Metal Spinning, also known as spin forming, spinning or metal turning is a metal forming process that uses a disc or tube of metal that is rotated at high speed and formed into an axially symmetric part. This process uses cold work metal. Spinning is performed by hand or by a CNC lathe machine. A great advantage to metal spinning is that forming parameters and part geometry can be altered quickly, and at a lesser cost than other metal forming processes. This process can be used for both larger and small production quantities.
