摘要： The invention relates to a method for producing rotationally symmetrical components made of metal, in particular steel, in which a blank is arranged on a first receptacle for rotation therewith, the receptacle is made to rotate about an axis of rotation, and so the blank is set in rotation about this axis of rotation. In addition, the invention relates to a device for producing a rotationally symmetrical component made of a metal, in particular steel, from a blank, comprising a receptacle for a blank made of metal, in particular steel, which is rotatable about an axis of rotation, and forming means, with which a contour can be formed into the blank. The object of providing a method and a device for producing rotationally symmetrical components with which rotationally symmetrical components made of metal, in particular steel, even of a complex geometry, can be produced with sufficient accuracy and reduced process times, is achieved with a method by at least one linear moulding element being moved tangentially in relation to the surface of the synchronously rotating blank with a contour that at least partially comprises an unrolled outer contour of the rotationally symmetrical component or a preform of the component, wherein the linear moulding element is at the same time pressed against the blank in such a way that an impression of the contour of the moulding element is at least partially formed into the blank during the tangential movement.
