数控机床常见故障分析及诊断方法

Diagnosis Method of Numerical Control Lathe PLC Troubles

针对生产实践中数控机床常出现的故障,本文分析了故障的表现形式,阐述了独立单元分析法、接口信号分析法、PLC程序法、参数检查法等,实践证明这些方法大大提高了维修效率。

To the emergence of the common troubles of the numerical control lathe in produc tion practices, this text analyzes numerical control system troubles, independent analytic ap proach exposition, interface signal analytic approach, PLC procedure law from the expres sion forms of the trouble. Practice has proved these methods have improved efficiency of ma intainance greatly.
