Abstract

피복경질 합금공구는 프랭크면(4)과 절삭면(6)의 연결부를 이루는 절단날 능선부(3)에 칼날끝 처리부를 갖는 경질합금 기본재료(1)와, 해당 경질합금 기본재료(1)의 표면에 피복된 피복막(2)을 구비하며, 피복막(2)의 표면의 절단날 능선부93)에 표면처리부를 갖고 있다. 이 피복경질 합금공구의 특징은 경질합금 기본재료(1)의 표면에서 프랭크면(4)과 칼날끝 처리부의 경계부에 형성되는 볼록면의 곡율반경을 Rs1, 피복막(2)의 표면에서 프랜크면(4)과 표면 처리부의 경계부에 형성되는 볼록면의 곡율반경을 Rc1, 칼날끝 처리부이외의 영역의 피복막(2)의 평균막을 d로 했을 때, Rc1(Rs1+d)1.0 으로 되도록 피복막(2)이 형성되어 있는 것에 있다. 이 구조에 의하면, 내결손성을 손상하지 않고 내마모성을 향상한 수명이 긴 피복경질 합금공구를 제공할 수 있다.
