摘要
基于功能结构树,根据某数控磨床的故障数据,对其故障部位及故障原因进行了分析。针对发生故障率较高的子系统———高频电主轴进行深入研究,找出其故障发生的主要原因是元器件烧坏,并提出了相应的可靠性改进措施,为数控机床的可靠性设计和分析提供了依据。
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.
