6.2 Grinding Wheel Speed Chart
The grinding wheel speed chart shown below should be used as a guide to the permissible wheel
surface speeds (in m/s) for the given diameter of wheel.
Ensure that the grinding wheel operates within the “Work Zone” area as shown in the chart above.
CAUTION
The programmed speed (RPM) of the grinding spindle must NEVER exceed the
maximum rated speed marked on the grinding wheel.
Using the expression below you can calculate the grinding wheel surface speed (M/s) for a given
wheel diameter at a given rotational spindle speed (rpm):
