摘要
企业要想在现在市场中得到稳定的发展,想要很好的生存下来,就必须保证以高质量低成本的理念来创造出适合市场需要的,性能合适的产品。而产品品质的好坏,生产成本的高低,生产周期的长短,又极大的会受到现有加工条件的制约。从长远来看,先进数控机床的普及,已经成为我国制造业兴起不可或缺的重要元素。先进数控机床的进口能提高我国数字控制的拥有率,但其耗资大。所以,数控机床的革新也就成为了提高机床数控性能的有效途径。从而减少成本,提高生产量的产出率。数控机床因加工精度高,适应不同加工条件及需求等方面的长处,越来越能显示出它在制造产业中的地位。因而,如何将一般机床革新成为数控机床成为了我国未来制造业发展的重要课题。

Abstract
Enterprises to obtain the stable development in the market now, want to good to survive, you must guarantee to the philosophy of high quality low cost to create suitable for the market need, performance suitable products. And the quality of the product, the production cost, the length of the production cycle, and greatly will be restricted by the existing processing conditions. In the long run, the popularization of C machine tools has e an indispensable element in China's manufacturing industry. The import of C machine tools can improve the rate of control of digital control in China, but it is expensive. Therefore, the innovation of nc
machine tool has e an effective way to improve the nc performance of machine tools. To reduce the cost and increase the output rate of production. Numerical control machine tool is more and more able to show its position in the manufacturing industry because of its high machining accuracy and the advantages of different processing conditions and requirements. Therefore, how to turn the general machine tool innovation C machine tool es an important issue in the future manufacturing development of China.
Keywords: numerical control transformation; Mechanical processing; Ordinary machine tools;
