INTRODUCTION Enhancing NC lathe reliability has become the key of survival and development for Numerical control lathe manufacture enterprise. Today machine tool market compete drastically, it is higher reliability NC lathe that can get consumer favor. Whether the numerical control lathe reliably does become user purchase the important standard. In recent years our country numerical control lathe had the quick development in the production and the application domain, but compared with the developed country there is large distance. 随着社会生产和科学技术的迅速发展，机械产品的性能和质量不断提高，With social production and the rapid scientific and technological development, mechanical properties and product quality improvement. Numerical control technology is one of the key technologies of modern fabrication. In our country, the research level of numerical control technology is very low, which seriously restricts the level of the manufacturing development. So it is a great thing to develop the national numerical control industry. 产品的更新换代也不断加速，因此对机床不仅要求具有较高的精度和生产率，而且应能迅速地适应产品零件的变换。Product upgrading has been accelerated, so the machine not only has higher accuracy and productivity, but should be able to quickly adapt to the change of product components. 生产的需要促使了数控机床的产生，随着电子技术，特别是计算机技术的发展，数控机床迅速的发展起来。Production needs of CNC machine tools to promote the emergence of electronic technology, in particular the development of computer technology, CNC machine tools developed rapidly. ??从第一台数控机床（1952年 美国）问世至今，机床的数控化率在不断的提高。From the first NC Machine (1952 USA) come out so far, the machine tools rate has been raised. 世界各工业国家已普遍生产和应用，日本生产机床的数控化率在1988年就已达到70%。The worlds industrial countries has generally production and application, the Japanese production of the machine tools in 1988, the rate had already reached 70%. 我国从开放搞活以来，加快了数控机床技术的引进，促使我国的机床数控技术的普及和发展。From the opening up of China to enliven, the CNC machine tools to speed up the introduction of technology to promote Chinas CNC technology popularization an
