Metal spinning, also known as spin forming or spinning, is a metalworking process by which a disc or tube of metal is rotated at high speed and formed into an axially symmetric part. Historically significant, the process has evolved significantly with advancements in technology, leading to the development of new techniques and applications in various industries. This article provides a comprehensive exploration of metal spinning, covering its history, principles, techniques, materials, equipment, applications, and recent technological advancements.
There are several variations of metal spinning, each suited to different applications and material types:
Conventional Spinning: This involves simple shapes and is the most basic form of metal spinning, often used for producing cylindrical or conical parts.
Shear Spinning: Also known as flow turning, this technique involves thinning the material as it is spun, allowing for the production of stronger, lightweight components.
Tube Spinning: This method is used for shaping tubes and involves the axial stretching and thinning of the material.
Hot Spinning: In this process, the metal is heated to make it more malleable, allowing for the forming of harder metals or more complex shapes.
