Metal Spinning Process

Metal spinning is a forming process designed to produce circular, hollow metal components. A flat metal disc is rotated on a specialized lathe and pressed against a spinning mandrel or block using a follower. Spinning tools or rollers apply controlled pressure to shape the disc into the desired form.

Key process details include:

Thickness Control: Finished parts can achieve a material thickness reduction of 10% to 50%.

Cost Efficiency: Low fixed tooling cost and flexible production setup; typical cycle times range from 2 to 20 minutes per part.

Material Flexibility: Ideal for pliable metals such as O-temper aluminum, light-gauge steel, and stainless steel.

CNC Multi-Pass Spinning: Suitable for short runs of challenging materials or high-volume production where consistency is critical.

Shear Forming / Flow Turning: Produces conical shapes and preforms with high repeatability and excellent surface finish.

This process allows for economical production of high-quality, precision metal components, making it widely used across industrial, aerospace, automotive, and lighting applications.
