Centerless and Cylindrical Grinding aztecplastic

The concept is relatively simple. The workpiece is fed between two wheels rotating at different speeds. The grinding wheel rotates at a speed that applies a downward force to the workpiece and grinds the workpiece while holding it in place. The regulating wheel (or moving wheel) applies lateral force to the workpiece and controls the rotational speed.

When the abrasive is applied to the workpiece, rotational speed decreases as the abrasive is held back by the torque caused by grinding action and feed force. A great deal of the energy is lost through heat. The more feed force the operator applies to the tool, the lower the rotational speed. For the simplest type of non-governed air tool, rotational
