- 1: The grinding wheels for China metal machining molds should be reasonably selected and trimmed. It is better to select medium grain size in terms of grain size and low hardness in terms of hardness. Therefore, the grinding wheels made of white corundum are better. If the material hardness is relatively high, it is appropriate to select diamond grinding wheel. The grinding wheel should be kept sharp, because once it is passivated, its strength will be reduced and the workpiece will be damaged.
- 2: The cooling and lubricating fluid shall be used reasonably, and its cleanliness shall be maintained to prevent the workpiece from showing thermal deformation. Properly improve the cooling conditions and take some useful measures to better play the cooling role.
- 3: After heat treatment, the quenching stress is reduced to the lowest limit to prevent the workpiece from cracking, so as to improve the toughness.
- 4: Hardware mold making can improve the manufacturing accuracy and surface quality of the mold. Electrolytic grinding can be selected to avoid burrs, cracks and burns, and improve the surface roughness of the mold.
- 5: The grinding amount for hardware mold manufacturing shall be selected reasonably, the contact area between the grinding wheel and the workpiece shall be reduced, the heat dissipation condition shall be improved, and then the temperature can be controlled well.
