|Title||High Quality Grinding Disc Related Knowledge|
|Description||I have introduced high quality grinding disc many times before. High-precision optical components, such as photographic objectives, prisms, and filters, are polished or refined for polishing. After polishing, polishing powder such as asphalt or polyurethane, polishing powder such as zirconia is used. The polishing process is to remove the altered layer produced in the previous process and obtain an optical surface with no defects in appearance and surface accuracy. At present, high quality grinding discs are gradually replacing traditional grinding methods with fixed abrasive grinding methods, and polishing processes have begun to test fixed abrasives.|
