What should be done when a CNC grinder malfunctions?
1、 Investigation of the fault site.
When a fault occurs, it is necessary to understand under what circumstances the machine tool fault occurred, what phenomena occurred, and what measures the operator took after the fault occurred. If the fault site is still present, it is necessary to carefully observe and understand the content of the program segment being executed and the alarm content displayed by the self diagnosis in the CNC, and observe the alarm lights on each circuit board. Then press the reset button of the system to see if the fault disappears. If the fault alarm disappears, it is mostly a software fault.
2、 List all possible factors that may cause the malfunction.
The causes of the same malfunction in CNC machine tools may be diverse, including mechanical, electrical, control system, and many other factors. Therefore, when analyzing the malfunction, all relevant factors should be listed.
3、 Method to confirm the cause of applause.
There are various types of CNC systems for CNC machine tools, but regardless of the type of CNC system, the following methods can be used to comprehensively diagnose faults when they occur:
1. Intuitive method.
2. Utilize the hardware alarm function of the numerical control system.
3. Utilize the software alarm function of the numerical control system.
4. Utilize the diagnostic function of status display.
5. When a malfunction occurs, the parameters of the CNC system should be checked in a timely manner.
6. Spare parts replacement method.
7. Utilize the detection terminals on the circuit board.
