Abstract:
An inner surface super-finishing apparatus includes: an inner surface grinder (200) including: a film grinding material (202) grinding a surface of the object; a feeding roller (204) for feeding the film grinding material (202); a collecting roller (206) for collecting the film grinding material (202) used for grinding the object; supporting rollers (208) and (208') for supporting the film grinding material (202); a grinding head (210) protruding to one side and supporting the film grinding material (202) such that the film grinding material (202) contacts an inner surface of the object; a plunger (220) for supporting the grinding head (210); and a shaking member (230) installed on a right side of the plunger (220), for allowing the plunger (220) to reciprocate in a predetermined interval; a horizontal transferring member (110) for forcing horizontal movement of the inner surface grinder (200); a back- and- forth transferring member (130) for forcing back- and- forth movement of the inner surface grinder (200); and an object supporting member (280) installed on one side of the inner surface grinder (200), for supporting and rotating the object (W).
