Abstract
The invention relates to a method for finishing the ball star of a homocinetic joint, especially for automobiles. The ball star has a ball ring-shaped bearing surface for mounting in a ball cage, and has a plurality of essentially axial running guideways provided for the balls. Said balls are arranged in the ball recesses of the ball cage and transmit torque between the ball cup and the ball star. In order to be able to finish such ball stars quickly, economically and as fully automatic as possible, the invention provides that both the ring-shaped bearing surface provided for mounting in the ball cage as well as guideways provided for the balls are produced by a hard-rotary turning operation.
