Briefly describe the limitations and advantages of CNC metal spinning

CNC metal spinning is a unique process that can be used to form complex shapes from aluminum steel, stainless steel, high strength and high temperature alloys, and many other metals. CNC metal spinning is a metal processing method by which a coil or tube of metal is rotated at high speed and formed into axially symmetrical sections, usually by hand or with numerical control techniques. Spinning metal is an inexpensive alternative to stamping process with faster processing times. Not only can a production prototype be run on the design, but most changes to the design can be done at no additional cost to the customer.

Since the spun parts have no seams, they are able to withstand higher internal or external pressures. This is due to the grain structure of the CNC metal spinning parts, which are realigned, improving metallurgy, as well as improving the tensile strength of the material. This also allows the use of lighter gauge materials, saving material costs. Some examples are diving tanks, CO 2 cartridges, and oxyacetylene tanks. CNC metal spinning can range from high volume production of small hardware items, such as metal tumblers and automotive parts, to large parts for aerospace applications to other products. CNC metal spinning can be used to cost-effectively produce single or small quantities of parts out of expensive materials, such as platinum, or high-volume parts of low-cost materials, such as aluminum. Cost savings are further enhanced from the inherent finish i.e. spinning, often eliminating the need for additional machining. Very low tool compared to stamping, and the advantages of extremely short setup and changeover times. The process is also environmentally friendly and produces less waste.

CNC metal spinning is an economical solution for those products that require structural integrity. A wide range of shapes can be produced with relatively simple molds.
