1、当前世界NC机床的研究现状
世界各国对数控机床、加工中心以至FMS、CIMS等各种新技术的研究与发展进程，是与世界经济形势紧密相连的。机床工业有世界经济相互促进和发展，进入21世界知识机警时代，人们的知识所起的作用更加突出，而机床工业作为机器制造业的基础，其重点地位与战略意义也更加明显。在1991—1994年间，世界经济衰退，昂贵的FMS，CIMS降温，1995—2000年间，世界经济在低速增长，根据当前世界市场各方面用户为提高生产率对NC机床的要求以及世界四大国际机床展（欧洲的EMO、美国的IMTS、日本的JIMTOF、中国的CIMT）上展品的分析，当前世界NC机床的技术研究主要有以下几点：
（1）、更加重视新技术和创新
在世界范围内，对新工艺、新材料、新结构、新单元、新元件的研究开发工作正在大力开展，如新的刀具材料、新的主轴结构、高速电主轴、高速直线电机等的开发研究。以加工工艺的改进创新为基础，为加工超硬、难切削材料及特殊复合材料及复杂零件、不规则曲面等在不断研究开发新机种。

1、Research current situation of NC lathe in our times [来源：http://www.doc163.com]
Research and development process to such various kinds of new technologies as numerical control lathe , machining center , FMS , CIMS ,etc. of countries all over the world, linked to with the international economic situation closely. The machine tool industry has international economy to mutually promote and develop, enter 21 alert eras of World Affairs, the function that people's knowledge plays is more outstanding , and the machine tool industry is regarded as the foundation of the manufacturing industry of the machine, its key position and strategic meaning are more obvious. Within 1991-1994 years, the economic recession of the world, expensive FMS, CIMS lowers the temperature, among 1995-2000 years, the international economy increases at a low speed, according to requisition for NC lathe and the world four major international lathes exhibition in order to boost productivity of users of various fields of present world market (EMO , IMTS , JIMTOF , China CIMT of Japan of U.S.A. of Europe), have the analysis of the exhibit, there are the following several points mainly in the technical research of NC lathe in our times: [来源：http://Doc163.com]
（1）、Pay more attention to new technology and innovation
