No @Amitraghat.

Option c is right. Because each particular type of grinding have some particular speeds depending on the type of operations.

SFPM only for grinding or other process?

Surface Feet Per Minute (SFPM).
Sanjay said:   7 years ago
SFM means?
Amitraghat said:   8 years ago
It is option D.
Saurav said:   8 years ago
SFM = RPM x DIAMETER x 0.262.
m/min = 3.142 x DIAMETER x RPM dived by 1000.
