Working principle of Grinding Machine The working principle of a grinding machine is quite easier to understand. In a grinding machine there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley. So when we start the electric motor the motor rotates at a certain rpm 150 15000 RPM it may change according to the types of grinding
