See full text

A method for producing a ball raceway on a workpiece includes providing the workpiece, machining a preliminary thread profile on the workpiece and providing a thread rolling tool. The thread rolling tool has a tool shank, and the tool shank has a free end with a tool head having a roller profile. The method also includes clamping the workpiece into the thread rolling tool, rotating the workpiece about an axis of rotation, moving the tool shank longitudinally along the workpiece, and rolling the roller profile on the preliminary thread profile to generate a final thread profile.
