How to Calculate Wheel Speed | Sciencing

Calculate the circumference of the wheel. Use the formula: c = 2_pi_r, where c is the circumference, r is the radius, and pi can be approximated by 3.14. Following the example, if the car wheel has a radius of 0.3 meters, then the circumference is equal to: 0.3 x 3.14 x 2 = 1.89 meters. Calculate the wheel speed in revolutions per minute.

Grinding Wheel Safety: Respect The Maximum Speed

In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine’s speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.
