How to improve the shape preservation of the grinding wheel?

Some customers encounter poor shape preservation of the grinding wheel in the grinding process, the shape preservation of the grinding wheel refers to the performance of the grinding wheel to maintain the original shape in a certain period of time, so how to improve the shape preservation of the grinding wheel? We usually solve this problem by adjusting the hardness of the bond. However, after the hardness of the bond is increased, there may be another problem, if the grinding wheel is too hard, it will cause grinding immobility. Therefore, for the shape preservation of the grinding wheel, we have the following two plans.

Plan1: suitable abrasive by adjusting the hardness of the bond, it can smoothly solve the shape preservation of the grinding wheel.

Plan 2: By adjusting the hardness of the bond, no matter how to adjust, the problem is that the grinding wheel has poor shape preservation and grinding immovable situation, then at this time, we need to consider replacing the abrasive, if you used white corundum before, we can try to change the SG grinding wheel, if SG can't work, we can consider super-hard grinding wheel, that is, CBN grinding wheel. Of course, if you use silicon carbide, you must use diamond grinding wheels as an alternative.

Therefore, it is mainly the hardness of the grinding wheel that affects the shape preservation of the grinding wheel. The hardness of the grinding wheel can be improved by adjusting the quality or type of the bond, and the hardness of the grinding wheel can also be affected by adjusting the temperature during the sintering process. Secondly, the hardness and grinding characteristics of the abrasive itself should also be used as another factor that can achieve grinding performance on the basis of maintaining the shape of the grinding wheel.
