Abstract
The invention relates to a method of finishing cage windows in a ball cage for a constant velocity universal ball joint. The ball cage for use with the present invention has the shape of an annular member which comprises two parallel annular edges and a convex outer face. On the outer face, there are punched uniformly circumferentially distributed cage windows each having two circumferentially extending edges. The circumferentially extending edges of the cage windows are smoothed and parallelized by a non-chip-producing method of deformation.
