Abstract
The invention relates to a process for the finishing of ball cages (1) destined for constant-velocity joints which are provided with spherical annular inner and outer bearing surfaces (3, 2) and ball pockets (4) for the accommodation of torque-transmitting balls. In order that the finishing of such ball cages (1) can be carried out rapidly, at low cost and in as fully automated a manner as possible it is proposed according to the invention that the finishing both of the inner and outer spherical annular bearing surfaces (3, 2) as well as the contact surfaces (5) of the ball pockets (4) located opposite one another in the axial direction and each for one ball ensues by means of lathe machining.
