Abstract

In order to investigate the effect of ultrafine bubbles in a coolant, the authors developed the antifoaming techniques which eliminate the gaseous bubbles from the coolant with a mixture of gaseous and oil bubbles. The effect of gaseous bubble in a coolant is evaluated by both the grinding force and the surface temperature of a workpiece during the surface grinding. Finally, the cooling efficiency of a coolant with gaseous bubbles is evaluated.
