Super Hard Abrasive--Diamond

MORESUPERHARD is a professional manufacturer that processes the world's hardest material-diamond into tools. Products (mainly used for drilling, grinding, polishing, cutting, etc.) are used in many fields such as automobiles, electronics, semiconductors, conveying machinery, machinery, bearings, knives, molds, glass, ceramics, civil engineering, mining, stone, construction, etc. Is widely used. We produce comprehensive professional tools for most diamond and CBN (boron nitride) products, such as grinding wheels, dressers, blades, band saw blades,drills, etc.



Diamond is the hardest material on the earth today. Alumina has the longest history in the grinding industry. Its good dressability can greatly increase its life and productivity by one hundred times that of alumina abrasives.
