Metal spinning or otherwise known as spinning, spin forming or metal turning is a process of metalworking by which a tube or disc of metal is being rotated at high speed and form into axially symmetric part. There are a couple of ways of how the spinning may be done such as CNC lathe or by hand. Metal spinning involves the removal of material as in traditional metal or wood turning. As for the molding or forming of sheet material, it’s done over existing shape.
In reality, metal spinning range from the expertise and experience of the artisan up to the most complicated and beneficial way to form round metal parts for commercial purposes. Artisans use this process to be able to produce architectural detail, decorative household goods as well as urns or even specialty lighting.
Commercial applications for metal spinning process is quite a lot and this includes rocket nose cones, cookware, gas cylinders, brass instrument bells, public waste receptacles and so forth. Virtually, any kind of ductile metal could be formed from stainless steel or aluminum to high temperature, high strength alloys. Both the depth and diameter of formed parts are only limited by the size of available equipment.
The process of spinning is quite simple; in drive section of lathe, a formed block will be mounted and then, pre-sized metal disk is clamped against the block using pressure pad, which is attached to tailstock. At high speeds, the block and the workpiece are being rotated together. Local force is applied in the workpiece in order to make flow to the block. Normally, the force applied is through the use of different levered tools. Simple workpieces are removed from the block but more complex shapes might require several blocks.
