The efficiency and accuracy of machining a part largely depends on the quality of the machine. Properly selected mechanism serves as a guarantee of product compliance with all specified standards and tolerances. Important role in compliance with the drilling technology, the coordinate table plays.

Concept and types

The table is a manipulator for fixing the workpiece to be processed. Outwardly, it looks like a plate with the possibility of fixing the part using:

• mechanical method;
• vacuum method;
• own weight of the workpiece.

Products come with one, two and three degrees of freedom. This means that the feed is carried out along the X, Y, Z coordinates. For drilling flat parts, horizontal movements are sufficient. With a bulky product or a fixed drill, a vertical movement of the table is necessary.

For large industrial drilling installations long coordinate areas are made. They are equipped with their own installation frame. On such a device, both the part and the processing unit itself are mounted. The table for small machines is made with fastening to the device or on a workbench surface.

By setting the table in motion, the design can be:

• mechanical;
• electric;

The latter type is the most accurate, but the cost of such a device is significant.

Manufacturing of load-bearing elements

The materials for the manufacture of the skeleton of the table are:

• cast iron;
• metal;
• aluminum.

The latter material is used for circuits with light loads and low torsional forces. This option is acceptable when drilling wood or plastic.

Extruded aluminum profile frame, mounted on threaded connections. Thus, it turns out solid foundation. Advantages of the material in:

• low weight;
• availability;
• ease of installation.

Many companies produce ready-made kits for assembling tables with their own hands.

Cast base structures are often cast iron. Their weight is significant, but the efforts that they are able to withstand are quite high. These tables are used for large volumes production. Installation is carried out on the foundation, permanently.

The welded bed is the best option as for production capacity, and for home use. The main thing is to reduce the weld stresses of the metal by releasing when welding with your own hands. Otherwise, when the engine is gaining speed, cracks may appear in the frame.

Drilling machines use two technological schemes table:

• cross;
• portal.

The first is used for bulk workpieces. It makes it possible to carry out other manipulations on the fixed workpiece. Access to the part with this scheme is provided from three sides.

The portal scheme is used when drilling flat products. It is easier to manufacture and is characterized by increased processing accuracy.

Selection of guides

From right choice and fastening of the movement guides of the table surface depends on the accuracy of processing. Rail and cylindrical elements are used. They are produced with carriage superstructure and mounted bearing units.

The choice of the type of table guides depends on the type of drive. The part under consideration works to overcome the friction force. If you need high precision in movement, it is better to choose plain bearings. Rolling bearings reduce friction but create a lot of backlash.

By type of carriage guides are:

• with an enlarged flange, for fastening to the bottom of the table;
• flangeless for conventional mounting to top threaded holes.

When making your own hands, you can order rails with a stainless coating. They have a longer service life and longer abrasion resistance.

Types of gears for table movement

With a small desktop machine, the movement of the table is carried out mechanically. But the greater the speed, accuracy and performance required, the more carefully the type of drive is chosen. Mostly electric motors are used.

The essence of the operation of the unit is to convert the rotational operation of the engine into the translational movement of the table plane. There are three types of transfers:

• rack and pinion;
• belt;
• ball screw.

The choice of node type is made based on:

• workpiece movement speed;
• machine engine power;
• required processing accuracy.

Machining accuracy with various transmission units

Ball screw advantages:

• the possibility of high-precision processing;
• small backlash;
• smooth movement of the table;
• noiselessness of work;
• ability to take on heavy loads.

A significant disadvantage is the limited feed rate. The decrease in speed is especially pronounced with a propeller length of more than 1500 mm. Approximate calculation of speed: for a drive with a power of 1 kW, the rotation speed is 3000 rpm. With a screw pitch of 10 mm, the transmission speed is 0.5 m/s. In this case, 3 m will be covered in 6 seconds.

Another disadvantage is the high cost. You can reduce the cost of the project by using a connection with a screw and nut. In this case, it is necessary to ensure constant lubrication of the assembly.

In drilling machines of a new generation, lubrication of the movable mechanisms of the coordinate surface is carried out automatically. Temperature sensors are built into the device important details.

With rack and pinion transmission, high speed and sufficient accuracy are ensured. The disadvantage is high degree backlash when transferring forces from the drive.

Installing a belt is the most budgetary and common way to create a table with your own hands. The low cost of a belt drive and feed speed up to 1 m/s is offset by the following disadvantages:

• rapid wear;
• loss of tension due to stretching;
• the possibility of breaking during acceleration;
• low precision work.

When buying a coordinate table for drilling or do-it-yourself installation, you must take into account the working conditions. The ratio of all mechanisms by parameters: workload, service life, heating and cooling, will give good result at work. This is especially important when self-manufacturing from improvised materials.

How to make a coordinate table with your own hands

The quality of processing often depends on the correct location of all structural elements. It is quite difficult to choose the right mechanism in accordance with all the norms and tolerances. An important element the design of metal processing equipment can be called a coordinate table. It is used when processing on drilling, milling equipment for precise positioning of the workpiece during its processing.

Homemade coordinate table

Hardware Definition

Coordinate table - a manipulator that is used to fix the workpiece to be processed. There are several options for the execution of machine tables:

1. vacuum fastening method - is used quite rarely due to the complexity of the design;
2. the mechanical type of fastening is simple in execution, you can do it yourself quickly enough;
3. fastening due to the weight of the workpiece. Using drilling machine can be processed workpieces of large mass. Due to its weight, the base part remains in place even under strong impact.

There are positioning with one, two, three degrees of freedom. This moment determines that the feed of the workpiece can be carried out along three different coordinates. When drilling a flat product, it is enough to move it in just one horizontal plane.

Two main types can be roughly distinguished:

1. Large dimensions. A large coordinate table is created taking into account the fact that the equipment itself, as well as the workpiece, will be installed on it.
2. Coordinate table small overall dimensions mounted on the equipment frame.

There are several control mechanisms by which the coordinate table changes its position:

1. Mechanical drive is quite common. You can make it for a drilling machine with your own hands to establish small-scale production.
2. An electric drive is installed for a drilling machine quite often. It is quite difficult to make it with your own hands, since you need to maintain high precision in manufacturing. For automatic movement, the XY table must have its own power supply.
3. Another separate group can be called a mechanism that works from numerical control.

You can make a small coordinate table with a mechanical drive with your own hands.

Production of homemade versions

When manufacturing, you should initially select the material of manufacture:

1. Cast iron is an expensive, heavy, brittle material. It is rarely used in the manufacture of a drilling machine.
2. Steel is a strong, hard, durable metal, which also has a fairly high cost. Steel can be called the most attractive material.
3. Aluminum is light, fusible, but expensive and soft material. It is quite easy to use in the manufacture of any parts for the machine. As a rule, mini equipment is created using this alloy.

The above materials are selected for a full or mini machine.

Manufacturing of guides

The accuracy of processing depends on the correct choice of guides. With your own hands, you can make the following designs:

1. rail;
2. cylindrical.

They are created with a carriage and bearing assemblies. Guides can be selected depending on the type of drive. Plain bearings are used to achieve the highest machining accuracy. In the case of using a rolling bearing, friction is significantly reduced and the service life of the device is increased, but a significant backlash appears, which reduces the accuracy of processing.

Rail guide design

There are two types of guide carriage:

1. with increased flange dimensions, which allows mounting from below the table;
2. construction without flange fastened from above using the threaded method.

Let us note the point that homemade version guide should be closed with of stainless steel. Stainless coated steel can withstand impact high humidity for a long time.

Drive types

When creating a small machine, a coordinate table with a mechanical feed is often installed. However, there are quite a few types of drive, the choice of which is carried out according to the following criteria:

1. processing speed;
2. positioning accuracy;
3. equipment performance.

In most cases, an electric drive is chosen, during the creation of which a motor is installed.

The essence of this mechanism is to convert rotation into reciprocating motion. The following types of gears are distinguished for the design under consideration:

1. belt;
2. ball screw;
3. rack and pinion.

When creating a drive, a belt drive is often chosen. Homemade mechanism belt type is cheaper than others, but the belt wears out quickly and stretches. Also, belt slippage determines the low accuracy of the moving element. All elements of the coordinate steel are interconnected by a welded method. In this case, the threaded method of connecting certain parts is also used.

Ball screw

In conclusion, it should be noted that homemade construction suitable exclusively for domestic use equipment, since it is almost impossible to achieve the accuracy that industrial models have.

Self-creation of a table for a drilling machine

The coordinate table for the drilling machine helps to make the unit work accurate, smoothly move the workpiece to the desired position, avoid jumps, twisting of the part. The efficiency of work on a machine of any type increases significantly when using a coordinate table, especially a do-it-yourself one.

The coordinate table makes drilling faster, easier and more accurate. If a person has a set of tools and materials at hand, such equipment is easy to do on their own.

Types and purpose

Tables for drilling machines come in several different types, can be made of various materials and operate on different principles. This is a simple fixing device, with the help of which the workpiece is fixed in the desired position.

Coordinate table model

With the help of a table during processing, the part is able to change its position and its angle, manipulation allows you to perform different types processing without removing or moving the part. Methods for fixing equipment are as follows:

• using vacuum and differential pressure;
• mechanical devices;
• the part is held on the table independently due to its large weight.

For amateurs who are going to make a table for a drilling machine with their own hands, the second fixation option is most suitable.

Workpiece to be clamped in different installations has an unequal number of degrees of freedom - two or three. In the first case, she is able to move only along the X and Y coordinates, in the second, the ability to move up, down, or along the Z coordinate is added. For home use, two degrees of freedom is enough.

Equipment use

Before starting the operation of the coordinate base, the foreman is obliged to study the safety rules, equipment features, as well as the requirements for lighting in the room where the work takes place.

Bringing the table into action is implemented in the main ways:

• mechanical movement;
• usage electric drive;
• installation of CNC equipment.

The first or second option, when implemented with your own hands, will be the most suitable.

Separately, it is worth mentioning such design options as a turntable and a cross.

The first is able to rotate around its own axis and is the maximum convenient option, if you need to machine parts with axial symmetry, round and disc-shaped workpieces.

Cross table for drilling machine is more common in everyday use and provides the ability to move the workpiece in two directions: X and Y.

base material

Before starting to create a device, you need to think about what materials and spare parts to use. Preliminary preparation necessary so that they can give the future creation the following characteristics:

• Normal working weight, so that one person can work with such a table without tangible difficulty.
• Ease and versatility of installation. good product must fit under different types drilling equipment.
• Maximum cost savings in production. If the development turns out to be too expensive, then isn't it easier to buy a ready-made item.

Most often, these requirements are met by such common and economical options:

• steel;
• metal;
• cast iron;
• aluminum;
• duralumin.

If the table is needed mainly for drilling soft materials(wood, plastic), then aluminum would be the best option. It is extremely lightweight and has sufficient strength.

If you have to work with metals, drill serious details to a relatively large depth, then you will need something more durable - steel, cast iron, iron. These are heavy materials, but the loads they can withstand are impressive.

Guides

Of particular importance in the design of the device being developed are the so-called guides - components along which the table moves in the necessary directions.

The better they are made, the more accurately the specialist will work on the machine, set the position of the workpiece being processed and it will be easier to move it to the right place, apply filler materials and perform other necessary actions.

Guides of two types are used: cylindrical type and rail. It is difficult to say which of them is more efficient - with high-quality implementation, both options show themselves worthy in work.

In order for the sliding of the guides to be as smooth and accurate as possible, it is necessary to use special carriages and bearings. If the requirements for the accuracy of the equipment are not too high, then rolling bearings are quite suitable, otherwise plain bearings should be used.

Rolling bearings will create a small amount of play, but in typical applications this is not a big problem.

For smooth sliding of the guides, the use of rolling bearings is possible.

When making a product with your own hands, you need to choose the option that is most suitable for future tasks.

Movement transmission mechanism

The most important part of the future device, no matter whether it is a rotary table for a drilling machine or a cross version, is the mechanism for transmitting movement from the control knobs to the device.

It is best to drive with mechanical type movement, they are manually controlled. In this way, specialists can achieve greater accuracy of movements, High Quality work being performed.

The components of the motion transmission mechanism are:

• reiki and gear wheels, gears;
• belt mechanisms;
• ball screws.

Ball Screws

Experts advise choosing the latter type of mechanism, especially when it comes to a cross table, it has many significant advantages:

• extremely small backlash of the system;
• the movement of the product is very smooth, without jerks;
• the ball screw operates quietly;
• under significant workloads, it shows high stability.

The minus of the mechanism, experts call the impossibility of achieving a high speed of work, but if a cross table for a drilling machine is considered, then here high speed usually not required.

To save money, the master needs to try to implement belt drives. They are simple and affordable, but have disadvantages:

• low accuracy;
• rapid wear;

As a conclusion, we note that if a person decides to make a table for a drilling machine with his own hands, then there is nothing fundamentally unrealistic in this. An elementary set of material and tools will help to quickly implement the task. The task for the specialist is to choose right kind design and qualitatively manufacture all the critical components of the future device.
