CNC metal spinning

Description

• Metal spinning is a metalworking process that involves the application of force by a roller in order for the workpiece, which is spinning at high speeds, to conform to the contour of the mandrel. Metal spinning transforms a flat or preformed metal sheet into an axially symmetrical figure.
• A lathe machine is adapted for the metal spinning process. The components of a metal spinning lathe are the mandrel, roller, tailstock, headstock, spindle, and follower.
• Conventional metal spinning increases the depth of the workpiece while maintaining its material thickness constant.
• In shear spinning, the material thickness of the workpiece is reduced while maintaining its diameter constant. The depth of the workpiece also increases.
• Hot spinning is used for materials that are difficult to deform at room temperature. It is used when the material has low ductility and malleability.
• Multiple pass spinning is used when producing parts with sharp and complex designs. It also ensures uniform thickness.
• Tube spinning is a form of shear spinning, which elongates hollow, cylindrical tubes.
• Ideal materials for the metal spinning process are metals that can be deformed on a mandrel and lathe or can be metal stamped. Metals commonly formed by metal spinning are aluminum, steel, brass, bronze, Hastelloy, and titanium.
• Metal spinning specializes in creating hemispheres, cones, cylinders, parabolas, and venturis. It is an ideal fabrication process for constructing tank heads.
• Spun parts are seamless; this makes them durable. Metal spinning also improves the mechanical properties of the metal by refining its grain structure.
