B25 Investigation of the effects of an electrolytic coolant with a nano carbon additive in diamond micro cutting on ferrous materials(Advanced machining technology)

Abstract

A special coolant system called 'Ion-shot coolant system' which consists of an electrolytic liquid and a nano carbon additive was developed. A series of experimental studies had been conducted to understand the effects of the coolant in micro cutting of two steel materials with different carbon content, a high carbon chromium steel (SUJ-2) and a pre-hardened mold steel (HPM38) using a diamond tool. Significant improvement of the diamond tool life was observed while cutting ferrous materials. Additional benefits of the ion-shot coolant system were discussed in this paper.
