Abstract

A production method involving forming an inner joint part of a constant velocity universal ball joint in the form of a hub member () which comprises a central through-aperture () with inner toothing () for receiving a shaft journal (), and ball tracks () for receiving torque transmitting balls on the outer circumference, wherein a blank with largely finish-formed ball tracks is produced by non-chip-forming deformation; wherein, at the blank, outer surfaces and a smooth through-aperture () are finish-turned; and wherein, during simultaneous working stages, the ball tracks () are calibrated by non-chip-forming deformation and the inner toothing () in the through-aperture () is produced by pressing in a non-chip-forming way.
