Ceramic Alumina Abrasive, generally called “SG” is a newly developed alumina abrasive. Different from fused alumina, it is made from chemical and sintering process. It mainly shows white or blue color, and has sharp or blocky natural shape. Also grains with different precise shape such as rod/prism/triangular have been developed for different applications.
Ceramic alumina abrasive in the grinding process, the fracture mechanism is different from fused alumina. The core theory is continuous to create new nano level sharp blade for cutting, then the ceramic alumina abrasive can have more efficiency and more durability.
For the nano level crack feature, ceramic abrasive is fit for hard material grinding, such as aerospace alloy, hard tool steel and hard forged steel etc. And ceramic alumina abrasive can be made to different kind of grinding tool, such as bonded wheel, depress wheel, coated abrasive etc. Usually it is mixed with other grains for better cost and different applications.
Ceramic alumina abrasives are mainly used for below applications:
Also ceramic alumina abrasives could be used for a number of other grinding applications. The manufacturer need consider the difference of each kind of ceramic alumina abrasives to balance the toughness and sharpness. And specialized bonding system is much needed for ceramic alumina abrasive tool manufacturing.
