Proc. ASME. LEMP2020, JSME 2020 Conference on Leading Edge Manufacturing/Materials and Processing, V001T03A005, September 3, 2020
Paper No: LEMP2020-8532
... efficiency improvement of hardened steel has not been achieved because the tool life is reduced due to significant progress in tool wear and the occurrence of tool chipping. Therefore, a machining efficiency improvement is desired. In previous research, a machining efficiency improvement of 3 to 5 times can...

... which micro bubbles (20~50µm in diameter) are included in water soluble coolant. In the previous study, it was confirmed that the tool life was improved by applying the micro bubble coolant to various machining operations such as drilling, turning and grinding. Also, purification effects of the micro...
