Abstract: 본 발명은 공작기계의 회전축에 장착하되 단면상태에서 보았을 때 외경에서 내경으로 갈수록 점차 양측으로 65°내지 85°의 면치각도를 갖도록 경사면이 형성된 몸체와; 상기 몸체의 외경에서 1㎜ 내지 5㎜의 절삭두께를 갖도록 수직방향으로 설치된 다수의 절삭팁과; 상기 경사면에 대응되도록 설치된 다수의 면치팁으로 구성되는 면치 겸용 절삭공구를 제공하기 위한 것으로, 본 발명은 원형관의 절삭과 면치가공을 동시에 진행하여 가공시간을 단축함과 동시에 생산효율을 증대시킬 수 있는 효과를 갖는다. 또한, 본 발명은 원형관의 절삭면과 면치면을 동시에 균일하게 가공하여 생산품질을 향상시킬 수 있는 효과를 갖는다. 아울러 본 발명은 종래와 같이 원형관의 절삭과 면치를 위한 각각의 작업인원이 필요하지 않으므로 인건비용을 절감하여 경제적인 이익을 창출할 수 있는 효과를 갖는다.
