Abstract
A method for producing a profiled hollow shaft for a telescopic steering shaft of a motor vehicle may involve providing a hollow shaft to be processed, a profile mandrel, and a roller head comprising at least one roller. The method may further involve introducing the profile mandrel into the hollow shaft in order to produce a groove in the hollow shaft. The method may also involve moving the profile mandrel and the hollow shaft together relative to the roller head, wherein movement of the profile mandrel and the hollow shaft relative to the roller head is performed exclusively in a direction of a longitudinal axis of the hollow shaft in order to form a groove.
