化机数控机床是数字控制机床的简称，是一种装有程序控制系统的自动床。该控制系统能够逻辑地处理具有控制编码或其他符号指令规定的程序，并将其译码，从而使机床动作并加工零件。它自动化程度高 ,结构较复杂的先进加工设备，在机械制造业中获得了广泛的应用。为了提高机床的使用率，文章总结了几种常用的排除数控机床故障的方法，通过实例介绍数控机床故障排除方法的应用，对从事数控技术的人员有参考作用。

-Of CNC machine tools is referred to as the digital control machine tools, and a bed with automatic process control system. The control system is capable of processing logic control codes or other symbols Directive stipulates procedures and decoding, so that the machine action and machined parts. It high degree of automation, the structure is more complex advanced processing equipment, widely used in machinery manufacturing industry. In order to improve the utilization of the machine, the paper summarizes several commonly used method rule out the failure of CNC machine tools, CNC machine tools troubleshooting application of the method, reference personnel engaged in CNC technology is introduced through examples.
