Flow Forming Process
7th July 2016
Metal-spinning includes fastening a pre-form (flat blank or preformed blank) centrically against the mandrel with the pressure plate and rotated by a friction lock via the main spindle drive. The spinning roller is locally applied to the circumference of the pre-form. The direct pressure effect of the spinning roller gradually applies the material to the tool in an alternating sickle-shaped movement between the bottom and the edge of the round. Then the finished part is put into its final shape by the smoothing overrun.
