Host failure

The main engine of CNC machine tools usually refers to the machinery, lubrication, cooling, chip removal, hydraulic, pneumatic and protection parts of CNC machine tools. Common host faults are as follows:

1) Mechanical transmission failure caused by improper installation, debugging, operation and use of mechanical parts

2) Failure caused by interference of moving parts such as guide rail and spindle and excessive friction

3) Failure caused by damage to mechanical parts, poor connection, etc

The main engine failure is mainly manifested as large transmission noise, poor processing accuracy, large running resistance, mechanical parts do not operate, mechanical parts damage and so on. Poor lubrication, pipeline blockage and poor sealing of hydraulic and pneumatic systems are common causes of failure of the main engine. Regular maintenance of CNC machine tools. Controlling and eradicating the occurrence of "three leaks" is an important measure to reduce the partial failure of the host.

Electrical control system failure

Electrical control system fault from the type of components used. According to common habits, electrical control system failures are usually divided into two categories of "weak current" failures and "strong current" failures.

The "weak current" part refers to the control part mainly composed of electronic components and integrated circuits in the control system. The weak current part of CNC machine tool includes CNC, PLC, MDI/ CRT and servo drive unit, output unit and so on.

"Weak current" fault is divided into hardware fault and software fault. Hardware failure refers to the failure of integrated circuit chips, discrete electronic components, connectors and external connection components of the above parts. Software failure refers to the operation of the hardware under normal conditions, data loss and other failures, common are. Processing program error, system program and parameter change or loss, computer calculation error, etc.
