PURPOSE:

Jig grinding machines are designed for grinding complex shapes and holes, where the highest degrees of machining accuracy are required. According to the principle of operation, these machines are very similar to jig boring machines, but the difference is that grinding machines have a higher processing accuracy (much higher than that of a simple milling or turning machine) and the speed of the grinding spindle.

APPLICATION AREA:

Machine tools are used in tool production, the manufacture of dies, dies, the production of complex modern mechanisms, wave gearboxes, products requiring particularly high machining accuracy, etc. In the production of these machines, linear drives, high-speed pneumatic or electric motors and various cooling systems are used, both for the machine itself and for the workpiece.

The machine runs at a high spindle speed. Spindles can be changed depending on the requirements of the processing, in order to achieve an optimal result. Some of the spindles are fixed speed (60,000 rpm), others are adjustable (30,000 to 50,000 rpm) and still others are very high speed (150,000 rpm). The main spindle has a wide range of speeds to ensure the desired result. The machines have standard movement axes (X and Y). All axes are indexed to 0.0001 mm using an electronic flywheel. The machine is equipped with high-precision linear drives. The spindle rotates at variable speed and moves with an accuracy of 0.0001 mm for grinding high-precision holes. Only the use of such technologies will achieve the desired result with precision processing.

More Hide

There are a huge number of technological processes, the implementation of which allows you to get a part with the required dimensions, shape and surface quality. For many years, metal processing plants have used special devices called machines. There are several technological processes, among which we note the processing by grinding. Grinding can change the quality of the surface, as well as its shape, by mechanical action. Over the years of development in the field of metal processing, quite a few varieties of equipment have appeared, each of them has a special scheme of work, which is reflected in the drawing.

Purpose of equipment

A grinding machine is a device that is used to process various products made of metal, wood, plastic and other materials. A few decades ago, the equipment was created for processing with low accuracy, technically the design did not allow to bring the dimensions of the parts to high accuracy, but still the characteristics that the grinding machine possesses made it possible to finish.

The grinding machine can be used to solve the following technological problems:

1. Changes in the shape of the surface of a cylindrical, square and other workpiece. Grinding equipment, depending on the abrasive material, can be used to process various metals, it is possible to remove a relatively small layer of material.
2. Changes in surface roughness is the main purpose for which the grinding machine was created. The device can remove tens of millimeters of metal or other material.
3. In some cases, a grinder is used for sharpening. This is due to the fact that the device is used to remove metal, if the cutting edge is correctly positioned, then it is possible to sharpen.

It is almost impossible to achieve results when using hand tools, as if using grinding equipment. Performance is also very high, there are both domestic and industrial versions. The operation of the device requires maintenance, which should also be taken into account.

Classification

As previously noted, there are quite a few drawings and diagrams that produce a grinding machine. This is due to the fact that the shape and dimensions of the parts determine how the processing will be carried out, and what kind of spindle, grinding equipment will have.

By type of installation, the following classification can be made:

1. Desktop. Modern drawings and diagrams of desktop machines determine that they can be used in everyday life. At the same time, maintenance will not bring many problems, power consumption is negligible, and management is not difficult. However, the desktop version has less performance and functionality.
2. The modern industrial version has high performance, the scheme and drawings of the model determine that the models have compact overall dimensions. Technically, they are more perfect than those models that were produced in factories in the last millennium.
3. A grinding machine made in the factories of the Soviet Union is also often found in workshops. Their drawings and diagrams are studied in educational institutions upon receipt of the appropriate qualification. However, the maintenance of such equipment is much more complicated, since the necessary tools and parts are no longer produced.

By purpose, the following groups can be distinguished:

1. Cylindrical grinding - the most common models that are used for processing cylindrical and conical parts. Such machines are divided into several groups according to the accuracy class. They have been in production since the mid 1990s. Some models were produced for workpieces with high diameter and linear dimensions.
2. Internal grinding models are less common, but all are often used in metalworking factories. Internal grinding machines can be for domestic and industrial purposes, their performance depends on the equipment and the degree of automation of the processing process. Use internal grinding models to change cylindrical internal surfaces, holes of various shapes. Tooling can change the technical characteristics of an internal grinding machine to a large extent.
3. The surface grinding group has a scheme that allows you to carry out work to bring the roughness and dimensions of flat and mating surfaces to the desired values. The spindle in this case is located so that the grinder can be used to carry out work associated with a flat surface.
4. Centerless grinding group for large-scale production. The scheme and drawing, which are characteristic of such a group, cause a simplification of the maintenance process, as well as technical characteristics allow automating the process and increasing productivity.
5. Honing is the process of bringing the dimensions of a surface to a high degree of accuracy, when the deviation is only a few fractions of a millimeter. The layout of all structural elements, which the grinding machine of this group has, allows processing both cylindrical and flat surfaces. With the help of hand tools, it is impossible to achieve such a result, the control allows you to change the processing characteristics depending on the task.

In this case, cylindrical grinding options can be divided into the following groups:

1. universal machines - can be used for grinding various cylindrical and conical workpieces, the characteristics of the models can significantly expand the scope. The control of the universal machine can be carried out mechanically or with the help of an automated CNC system;
2. simple models - grinding equipment that is used for a specific group of workpieces. The scheme and characteristics of simple models determines that only certain groups of parts can be processed when using them. Recently, machines belonging to this group have practically not been produced. This is due to the fact that their purchase is often not justified. Often they are made to order in the organization of mass production.

Considering such a large distribution of cylindrical grinding machines, we will consider the design features. The control of the rotary working table, as well as the characteristic that allows the rotation of the part, determines the versatility of the model. The design scheme has a spindle that can rotate around a vertical axis. Some models have additional headstocks that allow you to change the degree of roughness of holes of various shapes.

Computer numerical control

CNC has been developed over the years in order to increase productivity and simplify the task, to increase the accuracy of the resulting dimensions. The drawings of many parts have dimensions with minimal tolerances; it is impossible to use a hand tool to solve such a problem. Therefore, if the drawings have similar tolerances, a mechanized processing method should be used.

Many problems did not allow the use of numerical control when creating a grinding machine. An example is the lubrication system, as well as the positioning of the spindle. CNC control determines the high-precision positioning of the spindle, automation of the lubrication system.

Despite the huge number of advantages of the CNC system, it is quite difficult to find a design with such automation technology. This is due to the fact that such equipment is used extremely rarely in large-scale and mass production.

The CNC determines the exact positioning of the spindle. However, it should be borne in mind that the spindle must be positioned taking into account the equipment used. Therefore, the drawing indicates what equipment is used for grinding machines.

Maintaining a CNC design is much more difficult, as changes can lead to a malfunction. Adjustment of equipment should be carried out periodically to maintain the accuracy of dimensional changes and the quality of roughness.

There are quite a few varieties of the CNC system, which are divided according to the type of program used to describe the trajectory of the abrasive wheel, describe the spindle speed and feed rate.

Cooling

If lubrication allows to extend the service life of the structure, then cooling significantly increases the service life of the abrasive material. Drawings are created taking into account the fact that during contact with the abrasive material the surface will not heat up, as well as the abrasive material. To do this, the spindle may have a coolant supply system. Household models have a bath of water that will also cool the treatment area.

Maintenance of the cooling system is the need for constant replenishment of the reservoir with coolant.

In conclusion, we note that there are quite a few modern models that have high performance, ease of use, and versatility. Many of them are suitable for domestic and industrial use.

Today, manufacturing enterprises operate in special conditions: the market puts forward strict requirements for them regarding the use of new technologies and automation of the production process. One of the keys to success in many manufacturing industries is the use of CNC machines.

This abbreviation stands for "numerical control". The use of such technological innovations in recent years has made it possible to reduce the cost of production, while increasing its quality, as well as to increase production volumes and reach new profit levels.

What is a CNC machine?

It is difficult to imagine modern technological production devices without a numerical control module. CNC is a computer control system that controls all the processes of the mechanisms on the machine. Efficiency provides a certain set of commands created using special programming languages. Such a unit is also called a CNC machine, which stands for Computer Numerical Control.

All machine tools have a working element: it can be a punch, spindle, drill and other parts, depending on the purpose of the unit. Therefore, there are drilling, turning, grinding, cutting and other types of CNC machines.

The system consists of several important modules:

• operator console (it sets the program of work, turns off and on the device);
• a screen that displays a given program, features of the ongoing technological process;
• controller (contains information about running programs written in a special programming language);
• work programs specified in the system;
• RAM.

It is noteworthy that no special education is required to work with CNC machines. It is enough for the staff to learn how to deal with the software, no specialized skills are required. The system is so smart that information about any malfunctions and failures will be immediately displayed on the display.

Benefits of using CNC machines

The most important plus that has become a reality after the appearance of such units is a high level of automation in production. All parts are manufactured in accordance with the software, and the operator's intervention in the work process is practically leveled. CNC machines can run virtually uninterrupted while maintaining the same high level of product quality:

• Reduced operator time. The operator, as a rule, is involved at the beginning and end of the production cycle - he installs and removes parts, and also launches the desired program. This reduces his participation in the process to a minimum and allows him to simultaneously serve several devices at once.
• Flexible setting. A large number of programs allows you to adjust the production process of various parts. To make changes to the process, it is enough just to change the production program.
• High precision of the final product. Thanks to the software, you can produce high-quality and reliable parts with the same technical characteristics by setting certain device operation parameters.
• Great variety of shapes. Such modern units make it possible to manufacture complex parts, for example, with a complex spatial shape.
• The manufacture of such elements on conventional equipment is rather difficult.
