A method for manufacturing a rolling-element bearing cage includes clamping a cage blank in the radial direction using a clamping element in a first position where the cage blank is processed. Then, the cage blank is rotated relative to the clamping element to a second position where the cage blank is further processed. A device for manufacturing a rolling-element bearing cage includes the clamping element, which remain stationary together with a tool for processing the cage blank, while only the cage blank is rotated.
A method (1) for manufacturing a rolling-element bearing cage, comprising:
The method (1) according to one of the preceding claims, wherein, when an embossing of cage bridges occurs in the processing (3, 5), the cage blank (7) is rotated with respect to the clamping element (6) far enough until one of the cage bridges abuts on a stop (35).
The method (1) according to one of the preceding claims, comprising:
The method (1) according to one of the preceding claims, wherein the cage blank (7) is clamped such that an axis of rotation (M) of the cage blank (7) is oriented parallel to an acting weight force of the cage blank (7).
A device (5) for manufacturing a rolling-element bearing cage, comprising:
