一种加工中心机床主传动自动变速系统

A Kind of Automatic Change Speed System of Main Shaft Transmission for Machining Center

加工中心主轴传动系统是传递切削功率的重要部分,介绍了采用PLC技术控制实现了主轴按程序要求自动机械变速的方法。即能保证主轴有较宽的调速范围,又保证了低速重切削的工艺要求。可供数控机床的设计研究人员和运行维修技术工作者参考。

Main shaft transmission system of the machining center is the important part to transmit cutting power.This paper describes the main shaft change speed adopting PLC control as required automatic procedure.This gives main-shaft larger transferring speed range and guarantees technological low-speed cut.It recommends numerical control lathe designers and operators ＆ servicemen to study.
