中文摘要
随着装备制造业和机械加工业的发展,数控机床的需求量愈来愈高,经济型数控机床仍然是我国市场需求量最大的数控机床。机床数控化改造是继我国引进、吸引国外数控机床技术之后开始发展的。利用现有闲置的旧机床,通过数控化改造,使其成为一台新高效、多功能的数控机床,是一种盘活存量资产的有效方法,也是低成本实现自动化的有效方法。近两年随着我国数控系统技术的不断发展,数控机床的生产量不断增加。从我国目前机床设备生产的现状来看,仍然以生产普通机床为主,所以机床设备的数控化改造将会长期存在,据有关统计资料表明,每年大约有10万台机床需要改造,维修改造的市场前景十分广阔。

Abstract
With the development of equipment manufacture and mechanical processing industry, numerical control demand of lathe higher and higher, economy numerical control lathe remain of our country market demand loud numerical control lathe most. The lathe numerical control transformation begins development after introducing, attracting the foreign numerical control lathe technology in our country. Utilize existing old lathe that leave unused , through numerical control transformation , make it e one new high-efficient , multi-functional numerical control lathe, it is an effective method to liquidize remnant assets, it is the low cost that realizes the automatic effective method too. With the constant development of the systematic technology of numerical control of our country, the amount of production of the numerical control lathe is increasing constantly in the past two years. According to current situation of device fabrication of the lathe at present of our country , still mainly product ordinary lathe , so the numerical control transformation of the machine tool will exist for a long time , indicate according to relevant statistical data, probably 100,000 lathes need transforming every year, it is very broad to maintain the market prospects transformed.
Key word: Economy Numerical control Long-term Market prospects
