摘 要: 通过对 2 5台国产数控 (ComputerizedNumericalControl,CNC)轴承磨床的故障数据两年多的跟踪记录 ,获得了较为丰富准确的CNC轴承磨床可靠性数据 ,并基于大型关系型数据库技术建立了CNC轴承磨床可靠性数据库 ,对国产数控轴承磨床的故障部位、故障模式及故障原因进行了详细的统计分析 ,指出了数控轴承磨床的薄弱环节及其潜在弱点 。 Failure data of 25 CNC bearing grinding machines have been collected over a period of two years, and the data base of reliability has been built based on Sybase. The failure positions, failure modes and failure causes of CNC bearing grinding machine are statistically analyzed in details. And the weakest link of CNC bearing grinding machine is pointed out, so as to provide a basis for the reliability analyses and design.
