Abstract

The authors propose a new coolant named"micro bubble coolant" which includes micro bubbles (20 - 50μm in diameter). In a previous study, it was clarified that tool life was improved by applying this new coolant to various types machining applications, such as boring, turning, and grinding. This paper deals with the purification effects of the micro bubble coolant. Experiments indicated that bacteria that cause putrefaction of conventional water soluble coolant are eliminated by generating micro bubbles in the coolant. It was also demonstrated that the micro bubble coolant isolates minute machined chips and machine oil from the coolant.
