The centerless grinder is mainly composed of three mechanisms: grinding wheel, adjusting wheel and workpiece support. The grinding wheel actually performs the grinding work. The adjusting wheel controls the rotation of the workpiece and controls the feed speed of the workpiece. As for the workpiece support, it is grinding To support the workpiece during cutting, these three parts can have several matching methods, except for stopping grinding, which are all the same in principle.
Let me share the taper error of the centerless grinder.
1. The front guide plate is inclined in the direction of the guide wheel, causing the front diameter of the workpiece to be too small, or the rear guide plate is tilted in the direction of the guide wheel to cause the rear diameter of the workpiece to be too small. Adjust the front and rear guide plates so that they are parallel to the generatrix of the guide wheel and on the same straight line.
2. The dressing of the grinding wheel is inaccurate, and it has a taper. According to the direction of the taper of the workpiece, adjust the angle of the dresser of the grinding wheel and rework the grinding wheel.
3. When the axis of the workpiece is not parallel to the axis of the grinding wheel and the guide wheel, adjust the height of the pallet before and after or trim the pallet.
4. When the surface of the grinding wheel and the guide wheel is worn, the grinding wheel and the guide wheel need to be re-dressed.
