Abstract

The precise and economical production of high-strength die is demanded. Mirror surface processing is essential for such a precision product. An ultra-precision diamond cutting technique is widely applied to mirror surface finishing of soft-metal materials such as copper and aluminum, while the diamond cutting is not completely available to ferrous materials like carbon steel.This study was performed to examine the effect of the CO2 gas blow atmosphere and the cutting conditions on the reduction of tool wear and the improvement of surface finish in the ultra-precision diamond cutting of the carbon steel. The experiments of the precision cutting of S25C and S55C were carried out under cutting speed of 47,94 and 188 m/min and the effect of the machining atmosphere on the tool wear and the surface roughness were discussed. As a result, especially under cutting speed of 188 m/min the tool wear was reduced and the surface roughness was improved by cutting of both S25C and S55C in CO2 gas blow atmosphere.
