1、摘 要数控机床以它生产效率高、可加工零件多样化的特点,越来越显示出它的优越性,然而,很多资深的老企业还存在着许多原有的普通机床,如何将普通机床改造成数控机床,已成为机械加工设备改造工作的重点。本文以CA6140普通车床为例阐述了对普通机床进行技术改造的必要性,提出了该机床数控化改造的方案并实施了改造。机械部分改造主要做了以下工作:将两个进给方向的滑动丝杠改为滚珠丝杠,用伺服步进电机和减速齿轮来实现进给部分的调速,这样不仅提高了传动效率而且可以实现快速定位和准确的启、停;数字控制系统选用广州数控设备有。关键词:数控机床;数控化改造;数控系统AbstractBased on its high pr
2、oduction efficiency, machinable parts diversification, CNC machine has increasingly shown its superiority. However, many senior enterprises still have large amount of original general-purpose machine tools, how to transform the ordinary tools into CNC machine tools has became the focus of the mechan
3、ical processing equipment modification. Based on CA6140 centre lathe, this paper expounds the necessity of the technological transformation to general-purpose machine tools, and purposed transformation of the CNC program and implemented a transformation. Mechanical parts reconstruction made the foll
4、owing job: taking the two feeding direction of sliding screw instead of ball screw, servo stepping motor and reduction gear to realize the speed regulation of the feed part, this works not only improve the transmission efficiency ,but also achieve rapid positioning and accurate start , stop.
