  • How to solve common problems in polishing (2)

    1) Causes of "pitting" on the surface of the workpiece Because there are some non-metallic impurities in the steel, which are usually hard and brittle oxides, they are pulled out from the surface of the steel during the polishing process to form pitting corrosion. The main factors that produce "pitting…

  • How to solve common problems in polishing (1)

    1) Over polishing The biggest problem encountered in the daily polishing process is "over-polishing", which means that the longer the polishing time, the worse the quality of the mold surface. There are two phenomena of over-polishing: "orange peel" and "pitting". Excessive polishing occurs mostly in mechanical polishing. 2) Reasons for…
