What is Metal Spinning?

Metal spinning is a form of symmetrical metalworking where a flat circle, or circular, piece of metal is fitted into a hand lathe or CNC lathe. Held in place by a pressure pad, the metal disk is spun at an appropriate speed. A localized force utilizing a variety of rollers or tools is applied either by hand or by machine to gradually form the metal over a 'chuck' or mandrel. In complex spinnings, multiple chucks may be used to accomplish a specific shape.
Chucks are made from hardened metals or wood (see Special Considerations).

Spindustries works with a wide variety of materials including aluminum, copper, brass, stainless steel, and mild steel. While some materials can be spun cold, others require annealing to be shaped effectively.
