GRINDING FEEDS AND SPEEDS

An excerpt from Abrasives Methods by Francis Farago, 1976 out of print. Grinding wheel speeds should be maintalned with-in a range of 5000 to 6500 feet per minute (1525 to 1980 meters per mm), unless special conditions prevall or equipment and wheels designed for substantially higher wheel speeds are used.

SFPM vs. RPM - practicalmachinist

SFPM vs. RPM. That's going to depend on your abrasive material and your grinding process. It could be anywhere from 4,000 to 12,000 SFPM, which means you either need to ask an old hand, consult your wheel maker's application engineers for advice, or do some experimentation to see what works best for your particular situation.

Grinding Wheel Safety: Respect The Maximum Speed

This less severe over-speed condition can cause the wheel to be damaged, and the damage may result in breakage after further use. For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack.
