For housework, the functions of a drill may be sufficient, but to improve the quality and productivity of work, more precise equipment may be needed. One of the most popular varieties is a DIY 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. It's important to understand general principle functioning and further determine the optimal scheme of the homemade design.

Basics functional purpose consists of forming holes various types. Depending on the configuration of the equipment, there may be drawings of vertical drilling, jig boring, radial drilling, and filler models. The difference between them is the ability to change the direction of action cutting tool. For household needs Most often, a mini vertical drilling machine is made by hand.

Structurally, it should consist of the following elements:

• bed. The supporting part on which the vertical stand 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, to produce a homemade drilling machine with your own hands, they use standard drawings in which the electric motor is replaced with an electric drill. This allows you to reduce the labor intensity of work. However, such designs are designed only for small loads.

Before independent production mini-machine, you should decide on the type of wood and metal work to be performed. The characteristics of the equipment will depend on this.

Homemade drilling machine from a drill

The most popular model currently is a mini drilling machine made from a drill. To make it at home, you only need to make a frame and a stand.

In some cases, it can be done without the use of homemade elements. To do this you will need a factory stand and a drill. There is no need to draw up drawings for this, however, such a design has one significant drawback- big backlash. During work, the cutting tool shifts relative to the drilling site. This must be considered before doing drilling machine.

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

• You can use the steering rack to raise and lower smoothly. Alternative option is an adaptation of a mechanical jack;
• The support table and stand are made of steel channels and angles. It is important to ensure sufficient mass of the lower part of the structure for maximum stability of the machine during operation;
• separate control unit. Turning the drill on and off will be awkward. Therefore, it is recommended to install a standard switch on the side of the mini drilling machine.

During the execution of work, maximum accuracy of mating of structural elements should be ensured. The angle between the support post and the table should be 90 degrees. For filler models minimum thickness 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 allow you to achieve maximum processing accuracy.

Homemade high power machine

If it has unsatisfactory parameters, you can consider other drawings of a similar design. Their difference from the model discussed above is the use of an electric motor as the main power plant.

Making such a design at home will be problematic, as it will require a lot of time and effort. An electric motor can be made from a washing machine. The chuck for attaching the cutting tool is not made with your own hands; it is taken from an old machine. Additionally, pulleys are 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 to provide for the possibility of changing its speed. To do this, you can install a gearbox.

As additional equipment You can make a vice at home. They will clamp the parts to perform precise machining.

The video shows the exact diagram and drawings for making a mini-drilling machine with your own hands:

Examples of drawings and finished machines

You don't have to spend money on a benchtop drill press because it's not that difficult to make your own. To do this, you will need to purchase, manufacture or use used parts. We will tell you about creating several designs, and you can choose your model for assembly.

Almost every owner who is building or renovating his house or apartment, repairing household and garden equipment, various crafts made of metal and wood. But for some operations, a drill is not enough: you need special precision, you want to drill a hole at a right angle in a thick board, or you just want to make your work easier. To do this, you will need a machine that can be made on the basis of various drives, machine parts or household appliances, other available material.

The type of drive is a fundamental difference in the designs of homemade drilling machines. Some of them are made using a drill, mostly electric, others using motors, most often from unnecessary household appliances.

Tabletop drilling machine made from drill

The most common design can be considered a machine made from a hand or electric drill, which can be made removable, so that it can be used outside the machine, or stationary. In the latter case, the switching device can be moved to the frame for greater convenience.

Main elements of the machine

The main elements of the machine are:

• drill;
• base;
• rack;
• drill mount;
• feed mechanism.

The base or frame can be made from a solid cut hardwood, furniture board or chipboard. Some people prefer a metal plate, channel or tee as a base. The bed must be massive to ensure structural stability and compensate for vibrations during drilling to produce neat and accurate holes. The size of the frame made of wood is at least 600x600x30 mm, of sheet steel - 500x500x15 mm. For greater stability, the base can be made with eyes or holes for bolts and attached to the workbench.

The stand can be made of timber, round or square steel pipe. Some craftsmen use the frame of an old photographic enlarger, a substandard school microscope, and other parts that have a suitable configuration, strength and weight as a base and stand.

The drill is secured using clamps or brackets with a hole in the center. The bracket is more reliable and provides greater accuracy when drilling.

Design features of the drill feed mechanism

The feed mechanism is needed to move the drill vertically along the stand and can be:

• spring;
• articulated;
• screw jack type design.

Depending on the type of mechanism adopted, the type and structure of the rack will also differ.

The drawings and photos show the basic designs of tabletop drilling machines, which can be made from electrical and hand drill.

Machine based on the steering rack of a passenger car

A steering rack for a car and a drill are quite massive products, so the frame should also be massive and, preferably, with the ability to attach the machine to a workbench. All elements are welded, since connections with bolts and screws may not be sufficient.

The frame and support post are welded from channels or other suitable rolled products, about 5 mm thick. The steering rack is secured to a stand, which should be 70-80 mm longer than the rack, through the eyes of the steering column.

To make the machine more convenient to use, the drill control is placed in a separate unit.

Assembly procedure for tabletop drilling machines:

• preparation of all elements;
• attaching the stand to the frame (check verticality!);
• assembly of the movement mechanism;
• fastening the mechanism to the rack;
• fastening the drill (check verticality!).

All fastenings must be made as securely as possible. It is advisable to join one-piece steel structures by welding. When using any kind of guides, you need to make sure that there is no lateral play during movement.

Advice! To fix the part in which the hole is drilled, the machine can be equipped with a vice.

You can also find ready-made stands for drills on sale. When purchasing, you need to pay attention to the weight of the structure and size work surface. Lightweight (up to 3 kg) and inexpensive (up to 1.5 thousand rubles) racks are suitable for making holes in a thin plywood sheet.

Drilling machine using asynchronous motor

If there is no drill on the farm or it is not desirable to use it in the machine, you can make a design based on an asynchronous motor, for example, from an old washing machine. The design and manufacturing process of such a machine are quite complex, so it is best to make it by a craftsman with sufficient experience in turning and milling work, and assembling electrical circuits.

Mini-machines for drilling circuit boards by radio amateurs also borrow the drive from various low-power devices. In this case, cutters for cutting photographs are used as levers, soldering irons, and collet pencils instead of a chuck. The drilling site is illuminated with LED flashlights—there are plenty of opportunities for technical creativity.

It does not always make sense or expediency to buy a factory-made drilling machine. You can make a vertical drilling machine from a drill with your own hands. To do this you will need a drill and materials to make a stand. Such equipment is recommended for use in home workshops or garages, when drilling is not the main operation or is performed quite rarely and the accuracy of the hole can be neglected.

To speed up the process, just buy a specialized stand for a drill at a tool store. The result is something like a household level vertical drilling machine, which is not inferior in drilling accuracy to machines for home workshops.

The photo shows drill stands factory production. They can be purchased at any online tool store at prices starting from $200.

The article is intended to give you ideas on how to make a drilling machine yourself from a drill, so we do not give a clear algorithm for its manufacture, because it is made from scrap materials: some craftsmen will have it, others will not. Therefore, we give basic ideas, and everyone will apply their own constructive solutions and make your own vertical homemade drilling machine.

If you are not looking for easy ways, then we will make a homemade stand. The stand can be made of wood or metal. Wood will be cheaper and easier to manufacture, but durability will suffer.

Metal ones are more complex, but have an incomparably longer service life and strength characteristics. The choice of stand material also depends on the workpieces being processed: when constantly drilling metal, it is better to make a metal one.

Machine assembly

Metal racks are assembled from corners for the carriage, square pipe 50x50 for the stand and 10x10 for the drill bracket, strip for the base and lugs. The base and bracket are welded, after which all elements are assembled and bolted together. It is recommended to make several brackets with different adapters (clamping rings) for different types drills. The carriage moves along the rod using a steel cable wound around the handle drum. So that the carriage does not have play and does not fall under own weight down, drill it, cut a thread and tighten a bolt (or several bolts). This selects the backlash between the carriage and the stand of the future drilling machine. The handle for moving the carriage is made from rolled products with a diameter of 6 - 8 mm.

Having several brackets with different clamping rings allows you to flexibly select drills and process almost any material.

In the future, home-made equipment can be upgraded and modified, for example, by marking or installing a scale that will indicate the length of movement of the carriage. This helps when drilling blind holes.

There are several mounting methods:

• several clamps;
• on metal bracket in the hole under the neck of the drill.

The easiest way to make a homemade drilling structure at home

A homemade drilling machine made from a drill will never replace a factory one and will always be inferior in build quality and drilling accuracy. The main advantage of homemade is low price, the ability to drill holes when the factory machine is not available for one reason or another.

It is advisable to make a drilling machine with your own hands in situations where there is a need to drill holes in parts in a home workshop or garage various configurations, as well as made from different materials. It should be noted that such a device makes it possible to obtain holes with sufficient high level quality.

When you need a homemade drilling machine

In production or repair enterprises, where the drilling operation is considered the most common, a special device is used to perform it, the models of which may have different functionality. So, it can be a compact tabletop drilling machine, distinguished simplest design, or equipment equipped with several working spindles and numerical control.

For drilling holes in various materials, which is performed in a home workshop or garage, you can use home-made equipment. Naturally, for use at home you need a simple device that can be made from components and materials found in almost any garage or home workshop.

And in this article we will not leave unanswered the question of how to make a drilling machine at home, while spending a minimum of money. The drawings and experience of many craftsmen who have already walked this path will help us with this.

The need for such mini drilling equipment for metal, wood or plastic most often arises among those who are accustomed to independently performing various renovation work in your house or apartment. Also, quite often radio amateurs are puzzled by the construction.

It would seem that a conventional drill can be used to perform such an operation, but such a tool is not always able to provide the required quality and accuracy of drilling operations. Homemade, in addition to its compactness, has one more important quality: It can accommodate different types of drills.

Drilling machine from a conventional drill

To make a small but functional drilling machine for your home workshop, you don’t need to purchase special materials and components. The design of such a convenient and useful desktop device contains the following components:

• the base, which is also called the bed;
• a mechanism that ensures rotation of the working tool (a conventional drill can be used as such a mechanism);
• device for providing supply;
• a vertical stand on which the rotation mechanism is fixed.

The stand on which the drill will be mounted can be made from chipboard sheet. This material is quite capable of supporting the weight of such a device. The bed of such a mini-machine should be more massive, since it protects the entire structure from vibrations, which can negatively affect both the quality and accuracy of the resulting hole, and the comfort of work.

As a material for this frame, you can use an ordinary furniture board, the thickness of which is more than 2 cm. It is most convenient to use the base of an old photographic enlarger for this, slightly modifying its design. Sometimes an old microscope is used, but this is a rather rare option, since such a unit will not be large enough and its use will be limited.

The quality and accuracy that a homemade drilling machine will provide depends primarily on how correctly and reliably the connection of its base and vertical stand. Important elements Such a micro machine consists of two guides along which the block with the drill attached to it will move. Such guides are best made from two strips of steel, which must be securely screwed to the rack using screws.

When making the block, it is advisable to use steel clamps that will securely fix the drill on it. In addition, in order to avoid unwanted vibration processes when drilling, a thick rubber gasket must be installed at the junction of the block and the drill.

After this, you need to make a feed mechanism for such a mini machine, which should ensure the movement of the electric drill in the vertical direction. The manufacturing schemes for such a mechanism may be different, but it traditionally contains in its design a lever and a spring, which is attached at one end to the stand, and at the other to the block with the drill. This spring gives the feed mechanism greater rigidity.

A drilling machine made from a drill, which is not planned to be removed from it, can be made more convenient to use if you disassemble the original switch of the drill and mount a separate button on the frame of the mini equipment. This button will always be at your fingertips and will allow you to quickly turn the device on and off. As you can see, it’s not at all difficult to make a drilling machine from a drill; all you need to do is read these instructions carefully or watch the training videos in this article.

An example of a drill machine in more detail

As an example, let's look in more detail at one of the options for a homemade drill assembled at home.

Manufacturing a machine using an asynchronous motor

Lack of excess electric drill- this is not a reason to abandon the idea of ​​​​making a drilling machine with your own hands. To drive the rotation mechanism of such equipment, you can use any Electrical engine. Such engines, which were previously installed on various techniques, will probably be found in the garage or workshop of any home craftsman.

Asynchronous motors, which are equipped with washing machines. If you have such a motor, you can confidently use it to make home drilling equipment. Making drilling equipment with such an engine at home is somewhat more difficult than using a drill, but the power of such a machine will be much higher.

Given the fact that an induction motor weighs more than a conventional drill, you will need a stronger base and stand to accommodate the feed mechanism.

In order for such a mini drilling and attachment machine to vibrate less during operation, it is necessary to install the motor on a powerful base and place it as close to the stand as possible. But here it is important to maintain the correct distance, since the convenience of installing the belt drive depends on it, due to which the rotation from the motor will be transmitted to the drilling head.

In order for you to make such a machine at home, you will need the following structural elements:

• gear;
• a hexagon on which the pulley will be placed;
• two bearings;
• two tubes, one of which must be with internal thread;
• clamping ring, which must be made of durable steel.

The hexagon also connects to metal tube, bearing and clamping ring. Such a connection must be very reliable so that the resulting assembly does not collapse during operation.

The mechanism necessary to ensure the feed of the tool in such a mini machine must consist of a tube on which cuts are first made, and a gear. The tube will move due to the connection of its teeth with these cuts. An axle with a hexagon is then pressed into this tube, the height of which must correspond to the amount of the required tool feed.

Example of a drilling machine with an asynchronous motor

Let's consider one of the very serious options for a homemade drilling machine with asynchronous motor, made clearly not by a newbie. Few home craftsmen would dare to take on such a project, but if, as they say, the urge comes, then nothing is impossible.
