All About 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. Metal spinning involves the removal of material as in traditional metal or wood turning. However, forming or molding of sheet material is over an 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. Click here to learn more!
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. Basically almost any type of ductile metal can be formed form aluminum or stainless steel to high strength and high temperature alloys. But you should know that for the diameter and depth of the formed parts, this will be limited only to the size of equipment, discover more here!
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. 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. Oftentimes, there are different levered tools used in applying force. Simple workpieces are removed from block but there are more complex shapes that require several blocks.
As for extremely complicated shapes, it can be spun on ice forms which 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.
For more involved process that is referred to as necking or reducing, it lets the spun workpiece to integrate 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 for example that the form or finish is critical, then it will require 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. To know more about welding, visit this website at https://en.wikipedia.org/wiki/Talk%3AWelding.
