一、凸轮磨削振痕的类型 凸轮磨削时如果在整个凸轮表面上产生振痕时,则往往是属于一般的磨削振痕,它的产生原因可能是:机床的旋转零部件例如电机、皮带盘或主轴等的不平衡;主轴轴承等零部件间隙过大;砂轮磨钝、堵塞或不平衡;磨削时砂轮横向进给量过大、工件转速过高;工件刚性 First, the type of cam grinding marks If the cam surface grinding cam generated in the entire surface, it is often a general grinding vibration marks, it may be due to reasons: the rotating parts of the machine such as motors, Belt disc or spindle imbalance; Spindle bearings and other parts of the gap is too large; grinding wheel blunt, clogged or unbalanced; grinding wheel horizontal feed is too large, the workpiece speed is too high; workpiece rigidity
