... metallurgical damage, higher wheel speeds in the range of 45 to 63 m/s (9000 to 12,500 sfm) are often used. In precision grinding, the power required to run at higher speeds tends to make burn-free grinding more difficult, and minimizing metallurgical damage is more important; therefore, speeds of 25 to 43 m/s...
