피복 초경 공구의 마모

Abstract

피복(TiC, TiN)초경공구와 초경공구(P20)의 내마모성을 비교한 결과, 피복초경공구의 내마모성이 초경공구에 비해 3~4배 크다는 것을 알 수 있었다. 피복초경공구의 절삭력 및 절삭온도가 초경공구보다 낮다는 것을 알 수 있었고, 이는 낮은 절삭력과 절삭온도로 인하여 피복초경공구의 내마모성이 향상된다는 다른 연구결과와도 일치하였다.

By comparing the wear resistance of coated WC insert tool (TiC, TiN) and WC insert tool (P 20), it was shown that the wear resistance of coated WC insert tool is 3~4 times greater than that of WC insert tool. It was known that the cutting force and temperature of coated WC insert tool is lower than those of WC insert tool, and this result coincided with the result of other study saying that the lower cutting force and temperature increase the wear resistance of coated WC insert tool.
