Minimization of Grinding Fluid by Employing the Supplying System from Inner Side of Grinding Wheel and its Effect

Grinding fluid is generally supplied from the supplying nozzle to the grinding point. However, if the amount of the grinding fluid is decreased, it is difficult to reach the grinding wheel because the air layers which rotate with periphery of grinding wheel rotating in high speed. Therefore, the system which can supply the grinding cutting fluid through the grinding wheel was developed and evaluated. Grinding force and grinding surface temperature were measured by applying the developed supplying system with varying the amount of the coolant supply. As a result, it was clarified that smaller amount of the coolant supply can keep the cooling and lubricating effect comparing with the conventional coolant supply.
