S1302-1-3 Development of Minimized Coolant Supply Technology in Cylindrical Grinding

Abstract

In grinding, airflow generated around the surface of the grinding wheel rotating at high speed, suppresses the grinding fluid (coolant) from reaching the grinding point. To break this airflow, a large amount of coolant has been supplied. In this study, technology has been developed so that coolant will reach the grinding point even with small flow rate, whereby airflow around the grinding wheel surface is intercepted above the grinding point. Grinding test has confirmed that in high wheel speed area, grinding performance equivalent to that of the conventional method can be achieved with half the coolant supply, using the developed technology.
