Metal Spin Forming is the process of moving a spinning roller over a metal blank. The metal spinning process starts with a sheet metal blank that rotates on a lathe. The metal disc is pressed against a tool with a tailstock. The metal disc, tailstock and tool rotate in a circular motion and a roller manipulated with CNC controls presses against the metal to form the metal over the tool through a series of passes by the roller. The resulting part is a piece that duplicates the exterior portion of the tool it was formed on.
