文档介绍：CA6140普通车床的数控化改造
摘要
针对大多数企业,具有数量众多和较长使用寿命的普通机床,其加工精度较低、不能批量生产,自动化程度不高,自适应性差,但考虑投资成本,产业的连续性,又不能马上被淘汰。
数控机床作为机电液气一体化的典型产品,能解决机械制造中结构复杂、精密、批量、零件多变的问题,加工质量稳定,生产效率较高。
购买新的数控机床是提高产品质量和效率的重要途径,但是成本高,许多企业在短时间内无法实现,这严重阻碍企业设备更新的步伐。为此把普通机床数控化改造,不失为一条投资少、提升产品质量及生产效率的捷径,提升企业竞争力,在我之地。

ABSTRACT
Most enterprises still have large amounts general-purpose machine tools which have longevity of service, low precision, can not adapt to mass production, low automatization and adaptability, but can not be washed out because of its low cost and continuity of enterprise’s production.
As a representative production of mechanical, electronic, hydraulic and pneumatic integration, numerically controlled machines have a stabilization quality and high efficiency, and can solve problems such plex structure, high precision, mass production, part variety in machining.
Purchasing new numerically controlled machines is an important way to improve production precision and efficiency, but it may e true to many enterprises because it cost much. Enterprises’ equipment updating step are counteracted severly. So General lathe's numerically controlled reforming is a quick way that costs less, improve production precision and efficiency,
and it can improve enterprises’ competitive power. So it can takes its place in our way to a powerful manufacturing country.
Key Words: General purpose lathe, Numerical control(NC),Reform
