Research on improvement of environment of cutting and grinding processing by micro bubble

水溶性冷却剂是易腐烂的，因为90%或更多是组成水。本研究提出了一种利用微气泡净化水溶性冷却剂的新方法。实验阐明了微气泡对冷却液中细菌的灭活作用和悬浮物的分离作用。将浮动喷嘴等减少冷却剂的方法与微气泡相结合，构建了具有环保意识的冷却剂系统。此外，还发现在冷却剂中加入负离子以产生微气泡，从而控制了冷却剂的臭味。

Water soluble coolant is perishable, because 90% or more is composed water. In this study, an original purification method using micro bubbles for the water soluble coolant was proposed. It was clarified experimentally that the actions of the inactivation of bacteria and the separation actions of suspended substances in the coolant by the micro bubbles. An environment-conscious coolant system was constructed with the combination of the method of decreasing coolant like a floating nozzle and the micro bubble. In addition, it was found that mixing a negative ion into the putrefied coolant for the micro bubbles controlled a bad odor of the coolant.
