ABSTRACT:
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.
