摘　　要：介绍了大型轴承双端面磨床差速磨削的电气改造方案,通过对硬件线路的简单改变,改造后的机床使用方便,可靠地实现变频调速运行与Y/△运行的相互转换,降低了故障停机时间。The electric reform plan of double side surface grinder for eifferential grinding of the large size bearings is introduced. By simple improvement of hardwire circuits, mutual switch between frequency conversion timing operation and Y/△ operation in the machine is conveniently and reliably realized, the failure time is reduced.
