| Abstract: | Based on the function structure tree and the failure data of a CNC grinding machine, the failure positions and failure causes of the CNC grinding machine were analyzed in this article. The frequent failure position, high- frequency motor built -in spindle, was investigated in detail and found out that the main failure cause of the CNC grinding machine was burning out of components. The corresponding improvement measures were put forward and offered a basis for the reliability design and analysis of CNC machine tool. |
