The maintenance of CNC machine tools, like other maintenance work, needs to be rigorous and meticulous: to find out the commonality of the microcomputer numerical control system in terms of structure and working principle, and to locate the fault source in stages. Summarize scientific and reasonable fault analysis ideas, the key of which is diagnosis and testing, including the detection of peripheral lines, and strive to locate faults on the board line, and finally locate the fault at the element and device level. The preliminary analysis of the fault is based on the occurrence of the fault phenomenon to determine whether the fault is a general machine tool alarm (operation error, programming error, workbench movement overtravel error, etc.), or reproduce the fault, including various conditions of the machine that cannot be satisfied. (such as insufficient compressed air pressure, insufficient hydraulic system pressure, unstable voltage or high grounding resistance, etc.) are all such faults. Usually there are the following methods: first outside and then inside, first after the machine. Because CNC machine tools are advanced machining equipment with large technical complexity. After the machine is powered, the machine is first checked. The general mechanical fault is relatively intuitive and easy to find. See if the operation is normal, whether the stroke switch is inflexible, pneumatic or hydraulic, or not. If the machine is operating normally, check the electrical aspects. Of course, such checks include power supply voltage, various functional modules, test of parameter setting values, self-diagnosis alarm system prompts, and signal testing between functional modules.
