Speed calculator

Calculate the peripheral speed, the optimal spindle speed, or the grinding wheel diameter:

Calculate grinding wheel peripheral speed (v)
Peripheral speed is the speed at the wheel’s rim (usually expressed in m/s). Grinding wheels have permissible maximum peripheral speeds—also called maximum operating speeds—that must not be exceeded. Always follow the manufacturer’s specifications and safety instructions.

Units: m/s (or m/min)
