The selection of abrasives should be based on the mold material to choose the appropriate hardness and particle size, to avoid hard or too fine abrasives to cause damage to the mold.

When grinding, apply uniform force, do not exert too much force, so as not to cause uneven mold surface.

The grinding direction should be perpendicular to the surface of the die to avoid grinding marks during the grinding process.

During the grinding process, it is necessary to ensure that the mold surface temperature is consistent to avoid unnecessary damage caused by local overheating or undercooling.

After grinding, the surface of the mold should be cleaned to ensure that the surface is smooth and without wear marks.

In addition, it is also necessary to understand the characteristics of the mold material and its requirements for the wear resistance and hardness of abrasives and abrasives, and to ensure that the operator has sufficient grinding skills and safety awareness.
