Abstract (en)
[origin: US2002020203A1] The invention relates to a method and a flow-forming machine for inserting a groove in a cylindrical, thin workpiece. The workpiece is rotated relative to at least one spinning roller. The spinning roller is provided with a profile corresponding to the groove to be shaped. The spinning roller is radially infed to the workpiece and the groove is shaped. A particularly precise forming of the groove is brought about in that simultaneously with the radial infeeding of the spinning roller and the shaping of the groove, the workpiece is axially upset by means of at least one punch.
