    摘要： A method and tool for fine machining an outside circumferential surface of radially outwardly expanded, ring-shaped workpieces having respective holes therein, the workpieces being combined to form a stack. The tool includes a clamping arrangement for clamping the stack; a pair of segments disposed adjacent the clamping arrangement, each of the segments having a segment surface defining a predetermined radius of curvature corresponding approximately to a nominal radius of curvature of each of the workpieces; and a grinding belt arrangement disposed adjacent the segment surfaces. The segments are moved into a processing position wherein the radii of curvature of respective ones of the segment surfaces share a common center point, the step of moving the segments including the step of advancing the segments toward the stack such that the grinding belt arrangement is brought into grinding contact with the stack and thereby assumes a contour of the segment surfaces. The stack is thereafter moved relative to the grinding belts. The segments are kept in their processing position during the step of moving the stack.

    摘要： In a method of manufacturing a side rail of a compound steel oil ring assembly in which a linear, strip-like wire material is passed between a plurality of pins and bent into an annular shape, a side of the side rail that will become the inner circumferential side thereof is brought into pressured contact with at least one pin formed to have a corrugated surface, thereby forming corrugations in the side of the side rail that will become the inner circumferential side thereof.

    摘要： METHODS, APPARATUS, AND IMPROVED STRUCTURE HAVING AS THEIR COMMON BASIS THE SEQUENCE OF COLLAPSING A PISTON RING IN A FIXTURE APPROXIMATING ENGINE BORE DIAMETER, AND LAPPING A LOCALITY AT THE SIDE OF THE RING WHILE SO COLLAPSED, UNTIL A CIRCUMFERENTIALLY CONTINUOUS PORTION-NARROW IN WIDTH AND PREFERABLY LINE SIZE-OF THE SIDE IS FLAT IN THE RNGE OF AT LEAST ABOUT 10 TO 5 LIGHT BANDS. THE BROADEST METHOD DISCLOSED IS THE USE EXCLUSIVELY OF RINGS SO SELECTED THAT THE INNER PERIPHERAL EDGE AT THE SIDE HAS ALL POINTS THEREON IN

    COPLANARILITY TO A DEGREE EQUIVALENT TO THE STATED RANGE TO SEAL IN ABSOLUTE LINE CONTACT.
