5、数控机床改造研究为了我国民营企业的生存与发展,提高数控机床的速度是必要的。转型所需的设备一般数控机床,包括传统和最近从国外引进的一个问题,由于不能放入机床设备和生产线。首先,数控机床和生产线改造的主要内容为:(1)恢复原有的功能、机床、生产线有一些故障诊断和恢复;(2),NC-based 一般机床设备或添加加数显著数控系统;(3)改造,提高精度、效率和自动化程度,机械,电气部件的改造、机械部分的维护过程中,才能恢复到最初的辨识精度,不能满足生产要求的数控系统被更新到最新的数控;(4)技术更改或技术创新,以提高性能和品位,或使用新技。

6、数控机床及电气改造,2005.11,数字控制（numericalcontrol）是一种自动控制技术，是用数字化信号对机床运动及其加工过程进行控制的一种方法，简称为数（NC）。IFIP第五技术委员会对数控机床作了如下定义：数控机床是一个装有程序控制系统的机床。该系统能够逻辑地处理具有使用号码，或其他符号编码指令规定的程序。数控系统(程序控制系统)是一种控制系统,能自动阅读输入载体上事先给定的数字值。
