The method or basis that can be used to judge the failure of the CNC cylindrical grinder is as follows:
Intuitive method: It is mainly to judge through some abnormalities, such as abnormal sound, sparks, odor, abnormal heat, etc., and then make further judgments. This is the simplest method, but it requires maintenance personnel to have certain maintenance experience.

Use the hardware alarm function of the CNC system: use the alarm indicator to roughly determine the location of the fault.

Use the CNC system software alarm function: Generally speaking, CNC systems have automatic diagnosis functions, so that the system can be quickly diagnosed. Once a fault is found, it will be displayed through the display screen or warning light. Therefore, we can use it to determine the location of the fault.

Use the detection terminals on the circuit board: Because there are detection terminals on the circuit board, it is used to detect the circuit voltage and waveform, and check whether the circuit works normally. Therefore, we can use it to judge the fault.
