Investigation of the Effects of an Electrolytic Coolant with a Nano Carbon Additive in Diamond Micro Cutting on Ferrous Materials

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 (SUS420J-2) using a diamond tool. Significant improvement of the diamond tool wear was observed while cutting ferrous materials. Additional benefits of the ion-shot coolant system were discussed in this paper.
