Micro cutting of ferrous materials using diamond tool under ionized coolant with carbon particles

摘要

A new coolant for micro cutting of ferrous materials using a diamond tool was proposed. The effects of the new coolant (ion-shot coolant) which consists of ionized coolant and carbon particles on two steel materials, a high carbon chromium steel and a pre-hardened mold steel were investigated. Also mechanism of the ion-shot cutting was discussed by the observation on material structure at the primary shear zone and frictional coefficient between diamond tool and ferrous material. The ion-shot coolant showed great potential for the used of the diamond tool on ferrous material in terms of tool wear and surface quality.
