1. Understanding Spin Forming

Spin forming, also known as spin forming or metal spinning, involves a rotating disc of metal being shaped into a desired form through the application of force. Here are the key aspects of the process:

• Rotation: The metal disc is rotated at high speeds on a lathe.
• Tooling: A tool is applied against the metal surface, gradually shaping it into the desired contour.
• Material Types: Common materials used include aluminum, stainless steel, and brass.
• Thickness Control: The process allows for uniform thickness, which is crucial for structural integrity.
