Abstract

원통 형상 공작물의 내면을 전해작용과 연마재에 의한 마찰작용을 복합하여 연마하기 위한 원통 형상 공작물 내면의 복합연마장치에 관한 것이다. 도전성인 회전축(2)에 유체압 공급공(3)이 형성되고, 회전축(2)의 선단부에는 원판 형상의 전극(4)이 장착된다. 전극(4)의 원주면 상에는 서로 원주 방향을 따라 일정한 간격으로 복수의 감합공(5)이 형성되어 있다. 감합공(5)에는 전극(4)의 직경방향을 따라 이동가능한 다이어프램(7)이 장착되고, 이 다이어프램(7)의 내부에서는 감합공(5) 부분과 유체압 공급공(3)이 관통공(6)에 의하여 연통되어 있다. 다이어프램(7)의 외면에는 연마재(11)가 장착되고, 이 연마재(11)는 다이어프램(7)과 함께 이동가능하게 되어서 원통 형상 공작물(1)의 내면에 대하여 압착과 분리를 자유자재로 실시할 수 있다.The present invention relates to a compound polishing apparatus of an inner surface of a cylindrical workpiece for polishing the inner surface of a cylindrical workpiece by combining an electrolytic action and a friction action by an abrasive. A fluid pressure supply hole 3 is formed in the conductive rotating shaft 2, and a disk-shaped electrode 4 is attached to the tip of the rotating shaft 2. On the circumferential surface of the electrode 4, a plurality of fitting holes 5 are formed at regular intervals along the circumferential direction of each other. The fitting hole 5 is equipped with a diaphragm 7 which is movable along the radial direction of the electrode 4, and the fitting hole 5 portion and the fluid pressure supply hole 3 are formed through the diaphragm 7. It is communicated by (6). An abrasive 11 is mounted on the outer surface of the diaphragm 7, and the abrasive 11 is movable together with the diaphragm 7, so that the inner surface of the cylindrical workpiece 1 can be pressed and separated freely. Can be.
