At this time, the grinder should be adjusted or repaired.
During the batch grinding, if the taper holes appeared in midway, at this time, do not blindly adjust the grinder,because the grinding wheel dull or grinding block, can all cause the wall thickness of the work piece hole’s difference become too large, and the difference of thermal expansion also results in to the taper hole.
