The surface quality requirements of stainless steel rod deep molds are very high.
A relatively low surface roughness will reduce friction and improve adhesion resistance. After the drawing die is ground, it is more important to eliminate the processing traces.
However, grinding and polishing processes are usually ignored in mold manufacturing.
It should be pointed out that in the entire mold processing process, polishing work takes up one-third, because the appearance quality of stainless steel products depends to a large extent on the mold polishing technology.
The surface roughness of the mold is reduced, and the number of grinding of the mold is correspondingly reduced, and the service life of the mold is correspondingly improved.
For example, the surface of the mold is not polished enough, and the stainless steel sheet is easy to form adhesion tumors when deepened, so the stainless steel products drawn will have very serious scratches.
However, polishing the scratches on the product is time-consuming and ineffective.
Therefore, it is best to increase the function of the mold polishing process. Only the improvement of the mold surface processing accuracy can reduce the scratches of the product, and the mold repair life can be greatly improved.
