Disc spring or wave spring manufacturing method for machine and equipment construction, involves exposing surface areas of disc spring or wave spring during stressing of spring, where surface areas are provided with stress in edge section

The method involves exposing surface areas of a disc spring (111) or wave spring during stressing of the spring, where the surface areas are provided with a residual compressive stress in an edge section. The surface areas are compressed in a circular movement of a ball or a roller around an axis of the spring relative to the spring, where the rolling compression takes place at an increased temperature of the spring. An independent claim is also included for a disc spring or wave spring. Verfahren zur Herstellung von Tellerfedern oder Wellfedern, an denen Oberflächenbereiche, die bei Belastung der Feder durch Zugspannungen beansprucht werden, mit einer Druckeigenspannung in der Randschicht versehen werden, wobei die genannten Oberflächenbereiche unter Zugspannung gesetzt und durch Kugelstrahlen verdichtet werden.
