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 …
A grinding head unit is constituted by a grinding wheel, a drive device for rotating the grinding wheel, and a movement device for moving the grinding wheel. When vibration of a mill roll is applied to the grinding wheel, a plain wheel integral with an abrasive layer of the grinding wheel and having an elastically deforming function is deflected to absorb the vibration energy.
