Abstract
Description
섕크, 클램핑연결부(clamping connector) 및 나이프 헤드로 구성되는 절삭가공공구가 미국특허 제 5,899,642 호에 의해서 공지되어 있다. 클램핑연결부와 나이프 헤드간 결합이 형상접속적 결합 및 마찰접속적 결합에 의하여 이루어지며, 클램핑연결부가 공구에 의하여 섕크에 고정되기 전에 나이프 헤드가 공구에 의해 클램핑연결부에 먼저 고정된다. 종래기술의 이러한 실시형태에서는 클램핑연결부를 이용할 필요가 있으므로 한편으로는 나이프 헤드를 고정하는데 비용이 많이 들고, 다른 한편으로는 클램핑연결부를 이용함으로써 공구에 불평형 문제가 발생되고 이 때문에 공구의 사용수명이 단축되는 결점을 갖는 것으로 생각된다.
Claims (4)
- 회전하는 공구의 형태로 형성되어 있고, 클램핑되어 기계 또는 기계 스핀들 내로 들어갈 수 있는 섕크를 가지고 있으며, 이 섕크의 자유단에는 나이프 헤드가 설치되어 있고, 삽입부는 섕크와 일체로 형성되어 있으며, 나이프 헤드는 삽입부 홀더로서 삽입공을 가지고 있고, 삽입부 홀더가 삽입부 상에 장착되어 꽉끼여지고 마찰접속적 결합에 의하여 삽입부에 조여질 수 있는 절삭가공공구에 있어서, 삽입부(4)를 포함한 섕크(2)가 일체형으로 구성되어 있고, 섕크(2)의 삽입부(4)와 이에 대응하는 나이프 헤드(5)의 삽입공(6)은 각각 나사부(7)와 압력끼워맞춤부(8)를 가져서 형상접속적 결합 및 마찰접속적 결합이 이루어지게 하되, 섕크(2)의 압력끼워맞춤부(8)에는 나이프 헤드(5)의 압력끼워맞춤부(8)의 열수축끼워맞춤을 수행하기 위해 잉여형성부(9)가 형성되어 있는 것을 특징으로 하는 절삭가공공구.
- 제 1 항에 있어서, 압력끼워맞춤부(8)가 원통형 또는 원뿔형으로 형성되어 있는 것을 특징으로 하는 절삭가공공구.
- 제 1 항에 있어서, 삽입부(4)를 포함한 섕크(2)가 단일체의 초경금속 또는 중금속으로 만들어지며 나이프 헤드(5)가 강철, 티타늄 등으로 만들어진 것을 특징으로 하는 절삭가공공구.
- 제 1 항 내지 제 3 항 중 어느 한 항에 있어서, 상기 마찰접속적 결합은 가열공정에 의해 형성되고 다시 해제됨을 특징으로 하는 절삭가공공구.
