With CNC lathes, CNC machine tools, CNC machining centers, and other dramatic increase in the amount of processed products, and train a large number able to skillfully master modern CNC machine tool programming, operation and maintenance of the application-type talent increasingly urgent.  Different NC Machine CNC system although its structure and performance are different, but in the analysis of fault diagnosis has some similarities and it is on this basis, the typical CNC machine tool fault repair. The design part of a total of five, including a brief introduction of CNC machine tools, CNC machine tools in mechanical fault structure, electrical system failures, servo system failures, programmable controller module describes the phenomenon of failure, the fault could cause the theoretical analysis. Fault diagnosis and repair is the focus of this design. 故障分析 故障维修 本设计是为了能够让维修人员更加快速准确
