Grinding wheel speeds are generally given in SFPM while machine speeds are usually noted in RPM. Since these numbers are measured at different locations on the grinding wheel, you must know how to convert one to the other. The basic equation is: SFPM = Wheel Diameter in inches x RPM x 0.262. Why is this important?
