Jingu M-bond diamond grinding & polishing block, with a supply grit sizes of 46#-400 #, can replace the ordinary silicon carbide grinding block, and is used for the fine grinding and polishing of ceramic polishing tiles. It is sharp, wear-resistant, shock absorption and noise reduction, which greatly improves the consistency of transparency and luminosity after polishing the ceramic surface, reduces the processing cost of the ceramic factory and the labor intensity of the workers, reduces the quantity of waste recovery. The service life is more than 120 times of ordinary silicon carbide ones.
