What is Metal Spinning Process?

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. The spinning could be done by either CNC lathe or by hand. Most of the time, the process of metal spinning involves the elimination of material in traditional metal or wood turning. As for the molding or forming of sheet material, it’s done over existing shape.

Metal spinning actually ranges from the specialty of the artisan to the most advantageous way of forming round metal parts mainly for commercial applications. Artisans are using this process in order to produce architectural detail, decorative household goods as well as urns and 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. As for the diameter and depth of the formed parts, these are limited by the equipment’s size.

Spinning process is fairly simple; in drive section of the lathe, formed block is mounted and pre-sized metal disk is clamped against the block with the use of pressure pad that’s attached to the tailstock. The workpiece and the block are rotated together at super fast speeds. 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 being removed from block however, several blocks may be required for more complex and sophisticated shapes.

When working with extremely complicated shapes, it is spun on ice forms that melts after spinning. Because the final diameter of workpiece is less than the starting diameter, the workpiece ought to be thickened, buckled circumferentially and elongated radially.

When it comes to more complicated procedures, it’s otherwise called as necking or reducing that allows the spun workpiece to use reentrant geometries. If for example that the surface form and the finish is not that hard, the workpiece is spun on air and no mandrel ought to be used. If the form or finish is hard however, it will demand eccentrically mounted mandrel.

There are metal spinning tools that are allowed on the bearings throughout the forming process. These tools help in reducing heating and friction of the tool, extending its life while improving the surface finish. To be able to extend the life of the tool, the rotating tools are coated using thin film of ceramic.
