发明名称 Method and apparatus for spinning
摘要 <p>The method involves arranging a tubular work piece around a pressure mandrel (20). The pressure mandrel is displaced by rotation, and is remodeled by feeding a shaping mandrel (40). Wall thickness of the tubular work piece is reduced, where the tubular work piece is lengthened. The pressure mandrel is displaced in the axial direction against the work piece during remodeling. An independent claim is also included for a flow form milling device.</p>
