XXX 年毕业论文华中数控故障诊断与维护关键词：华中数控机床、故障、诊断、修理Abstract：Since the computer technology is applied to machine tool.Nearly half a century, the CNC system has gone through two stages and six generations of development. Application of CNC technology not only to the traditional manufacturing industries has brought revolutionary changes in the manufacturing sector as a symbol of industrialization, and with the continuous development of CNC technology and the expansion of application fields, it is the people's livelihood, some important industries ,For example, IT, the development of automotive, light industrial, medical, etc.CNC machine tools are the characteristics of mechanical and electrical integration of typical products in the field of machining, with high precision, high efficiency and high adaptability. CNC machine tools in China's mass, a large number to introduce and promote the use of them to create the conditions for the development of the machinery manufacturing industry, and has brought great economic benefits. Due to the advanced nature of the CNC system, complex and intelligent features, if any part of its failure and failure phenomenon will cause the CNC machine tool downtime, resulting in production to a standstill. Therefore, the failure of the CNC lathe diagnosis and rule out that it is very necessary. Keywords：Huazhong CNC ,Failure, Diagnosis, Maintenance.1. 绪论1.1. 课题背景数控技术是现代机械制造工业的重要技术装备，也是先进制造技术的基础技术装备。随着电子技术的不断进展，数控机床在我国的应用越来越广泛，但由于数控机床系统及其复杂，又因大部分具有技术专利，不提供关键的图样和资料，因此数控机床的修理成为了一个难题。论文将要紧针对华中数控机床进下载后可任意编辑行了简单介绍、故障现象描述或给出典型实例、故障的诊断过程及故障的修理等...
