Spin Machining (commonly referred to as metal spinning, 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. This technique, rooted in ancient craftsmanship and refined through modern engineering, leverages the principles of plastic deformation to shape materials without removing significant amounts of material, distinguishing it from subtractive manufacturing methods like milling or turning. Spinning machining is widely utilized in industries such as aerospace, automotive, and consumer goods manufacturing, producing components ranging from cookware to rocket nose cones. This article explores the history, principles, techniques, materials, equipment, applications, and comparative analyses of spin machining, providing a detailed scientific overview of the process.
