ABSTRACT:
A method of producing a sliding sleeve for gearshift mechanisms includes two forming steps. In the first forming step a preform, which has been pushed onto a tool mandrel with an external toothing, is formed by roller spinning so as to form on the inner circumferential surface of the preform the toothing implemented on the outer circumferential surface of the tool mandrel. Subsequently, the thus formed preform is formed by profile rolling on its outer circumferential surface so as to obtain a formed part. Finally, the tool mandrel is removed from the formed part.
