Patent ID: 8302314

Claim:
A method for manufacturing internally and/or externally profiled rings from tubular starting material, the method comprising the steps of: clamping in a clamping position on a spindle a tubular starting material having an axial length greater than an axial length of a profiled ring to be manufactured; roll forming in said clamping position an end section of the tubular starting material to shape at least one ring profile; performing in said clamping position prior to, parallel to, or after the roll forming process machine-cutting on the end section or on the at least one ring profile; generating during the roll forming process an axial counterforce at an end face of the end section of the tubular starting material relative to a flow direction of the tubular starting material by an axially arranged counterpressure tool so that a material flow in at least one of an axial direction and a radial direction of the tubular starting material is controlled such that flowing material is integrated into the ring profile; cutting off in said clamping position the at least one ring profile from the tubular staring material as a completely grinding-ready profiled ring.
