Effect of Hardness on Polishing Performance of Plastic

In this paper, the comparisons of the polishing performance between prehardened P20 and S45C steels under the different hardness were carried out by using surface grinding, manual polishing and PVA grinding wheel polishing tests. The results show that the surface roughness of the two kind steels decrease with the increase of hardness and the roughness of S45C is lower than that of P20 during Fundamental study of ultrasonic polishing of mold steel As polishing of steel mold has been a serious concern in the industry, an innovative cost-effective ultrasonic polishing system is developed for this purpose. The ultrasonic tool moves in a patterned path to cover the entire surface to be polished. Microcutting, plowing and indentation by abrasives are observed on the polished surface.
