METHOD FOR MANUFACTURING A ROTATIONALLY SYMMETRICAL SHAPED ARTICLE

摘要

A method for manufacturing a rotationally symmetrical shaped article (1) that is manufactured in a shaping process and has a cylindrical, concentric hub (4) which is axially closed on one side is devised in such a way that at least one pressure roll (8) is in contact with a rotating, closed, planar circular blank sheet (2) and presses the material of the blank radially from the outside inward against a projecting part (6) that runs upright on the circular blank (2) such that the thickness of the circular blank (2) decreases and the hub (4) comprising a blind hole (13) is formed.
