Furrer, Ladish Company METAL SPINNING is a term used to describe moved either manually or hydraulically over components with thick sections or for alloys the forming of metal into seamless, axisym- the mandrel to form the component, as shown in with low ductility. Typical shapes that can metric shapes by a combination of rotational Fig. 2. The forming operation can be performed be formed using manual metal spinning are motion and force (Ref 1–4). Metal spinning using several passes. shown in Fig. 3 and 4; these shapes are difficult typically involves the forming of axisymmetric Manual metal spinning is typically performed to form economically using other techniques. components over a rotating mandrel using rigid at room temperature. However, elevated- Manual spinning is only economical for low- tools or rollers. There are three types of metal- temperature metal spinning is performed for volume production. Manual metal spinning is spinning techniques that are practiced: manual (conventional) spinning (Ref 1, 2), power spin- ning (Ref 4–11), and tube spinning (Ref 7, 8). The first two of these techniques are described in this article. Tube-spinning technology is de- scribed in the articles “Flow Forming” and “Roll Forming of Axially Symmetric Components” in Metalworking: Bulk Forming, Vol 14A of ASM Handbook, 2005.
