东德的机械制造工业广泛采用一种简单而又十分有效的新抛光法,简称 MHK。它使用了嵌有研磨颗粒(主要是碳化硅)的硅橡胶。因为硅橡胶与研磨颗粒之间具有低的附着力,所以在使用过程中,研磨颗粒可以转动。从而露出新的锐利的棱边。制造这些抛光工具的技术有两种:冷凝固硅橡胶和热凝固硅橡胶。但基本的步骤是通过搅动或捏合,使研磨颗粒、硅橡胶和润湿剂混合,然后压入或铸入横子内。这种简单的 East Germany’s machinery manufacturing industry widely used a simple and very effective new polishing method, referred to MHK. It uses silicone rubber embedded with abrasive particles (mainly silicon carbide). Because of the low adhesion between the silicone rubber and the abrasive particles, the abrasive particles can rotate during use. Exposing new sharp edges. There are two technologies for making these polishing tools: cold-setting silicone rubber and thermally-setting silicone rubber. However, the basic procedure is to mix the abrasive particles, the silicone rubber and the wetting agent by agitation or kneading, and then press-fit or cast into the transverse yoke. This simple
