Multi die punch; Mesh punch; Verify the accuracy and completeness of various situations provided by the operator, so as to verify the accuracy of preliminary judgment. Due to the level of the operator, there are many examples of unclear or even completely inaccurate description of fault conditions. Therefore, after arriving at the site, do not rush to deal with it, and re investigate various conditions carefully, so as not to damage the site and increase the difficulty of troubleshooting.

Determine the cause, check a variety of possible causes, and find out the real cause of the fault. At this time, it is a comprehensive test for the maintenance personnel on the familiarity, knowledge level, practical experience and analysis and judgment ability of the machine tool. Visual inspection method is a necessary method at the beginning of fault analysis, which is to use sensory inspection.

The device inspection method uses conventional electrical instruments to measure the AC and DC power supply voltage of each group and relevant DC and pulse signals, so as to find possible faults. For example, check the power supply with a multimeter and measure the relevant signal status measurement points set on some circuit boards.

Use an oscilloscope to observe the amplitude, phase and even presence of relevant pulsation signals. The faults in PLC program and processing program are usually equipped with alarm display. According to the displayed alarm number, the possible fault causes and troubleshooting methods can be known by comparing with the corresponding diagnosis instruction manual.
