Metal spinning is treated as the new edge process with several benefits over other metal forming processes like deep drawing, blanking, collar forming, etc. It is basically classified as the tensile and compressive forming type manufacturing process. Various types of shapes are produced with metal spinning process. Generally, metal spinning is used to produce symmetrical shapes like a cone, bowl, dish, etc. Shell and tube spinning process is used with spinning(Tschaetsch, 2007), when the wall thickness is intended. The metal spinning process connects the craftsman and modern machine tool of present and futures. Automation in spinning is preferred for the mass production of the identical symmetric part. Conventional spin forming (manual spin forming) is applied for the intricate architectural and decorative products. Manual spin forming creates the smooth finishing product which has good mechanical strength and fine surface finish. Spinnability of the metal is an important parameter and is defined as the ability of sheet metal to undergo deformation by spinning without the wrinkles in the flange and no fractures on the wall.

Metal spinning is the process of forming three-dimensional symmetrical parts from flat circles of metal. Metal spinning provides an economical alternative to stamping, casting, and many other metal-forming processes. It is an excellent means of quickly prototyping round hollow metal forms (primarily the realm of expensive sheet metal stamping machinery). Metal spinning allows the production of hollow, axially symmetrical sheet metal components. The basic technique of spinning, which is common to this process, consists of clamping a sheet metal blank against a mandrel on a spinning lathe, and gradually forming the blank onto the mandrel surface with a roller, either in a single step or series of steps [113–115]. The profile of the mandrel is the ID profile of the desired finished part. A levered force is applied uniformly to the sheet metal by rotating the metal and its intended form (the mandrel) at very high rotational speeds, thus the sheet metal is deformed evenly without any wrinkling. The spinning process allows for the rapid production of multiple parts as well as quick reiteration since only the one tool (the mandrel) need be modified. The metal spinning process is explained in Figures 4.1 and 4.2.

Metal spinning is a sheet forming process in which sheet metal is rotated at high speed and formed by imparting sufficient local pressure on the workpiece using a roller or other similar tool. The finished part is axially symmetric with a reduced final diameter relative to the starting diameter (Lange 1985).
