I have previously introduced diamond high quality grinding disc with many times. High-precision optical parts such as photographic objective lenses, prisms and filters are polished after classical fine grinding or diamond refining. After polishing, the polishing molds made of asphalt, polyurethane polishing dies and the like are used. , zirconia and other polishing powder. The polishing process is to remove the altered layer produced during the previous process, and obtain an optical surface having no defects in appearance and surface accuracy. Currently. The fixed abrasive grinding method using diamond refining sheets is gradually replacing the classical grinding, and the polishing process has begun to test the fixed abrasive.
