Ceramic abrasives grain( SG material)

Ceramic abrasives grain , blue colour. SG material,

1) Billions of crystals

2) Self-sharpening grain provides more aggressive cut for a longer period

3) Best grain for high stock removal especially under lighter presures

Compare to AO ,SIC AND Zirconia Alumina

A/O & SIC

1) single crystal

2) cut rate decays at start of grinding

3) Good general purpose grains

Zirconia Alumina

1) Thousands of crystals

2) Self-sharpening decays during grinding

3) Better grain for abusive removal applications
