Development of Minimized Coolant Supply Technology in Grinding (ECOLOG Grinding TYPE II)

摘要

In grinding, a large amount of grinding fluid (coolant) is supplied in order to break the air flow circulating with the rotating grinding wheel and reach the grinding point. In this study, technology to reduce the required amount of coolant supply has been developed whereby air supplied above the grinding point from the side of the wheel effectively intercepts the air flow around the wheel. Evaluation testing has confirmed that in high-efficiency grinding, grinding performance equivalent to that of the conventional method can be achieved with half the coolant supply. In addition, wheel spindle power loss due to coolant has been reduced by around 50%. In the case of grinding where the grinding point moves up and down over a wide area, it has been confirmed that coolant reaches to the lower part of the wheel, unlike conventional methods.
