The maintenance method of hardware and system in CNC machine tool system

In the system of CNC machine tools, the hardware and maintenance of the system are the content that has not been mentioned before, so we need to understand and master it, because it is about CNC machine tools, and CNC machine tools are used in mechanical processing plants. One of the equipment, then let's look at the specific content below.
When the system fails, the first visual inspection should be performed. The inspection objects include connections, connectors, vulnerable parts, components that require regular maintenance, and power supply voltage. These should be checked one by one and eliminated one by one. In order to find out and solve the problem in time. The solution methods are mainly as follows: failure phenomenon analysis method: According to the characteristics of the failure, organize relevant personnel to conduct consultations, analyze the abnormal phenomenon, find out the rules and clues of the failure, and take preventive measures if necessary Measures to prevent the failure from happening again. System analysis method: Determine the faulty part of the system, and consider each box in the control system block diagram separately. This method can ignore the internal structure and only consider the input and output. Signal tracking method: According to some characteristics, parameters, etc. of the signal, compared with the normal situation, whether there is a difference. Static measurement method: Use a multimeter to measure the on-line resistance of components and the PN junction voltage of transistors, and use a transistor tester to measure the quality of components. Dynamic measurement method: After visual inspection and static measurement, add AC and DC voltage, synchronous voltage and input signal lights to the circuit board, and then use a multimeter and other instruments to conduct a comprehensive analysis and diagnosis of its output voltage, current, and waveform. Troubleshoot.
