■80A wheel
80A abrasive is a monocrystalline alumina abrasive, manufactured by the advanced technique.
Due to the extreme hardness and unique fracturing which generates many new cutting edges,
it has longer wheel life and lower grinding force than that of WA.
It also gives better cost performance than a ceramic abrasive wheel at low metal removal rate of 3mm3/mm・sec.

■Selection of the bond type for 80A abrasive:
　 □V201 is the standard vitrified bond.
　 □V208 is designated for hard grade
　 □V201R, and V208 are designated for semi-porous wheel.
　 □V201P is designated for porous wheel.
　 □V203 is designated for high-porous wheel.

■85A wheel
85A abrasive is developed for higher grinding performance than that of a conventional pink colored alundum abrasive.
