Grinding wheel raw material SG ceramic abrasives

Description for SG ceramic abrasives:

SG ceramic abrasive is a kind of sintered abrasive made by sol-gel method with special alumina as the main raw material and a variety of modified components. SG ceramic abrasives can be applied to both consolidated and coated abrasives. SG ceramic abrasives has a wide range of applications, both for casting grinding under high pressure conditions, and for fine grinding of a variety of materials, including gear grinding bearing grinding, crankshaft grinding, roll grinding and others.
