What is Metal Spinning?

Metal spinning usually starts with a circular blank, which is clamped against the shaped spinning mandrel by the spinning machine's hydraulic tailstock. The disc and mandrel rotate together, and the part takes shape as a roller gradually forms the material to the required shape, via a number of programmed passes. During the process the material becomes 'plastic', typically enhancing the physical properties of the material; this is one of the many features of the spinning process that attracts designers most. The spinning process also results in a higher material yield, and can eliminate or greatly reduce the time needed to machine the final product profile. This is particularly evident when converting a shape from an alternative forming processes, such as casting or forging to spinning, providing the customer with a reduced total project cost and process time.
