metalworking process by which a disc or tube of metal is rotated and formed into an axially symmetric part; it does not involve removal of material

Metal spinning is a process where a piece of sheet metal is rotated on a machine (often a lathe) to produce an object.[1] The object usually has the qualities of being round, hollow and symmetrical.[1] Metal spinning dates back thousands of years to Ancient Egypt.[1] It is closely related to the potter's wheel.

The process begins with a flat piece of metal or a metal cylinder.[2] It is cut to a specific size based on the size of the finished part. A form is used to create the internal shape of the spun metal part.[2] The form is often made of aluminum or hardened steel.[2] Metal spinning used to be used for creating prototypes and where only a few parts needed to be made.[3] With the introduction of automatic lathes, metal spinning can be used to create a larger number of parts inexpensively.[3]
