How to polish the punch head

Head application field is wide, changhui head factory how to punch head polishing, the following for the new and old users to introduce a few methods:

 1, rough casting is with a hard wheel to punch head surface grinding, polishing or grinding, so rough casting is also known as grinding or grinding. It is mainly used to remove burr, scratch, rust, oxide, sand hole, bubble, welding tumor, welding slag and a variety of macro defects on the surface of parts, in order to improve the surface flatness and reduce the surface roughness.

2. Medium casting is further processing of rough casting surface with a hard polishing wheel pair, which can remove scratches left by rough casting and produce a smooth to medium bright surface. The surface roughness ranges from a few tenths of a micron to a few microns.
3. Fine casting is the last working procedure of punching head polishing, which is a method of machining parts' surface with soft wheels coated with polishing paste. Since it is carried out on the already smooth surface, the roughness of the surface can be further reduced to achieve the purpose of micro-leveling, so that a very bright surface can be obtained. Moreover, there is no obvious abrasion on the base material during the head polishing, and the surface roughness can reach about 0.01 nm, which can truly achieve the mirror brightness.
