The self-sharpening effect of the grinding wheel in grinding can correct the shape of the grinding wheel, improve the processing quality, and keep the grinding wheel in good grinding performance.
The self-sharpening effect of the grinding wheel is an important physical phenomenon. It manifests itself in the grinding process as the sharp abrasive grains on the grinding wheel are gradually blunted. Due to the increase in the force, when the strength of the abrasive is exceeded, the abrasive grains are broken to form a new grinding edge; when this force exceeds the bonding strength of the binder, the abrasive falls off the grinding wheel by itself, exposing new abrasive grains. The ability of this abrasive to break itself to produce new corners and to fall off in time to expose new abrasive grains enables the grinding wheel to maintain its sharpness, thereby maintaining good grinding performance during the grinding process. The self-sharpening effect not only helps to correct the distortion of the grinding wheel shape, but also improves the surface quality of the parts and ensures the processing quality. In addition, the self-sharpening effect timely updates the grinding edge of the grinding wheel through the self-breaking and falling off of the abrasive grains on the grinding wheel, avoids the reduction of the hardness of the grinding wheel, and ensures that the grinding wheel can still maintain a good grinding effect after long-term use.
