As outlined in The Library of Manufacturing’s article “Metal Spinning,” metal spinning is a precise manufacturing process used to form axis-symmetric parts by shaping sheet metal over a rotating mandrel. This method, also known as conventional spinning, is ideal for producing unique, large, or low-quantity parts with complex contours.
The process begins with a flat or preformed metal blank clamped between a mandrel and a tailstock. As the system rotates, a rounded tool or roller applies force to gradually form the workpiece over the mandrel, conforming to its shape. Metal spinning is typically performed cold, but can also be executed at warm or hot temperatures depending on the material and design requirements. The process is capable of forming parts up to 20 feet in diameter, making it a versatile option for large components.
