Grinding disc for optical lenses, fine stones, marble, wood, metal, plastics etc.

摘要

The grinding disc has a base body (3), formed of carbon fibre tissue or weave or a graphite film, with a diamond or boron nitride coating (1) as a grinding layer. The diamond or boron nitride coating can be attached to the base body by gas phase deposition. The diamond or boron nitride coating can have a thickness or five to fifty microns. Between the base body and the coating, there can be an intermediate layer (2) or pure metal ie. gold, silver, platinum or iridium. The intermediate layer can be electrolytically coated onto the base layer.
