How to adjust the length of grinding area and how to operate it

1. Theoretically, the grinding area needs to reach about 80% of the width of the grinding wheel, and the workpieces with different lengths will be slightly different. Generally, the workpiece size obtained by the common method of centerless grinder is about 1.5 times the width of grinding wheel. Of course, this data is not fixed, but an approximate value, which is not applicable to all workpieces.

2. If the grinding area is less than 80%, it has little influence on the size of long and short workpieces, but it will affect the machining efficiency. Because the grinding area is too short, the position of grinding wheel wear is concentrated in one point, and excessive wear of grinding wheel will change the grinding angle and produce defects. If about 80% sand particles from the grinding area to the surface of the grinding wheel can cut the workpiece evenly without serious local wear, the machining efficiency will be improved and the dressing times of the grinding wheel will be reduced. The requirements for the external diameter of products are not high, and efficiency should be rushed.
