METAL SPINNING / DESIGN SUGGESTIONS

As previously pointed out, the metal spinning process is generally limited to symmetrical shapes of circular cross-section. However, welding and machining techniques can be combined with spinning to achieve a broad variety of configurations. Flowing contours are preferred since sharp corners and extremely small radii cannot be achieved without further machining, if at all. A good rule of thumb for designers is to allow 1 - 1 1/2 times the metal thickness as a minimum radius for spun parts. The cone, hemisphere, and straight-sided cylinder are the basic shapes from which many spun parts are developed.
