摘要数控机床是一种技术含量很高的自动化机床，它集机、电、仪于一体，

综合的了计算机技术、自动化技术、伺服驱动、精密测量和精密机械等各个领域
的新技术成果。随着数控车床、数控机床、加工中心等数控加工产品用量的剧增，
培养一大批能够熟练掌握现代数控机床编程、操作和维修的应用型人才的日益
迫切。

不同的数控机床其数控系统虽然在结构和性能上有所区别，但在故障诊

断分析上却有一定的共性，正是在此基础上对数控机床典型故障进行维修。

本设计共计五部分内容，包括数控机床简单介绍，数控机床出现机械结

构故障、电气系统故障、伺服系统故障、可编程控制器模块故障时的现象描述，
故障可能产生原因的理论分析。故障诊断与维修是本设计的重点。

CNC machine tools is a high level of technology automation

machine, which combines mechanical, electrical, instrument into one,
integrated computer technology, automation technology, servo-driven,
precision   measurement   and   precision   machinery,   and   other   fields   of
new technological achievements. With CNC lathes, CNC machine tools,
CNC machining centers, and other dramatic increase in the amount of
processed   products,   and   train   a   large   number   able   to   skillfully
master modern CNC machine tool programming, operation and maintenance
of the application-type talent increasingly urgent.
        Different   NC   Machine   CNC   system   although   its   structure   and
performance are different, but in the analysis of fault diagnosis has
some similarities and it is on this basis, the typical CNC machine
tool fault repair.
The design part of a total of five, including a brief introduction of
CNC machine tools, CNC machine tools in mechanical fault structure,
electrical   system   failures,   servo   system   failures,   programmable
controller   module   describes   the   phenomenon   of   failure,   the   fault
could cause the theoretical analysis. Fault diagnosis and repair is
the focus of this design.
