The Basics of Aluminum Metal Spinning

Metal spinning is the art of transforming a flat piece of metal into a rounded object on a lathe. Metal spinning is often used to create prototypes for various industrial objects, including machine parts, kitchen pots and pans, andfavicon tools. The process of creating spun metal is fascinating. Learning more about the basics of blank aluminum spinning can help you understand a little more about the metalworking industry and how products are created.

  1. A special mandrel is fitted onto the metal lathe to help shape the metal as it spins on the lathe. The worker places the aluminum blank onto the lathe and prepares to start the spinning process.
  2. The worker turns the lathe on and the metal starts to bend to the match the shape of the mandrel specific shapes as it spins, such as by turning the lip over to create a rounded edge, or by denting a part of the metal to create ridges in the aluminum.
  3. Once the aluminum piece has the desired shape, the worker turns off the lathe. The metal is usually hot from the speed at which it was turning, so the worker must wait a few minutes to remove the newly shaped aluminum or use gloves to protect his hands while removing the metal. Once the metal is finished, it has a high shine from the spinning and shaping process.

Some companies use blank aluminum spinning to create all of their products, while others use it only for creating the prototype of any item. It takes great skill to form a blank into a 3D shape without warping or damaging the metal in any way, which is why many hand-formed metal pieces are more expensive than those created by other methods, such as through pressure shaping.
