The ceramic abrasive is made of special alumina as the main material, mixed with a variety of rare earth modified components, and is sintered at high temperature. It has high hardness and self-sharpening. Yousheng relies on the unique concept of grinding and adds special chemical to make ceramic abrasive with characteristics of cold cutting. The ceramic abrasive can maintain a longer-lasting grinding force, so that the made abrasive tools can reach an ultra-long life. The abrasive has a very wide application range, which can be used for casting and grinding under high pressure, and for fine grinding of various materials, including gear grinding, bearing grinding, crankshaft grinding and others.
