his farm, because in comparison with factory analogues will cost tens of times cheaper, and if all parts and components are available, it is generally free.
The author of this machine is Igor Stasyuk, for which he has been thank you very much, shared step-by-step photos of the assembly of the machine with the people. The design is quite interesting and at the same time simple. On the base of the metal sheet 3 mm, the corners and 4 legs were welded, the rod of 500 mm is welded from the proficate pipe of the square section, the slider is made of 2 x corner-boiled corner and put on the lifting column with the gap, so that the slider can move along the column up and down. The lifting mechanism is activated due to the cable of the tight point of the top point to the bottom, and the cable makes several turns on the slider.
And so, let's carefully consider what specifically needed the author to assemble the machine? As well as the whole phased process.

The process of creating a drill drill machine.
And so, the first thing the author manufactures the base of the machine from a sheet metal 3 mm, cuts off the workpiece with the help of a grinder (ESM) and in the lower part, weld 2 corners and 4 legs made of steel rods or fittings. The length of the legs should be the same, in order not to skew the bed.
We wore corners and legs.
Making a slider! 2 corners are taken and applied to the professional pipe of the square section that will serve as a lifting column and are tightened with clamp.
At the edges, it is grabbed by welding in order to simply push it while, and then specifically to slaughter a normal seam.
That's actually such a workpiece turned out.
The lifting column is made from the corner of the square section of 500 mm long.
A bracket with a moving shaft on which the cable turns will be made on the casing body.
A thread is cut in the drilled hole.
The handles of the lifting mechanism are made of reinforcement.
On the shaft there is such a head that will be the base for the handles.
And so, 3 handles are brewed for the convenience of lifting and lowering the drill through the mechanism.
Installed on the lifting column.
At the end of the cable there is such a loop.
The principle of lifting hope is understandable and without explanation)
A square tube is welded to the corner.
That actually such a fastening for the electric drill turned out.
Then the drill is installed and fixed with the bolt clamp and nuts.
Now let's return to the lifting mechanism.
In the upper part of the lifting column, the nut and the bolt is twisted into it, the cable is fixed on the bolt itself and when spinning and unscrewing the bolt occurs the cable tint to the optimal norm.
Moving nodes are preferably pre-lubricated with solidol or lithol.
These small testicles can be purchased in the construction store in the Tools section.
All items were primed by a master using sandpaper, and then painted.
It is not necessary to spend money on a desktop drilling machine, because it is not so difficult to make it yourself. To do this, you will need to purchase, make or use the former use of items. We will tell you about creating several designs, and you can pick up your model for assembly.
Drill is almost every host building or repairing his home or apartment that is repaired by household and garden technology, various crafts from metal and wood. But to perform some operations, the drill is not enough: you need special accuracy, you need to drill a hole at a right angle in a thick board or just want to facilitate your work. This will require a machine that can be performed on the basis of various drives, parts of machinery or household appliances, other infrident material.
The type of drive is a fundamental difference in the designs of homemade drilling machines. Some of them are made using a drill, mainly electric, others - using engines, most often - from unnecessary home appliances.
Desktop drilling machine
The most common design can be considered a machine made of manual or electric drill, which can be removable, to be able to use it outside the machine, and stationary. In the latter case, the inclusion device can be transferred to the bed for greater convenience.
Main elements of the machine
The main elements of the machine are:
- drill;
- base;
- rack;
- fastening a drill;
- mechanism feed.
The base or bed can be made of solid solid wood, furniture shield or chipboard. Some prefer a metal plate, a chawler or brand as the base. The bed must be massive to ensure the stability of the design and compensate for vibration when drilling to obtain neat and accurate holes. The size of a tree of wood is at least 600x600x30 mm, from steel sheet - 500x500x15 mm. For greater stability, the base can be made with eyelets or holes for the bolts and attach it to the workbench.
The rack can be made of a bar, round or square in the section of the steel pipe. Some masters as a base and racks are used by the framework of an old photographer, a non-bandic school microscope, other details that have a suitable configuration, strength and mass.
Fastening the drill is carried out with the help of clamps or brackets with a hole in the center. The bracket is reliable and gives greater accuracy when drilling.
Features of the constructions of the drill feed mechanism
The feeding mechanism is needed for vertical movement drill along the rack and maybe:
- spring;
- hinged;
- design by type of screw jack.
Depending on the accepted type of mechanism, the type and device of the rack will also differ.
In the drawings and photos, the main designs of desktop drilling machines, which can be made from electrical and hand drills are given.

Machine based on steering rack of a passenger car
The steering rail for the car and drill is quite massive products, so the bed must also be massive and, desirable, with the possibility of fixing the machine on the workbench. All items are performed on welding, since the connection on bolts and screws may be insufficient.
The bed and the support rack are welded from channels or other suitable rolled products, a thickness of about 5 mm. The steering rail is fixed on the rack, which should be longer than the rail by 70-80 mm, through the handwoods of the steering column.
To make it more convenient to use the machine, drill control is carried out in a separate unit.

The order of assembling drilling tabletops:
- preparation of all elements;
- fastening the rack to the bed (check vertical!);
- assembly of the movement mechanism;
- fastening the mechanism to the rack;
- fastening a drill (check vertical!).
All mounts must be made as reliable as possible. Steel unintended structures are desirable to connect welding. When using any kind of guides, you need to make sure that the transverse backlash is not formed when moving.
Tip! For fixing the part in which the hole is drilled, the machine can be equipped with visits.
You can also find ready-made racks for a drill. When buying, you need to pay attention to the mass of the design and the size of the working surface. Lights (up to 3 kg) and inexpensive (up to 1.5 thousand rubles) The racks are suitable for performing holes in a thin plywood sheet.
Drilling machine using asynchronous engine
If there is no drill in the farm or it is not desirable to use it in the machine, you can perform a design based on an asynchronous engine, for example, from the old washing machine. The scheme and the process of manufacturing such a machine are quite complex, so it is better to make a master with sufficient experience of performing turning and milling works, the assembly of electricity.
