A metal spinning machine includes a mandrel kept in rotation, a roller tool with which a plate blank workpiece is pressed against the mandrel to form the workpiece, linear motors that generate thrust force in proportion to driving electrical current and drive the roller tool, an operating lever that gives an operator command to the linear motor and a control unit that includes a memory. Manual operation of the roller tool with the operating lever by an operator receiving a teaching of the operator command forms the workpiece in a prescribed shape. The memory of the control unit stores the operator command that is then given to the linear motor to enable a same shape to be subsequently formed relative to plate blank workpieces repeatedly.
