In the process of industrial products' diversification and high-grade development, it is an important task to improve the quality of mould which directly affects the quality of products. In the process of mold manufacture (mold maker china), the smooth processing and mirror machining after shape processing are called parts surface grinding and polishing. It is an important process to improve the quality of the die. Reasonable polishing method can improve the quality and service life of the die, and then improve the quality of the product. 

As mechanical polishing is mainly done by hand, polishing technology is still the main reason affecting the quality of polishing. In addition, it also relates to the mould (mold maker manufacturing china) material, the surface condition before the polishing and the heat treatment process. High quality steel is a prerequisite for good polishing quality. If the surface hardness of the steel is uneven or different in quality, it will often cause polishing difficulties. All kinds of inclusions and pores in the steel are not conducive to polishing. 

Hardness increases the difficulty of grinding, but reduces the roughness after polishing. As the hardness increases, the polishing time required to reach a lower roughness increases accordingly. At the same time, the higher the hardness, the more likely the polishing will be. When the steel is broken in the machining process, the surface of the mold (supreme machined parts) will be damaged by heat, internal stress or other factors. Improper cutting parameters will affect the polishing effect.
