When some high-power electrical equipment in the same workshop or nearby is frequently started, the grid voltage fluctuates greatly, which will inevitably cause the computer control failure in the CNC machine tool, the stepping motor will fall, etc., as long as a reliable high-voltage power supply or one is configured. The oscilloscope prevents interference. In addition, the prompt, number or content of the self-diagnostic alarm system of the microcomputer can also help to find the fault point quickly. For the screw grinder, when the alarm number is 1, the cam returns to zero for the first time, indicating that the hydraulic pressure is not open or the stepping motor drive power is faulty, causing the cam to return to zero; when the alarm number is 2, it indicates the pressure during the operation of the machine. The lower over-travel switch, at this time the control machine is in the fault lock state, and after the fault is removed, the control machine enters the ready-to-run state. In this way, the order of the first machine and the second can be achieved with half the effort. The maintenance of CNC machine tools should be tested according to the characteristics of the fault, the application test methods, and the step-by-step test. For example, if the fault phenomenon indicates that the software may be out of software (such as parameter confusion or loss), it is necessary to find the parameter settings or parameter record cards randomly brought when the device is installed in the factory, without the need to manually disassemble the unrelated parts. Usually, the change status of the interface signal is used to analyze and determine the hardware failure point. In addition to mastering the above two ideas, it is also necessary to cooperate with the above points and skillfully use some quick, simple and effective inspection methods.
