Metal Spinning

Metal spinning is a process by which circles of metal are shaped over mandrels while mounted on a lathe by the application of levered force with various tools. It is performed rotating at high speeds on a spinning lathe. The flat metal disc is spun against the mandrel, and a series of sweeping motions then evenly transforms the disc around the mandrel to the desired shape.

When metal spinning is done by hand, care must be taken not to touch the spinning metal with one's hands until the metal edge has been turned over and rolled to a rounded edge so that the care edge of the stock is protected.
