3MZ1420轴承外沟道磨床改造

Improvement on 3MZ1420 bearing outer raceway grinder

针对3MZ1420轴承外沟道缺少反磁环节,线路老化,维修困难,缺少计数修整,不方便操作者选择修整方式等问题,增加反磁电容,并利用PLC对原有设备进行改造,增加计数修整程序,使得操作简单,维修便捷,解决了套圈的残磁问题,增加了电气元件的使用寿命,减少了机床维修时间。

In view of these phenomena with 3MZ1420 bearing outer raceway： lack of anti-magnetic process, aging lines, difficult in maintenance, lack of counting dressing, and inconvenient for operator to select dressing methods, anti-magnetic capacitance was added, and the original equipment was improved using PLC. By using the counting dressing program, the equipment bacame simple in operation and convenient in maintenance, and the problem of residual magnetism of ring was solved and the service life of the electrical elements was increased with less machine maintenance time.
