What does CNC machine tool maintenance include?


1, the use of CNC system self-diagnosis function
The general CNC system has a relatively complete self-diagnosis system, whether it is Fanuc system or Siemens system, the CNC system can make a certain range of self-diagnosis for itself or the interface during power-on initialization or operation. Maintenance personnel should be familiar with the system self-diagnosis of various alarm information. According to the manual analysis to determine the scope of the fault, locate the fault components, for the imported CNC system can only be located to the board level, the chip level maintenance can generally rely on the CNC system manufacturer after-sales maintenance department.
2, the use of PLC program logic search.
Now the general CNC control system is equipped with PLC controller, mostly built-in PLC control. Maintenance personnel should analyze the machine tool control electrical equipment according to the ladder diagram, and visually see the status of the CNC system I/O on the CRT. Through the logic analysis of the PLC program, the inlet pump can easily check the problem location, such as the self-diagnosis page in the FANUC-OT system. According to the PLC ladder diagram of the drawings, locate the interface fault of the machine tool and CNC system to determine whether the fault is a mechanical, electrical, hydraulic or pneumatic fault.
3. Fully communicate with the operator on the spot
Field operators are the closest partners of CNC machine tools, and operators are also the first discoverers of various faults. Therefore, when the fault occurs, the maintenance personnel generally do not rush to start, first communicate fully with the operator, to carefully ask the machine when the fault occurs in what working state, the form, the consequences, whether it is misoperation, whether the fault can be reproduced, etc., which helps the maintenance personnel to quickly analyze and judge the cause of the fault.
