In Kunshan CNC machine tools, most of the faults have data to check, but there are also some faults. The alarm information provided is more ambiguous or even no alarm at all, or the period of occurrence is long, irregular, irregular, and lookup analysis. Brought a lot of difficulties. For such machine tool failures, it is necessary to analyze the specific situation and carry out patient search, and the comprehensive knowledge of mechanical, electrical and hydraulic aspects is especially needed for inspection. Otherwise, it is difficult to find the real cause of the failure quickly and correctly.
Abnormal machining accuracy: system parameters change or modification, mechanical failure, machine tool electrical parameters are not optimized motor operation abnormality, machine tool position ring abnormality or control logic is not appropriate, is a common cause of abnormal machining accuracy of CNC machine tools in production, find out relevant The fault point is processed and the machine tool can be restored to normal. In production, it is often encountered that the machining accuracy of CNC machine tools is abnormal. Such faults are highly concealed and difficult to diagnose.
