Metal Spinning: A Complete Guide


Metal spinning—also referred to as metal turning or spin forming—is a forming process in which a flat metal disc is turned into a hollow component with a circular cross-section. The flat metal disc—i.e., the blank—is fixed to a spinning lathe. While it spins, a roller tool presses it against a mandrel, creating the desired interior form. The resulting component can take on a variety of basic shapes, including cones, cylinders, hemispheres, shells, and venturis. In any case, it is highly accurate with a compressed grain structure and smooth surface, both of which minimize the need for additional finishing.
