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 machine) with the help of v-belt and cone pulley the grinding wheel also starts rotating and we perform the operation.
When the roller is rotating, there is friction between the plate and the roll, so when the roll is rotated, the plate also moves along its longitudinal direction. Lower roller under positive &negative rotation alternately and rolled plate move back and forth, two lower roller rotation and the friction drive plate and roller …
