Abstract

금속 부분(1)의 원추형 표면(3)은 연마석(9)의 표면과 마찰 접촉된다. 상기 금속 부분(1)은 원추형 표면(3)의 축(4)주위로 회전한다. 연마석(9)은 랭핑중의 전진을 유발하기 위해 원추형 표면(3)의 정점 각도의 절반에 해당하는 각도만큼 상기 원추형 표면의 축(4)에 대해 경사진 방향과, 상기 원주형 표면(3)의 축(4)과 수직방향 방향(23)으로 왕복 병진 운동한다. 래핑장치는 지지체(7)상에 장착되는 스톤(9)과, 지지체(7)를 원추형 표면(3)의 모선 방향으로 왕복 병진 운동시키기 위한 수단을 구비한다.The conical surface 3 of the metal part 1 is in frictional contact with the surface of the abrasive stone 9. The metal part 1 rotates about the axis 4 of the conical surface 3. The abrasive stone 9 is inclined with respect to the axis 4 of the conical surface and the cylindrical surface 3 by an angle corresponding to half of the apex angle of the conical surface 3 to cause advancement during the mapping. It reciprocates in the vertical direction (23) with the axis (4) of. The lapping apparatus has a stone 9 mounted on the support 7 and means for reciprocating the movement of the support 7 in the busbar direction of the conical surface 3.
