종래에 있어서 선박 엔진용 공급유니트의 캠샤프트(200)의 하우징 접속부(241~244), 편심작동부(231~234)를 연삭가공할 때에는 접속플랜지(210)를 연삭기계의 회전척에 척킹하고, 최종 하우징 접속부(244)의 측면에 장착한 센터지그판에 심압대 센터를 설치하였기 때문에 접속돌출부(220)를 연삭할 수 없게 되는 문제가 있었다.Conventionally, when grinding the housing connection parts 241 to 244 and the eccentric operation parts 231 to 234 of the camshaft 200 of the supply unit for a ship engine, the connection flange 210 is chucked to the rotating chuck of the grinding machine. , Since the tailstock center was installed on the center jig plate mounted on the side surface of the final housing connecting portion 244, there was a problem that the connection protrusion 220 could not be ground.

이에 접속돌출부(220)를 연삭할 때는 캠샤프트(200)를 반대쪽으로 뒤집어서 최종 하우징 접속부(244)를 연삭기계의 회전척에 척킹하고, 접속돌출부(220)의 측면의 중심홈(251)에 심압대 센터를 설치한 후 접속돌출부(220)를 연삭하여야 했다.Accordingly, when grinding the connecting protrusion 220, the camshaft 200 is turned over to the opposite side, the final housing connecting part 244 is chucked to the rotating chuck of the grinding machine, and the shim is inserted into the central groove 251 of the side surface of the connecting protrusion 220. After installing the push-in center, the connection protrusion 220 had to be ground.

이처럼 종래에는 한번의 척킹으로 모든 연삭부위를 연삭가공하지 못하고 접속돌출부(220)를 연삭가공하기 위해서는 중량체인 캠샤프트(200)를 뒤집어서 다시 척킹한 후 연삭작업을 실시해야 했기 때문에 생산성이 크게 저하되는 문제가 있었다.In this way, in the prior art, since all the grinding parts cannot be ground with one chucking, and the grinding process of the connecting protrusion 220 is to be reversed, the heavy chain camshaft 200 has to be chucked again and then the grinding work has to be performed. There was a problem.

또한, 종래에는 동심으로 설정되는 접속돌출부(220)의 중심을 하우징 접속부(241~244)의 중심과 정확하게 일치하도록 연삭가공하기 어렵게 되는 문제가 있었다.In addition, in the related art, there has been a problem that it is difficult to grind the center of the connection protrusion 220 set concentrically to exactly match the center of the housing connection parts 241 to 244.
