The speed of a grinding wheel is expressed in surface feet per minute (fpm) or, in the metric system, meters per minute (m/min). It is easiest to think of surface speeds as the distance a given point on the outside of the wheel will travel in a minute. Most vitrified wheels operate at about 6500 fpm (1980 m/min), or a little over 60 mph (97 km/h). ................
