三菱M70数控系统主轴外置接近开关定向功能

The spindle orientation function of MITSUBISHI M70 CNC with external approach switch

对于加工中心机床,当主轴电动机和主轴非1:1连接时,要实现定向功能,需要在主轴侧增加闭环检测装置,一般采用1024脉冲的旋转编码器。但是,对于某些结构特殊的加工中心机床,其主轴侧没有足够空间安装编码器,只能采用体积更小的检测器件,例如接近开关等。介绍三菱M70数控系统使用主轴外置接近开关时如何实现定向功能。

For processing center machine,when it is not connected with 1：1 between spindle motor and spindle,it should add close-loop testing device at the side of spindle for the orientation function.Normally,a rotary encoder with 1024 pulses can be used.But,for some special machines,there is not enough space to fix the rotary encoder,and only can use a little testing device,for example,approach switch,etc.The article introduces that how to realize the spindle orientation function of MITSUBISHI M70 CNC with external approach switch.
