我厂有一台ZSKW花键磨床,是用油压分齿的。在正常情况下,磨完一个键槽,工作台就自动返回,砂轮从刚磨完的键槽退出。机床的分齿机构带动工件自动地转动一个键,砂轮再进入这一待加工的键槽,进行磨削。如果分齿失灵,工件转动不够一个键,或大于一个键,机床工作台就会因为 I have a factory ZSKW spline grinding machine, is the use of hydraulic sub-tooth. Under normal circumstances, grinding a keyway, the table will automatically return, the wheel from the just finished keyway exit. The tooth-dividing mechanism of the machine tool drives the workpiece to automatically rotate a key, and the grinding wheel then enters the keyway to be processed for grinding. If the sub-tooth failure, the workpiece rotation is not enough a key, or more than one key, the machine table will be because
