What is metal spinning ?
Metal spinning is a rotary forming process for the production of hollow,rotational symmetrical parts in sheet metal .The starting blank is usually a flat disc but may also be a tube or a pressed preform,in a series of sweeps and employing a forming roller.the metal is progressivelt shaped onto a mandrel conforming to the internal form of the finished part whilst the workpiece is rotated.
why spin rather than press?
In general ,spinining offers flexibility with low tooling costs and is widely used for low-tomedium-volume production.Depending on the application,spinning can offer major benefits which makes it first choice,even for high-volume production.production machines can be configured with a range of attachments to produce a finished part in one hit eliminating secondary operations.each case needs to be examined on its own merits
