Hard rail CNC machine tools and ordinary lathe advantages are different, now look at the advantages of CNC equipment more obvious, batch product processing is naturally higher numerical control, precision is also better numerical control, production efficiency CNC is much higher than the general car. It is a full-function CNC machine tool, set milling, boring and other high-tech functions in one, so that high-speed CNC machine tools have a variety of processing technology. The maintenance technology of hard rail CNC machine tool can not only ensure the normal operation of CNC equipment, but also promote the development and improvement of CNC technology. Therefore, it is of great significance to study and diagnose the fault of CNC machine tool and routine treatment.

1, to investigate the fault phenomenon, we must first investigate the operator, the whole process of destruction, in detail, what phenomenon to take what measures, etc. Then a detailed investigation is carried out on the spot.

2, source failure discovery, open the mind, whether integrated electrical and mechanical, hydraulic, or, as far as possible the cause of the failure listed. Then, comprehensive evaluation and optimization to determine the reasons for possible failure.
