The pressure control function of cnc lathe machine tool is mainly realized by the pressure control circuit, which is mainly divided into the following categories:

Pressure control circuit of cnc lathe machine tool

1. Working pressure control circuit

In order to obtain a stable working pressure for the pneumatic system, it is necessary to control the secondary pressure of the system, that is, the compressed air controlled by the air source pressure is depressurized and stabilized by the pressure reducing valve as the final working pressure of the system.

This circuit is usually composed of three separation elements, namely air filter, pressure reducing valve and oil mist. Due to the high filtration accuracy of the air filter, a primary coarse filtration device should be installed in front of it, and the oil mist can be installed according to the actual situation. The relative position of the separating elements during combination must be stable and cannot move.

2. Boost circuit

Sometimes, due to the limitation of cylinder size, the required air pressure can not be obtained in some parts, so it is necessary to use supercharger to form supercharging circuit in these parts to achieve supercharging effect by adding low-pressure air and high-pressure oil pressure.

The supercharger used in the pressurization circuit is also divided into single fluid supercharger and dual fluid supercharger. The pressurization circuit using dual fluid supercharger can output more pressure in a narrow space.

3. Other types of pressure control circuits

Common pressure control circuits also include:

An impact control circuit that converts the pressure energy of the air into the kinetic energy of the piston rod through the impact cylinder, so that the piston moves outward at a very fast speed, generates a great impact force and does work externally;

Through the control of solenoid valve, two different pressures are used to drive the movement of double acting cylinder in different directions, so as to achieve the purpose of saving air consumption;

And in some occasions, such as balance system, in order to meet the processing needs of different workpieces with different quality, multi-stage pressure control circuit providing a variety of balance pressure is provided.

The above are several main types of pressure control circuits of cnc lathe machine tools, which play an important role in safe production and energy saving.

Principles of purchasing cnc lathe machine tools

When purchasing cnc lathe machine tools, the selection principle is: comprehensive configuration, give full play to the maximum potential of the host, and comprehensively consider the long-term and short-term benefits.

The selection function of cnc system should be practical, not necessarily too many. Especially the equipment included in the batch production line should be as simple as possible. For machine tools with multiple varieties and small batch production mode, the selection of programming function should be strengthened. Although it can speed up the programming speed, the cost should be increased accordingly.

Another configuration scheme is to simplify the configuration of the programming function of the cnc system, and separately configure the automatic programming machine and the communication interface with the cnc system. The program processing is completed on the programming machine in advance, and then it takes a few minutes to send it to the cnc system, which can further improve the starting rate of the machine tool.
