在机械制造业中经常加工轴套类零件,并且对端面与中心的垂直精度有一定要求。因为轴套端面与中心的垂直度往往影响部件的定位和同心度。因此,根据轴套的精度选择相应精度的心轴,是磨削高精度轴套的重要环节。像速率台密珠轴系中的轴套(如图1), In the machinery manufacturing industry often processing sleeve parts, and the vertical accuracy of the end face and center have certain requirements. Because the hub perpendicular to the end face and the center will often affect the positioning and concentricity. Therefore, according to the accuracy of the sleeve to select the appropriate precision mandrel, grinding high precision sleeve an important part. Like speed Taiwan dense shaft sleeve shaft (Figure 1),
