The present invention relates to a method for producing a ball-guided snap-action cage (16, 30, 32) for ball bearings having the following steps: - provision of a semi-finished product with a circularly annular end section or of an annular blank; - provision of a cutting tool (34) which has a continuous blade (35), comprising a part (36) which projects at the free end (38) of the cutting tool (34) and a shank (37) which is set back with respect to the former; - production of at least one ball pocket (18) by means of the cutting tool (34), comprising a substantially cylindrical spherical cap (20) and at least one snap-action edge (22) which covers the spherical cap (20) partially, wherein the production of the ball pocket (18) comprises the following steps: - lowering of the rotating cutting tool (34) in the axial direction of the circularly annular end section or of the annular blank as far as a dimension b below the upper edge of the circularly annular end section or of the annular blank, wherein the rotation centre point of the cutting tool (34) is offset by a dimension a from a predefinable spherical-cap centre point transversely with respect to the axial direction of the circularly annular end section or of the annular blank; - moving of the rotating cutting tool (34) transversely with respect to the axial direction of the circularly annular end section or of the annular blank by the dimension a, in such a way that the rotation centre point of the cutting tool (34) and the predefinable spherical-cap centre point coincide; - further lowering of the rotating cutting tool (34) in the axial direction of the circularly annular end section or the annular blank by a dimension c with the formation of the spherical cap (20). |
