数控砂带磨床故障分析

摘要

为了研究某型号数控砂带磨床的可靠性水平,找出机床的薄弱环节,对整机进行了故障模式影响及危害性分析；综合故障部位、故障模式、故障原因以及危害度分析的结果,得出砂带磨削装置和数控系统是该机床的薄弱环节,为机床的可靠性设计和分析提供了依据.%In order to study the reliability of a particular model CNC belt grinder and find out the weak link of the machine, the article used FMECA analyze the machine. The article also integrated the results of fault position, fault mode, fault reason and criticality analysis, conclued that the abrasive belt grinding unit and the numerical control system are the weak link of the machine. So that it can provide basis for the reliability design and analysis of the machine.
