摘要： A method of making self-tensioning rings, including the steps of circumferentially machining an out-of-round ring blank on inner and outer surfaces thereof and subsequently cutting a ring segment out of the ring for obtaining a ring gap therein; measuring a circumferential contour of the ring subsequent to the machining step; and calculating the circumferential length of the ring segment and a cutting angle for removing the ring segment from the ring as a function of data obtained in the measuring step.

摘要： Machining the circumferences of workpieces, particularly piston rings, in a variety of out-of-round contours and diameters requires only a single copying disc having a basic out-of-round contour. The copying disc is driven in synchronism with the angle of rotation alpha of piston rings to be machined by a direct current servomotor and, in order to generate the desired out-of-round contour, is caused to deviate from its synchronous movement by pulses received from a computer for the leading and lagging difference angles of rotation delta phi. An adjustable coupling member is provided between a copying disc sensor (such as a double lever) and the tool holder for transferring the out-of-round contour from the copying disc to the workpiece.

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.
