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.
A flat circular blank is mounted on the spinning lathe and
with a series of roller passes, the material "flows" and is
laid down onto a mandrel that is the ID profile of the desired
finished part.
The mandrel is typically referred to as a "Spin Chuck" and
is usually made from wood or steel. Wood tooling is often
used for short-run or prototype work. Steel tooling is used when
tighter tolerances are required and for longer running production runs.
Both wood or steel spin tooling is far less costly than the tooling required
for other metal forming processes.
