Abrasive Wheel Grit Size Superabrasive Wheel Grit Size Feed depth per pass (Roughing)(mm) Feed depth per pass (Finishing)(mm)
C 501 426~126 0.10~0.02 0.03~.02
C 251 151~76 0.05~0.02 0.02~0.01

Note  

1. C means Green SiC grinding wheel, A means White corundum grinding wheel.
2. Both C and A abrasive wheels hardness code shall be J or L.
3. The abrasive wheel RPM shall be higher than superabrasive wheel RPM. The recommend RPM of abrasive wheel shall be 4-6 times of the superabrasive wheel RPM.
4. Normally, the abrasive wheel diameter shall be bigger than superabrasive wheel diameter.
PS: Do not use small diameter and low RPM abrasive wheel to dress large diameter and high RPM superabrasive wheel.
