How "Powerful" Is Powerful Spin Compared To Normal Spin?

Powerful spinning is a kind of spinning process which can change the shape and thickness of metal. When spinning, the blank is fixed in the mold by tail top or other ways. The mold is rotated and the rotation is used to make the feed movement, so that the blank is continuously thinned point by point and attached to the mold to form the required shape parts. The powerful spinning mainly depends on the thinning of the thickness of the blank to realize the forming of the workpiece. As the strength of the spin required for the powerful spin is more powerful, so the spinning machine for the powerful spin processing is called the powerful CNC spinning machine. So what's so much more powerful about powerful spinning than normal spinning?

(1) Powerful spinning technology can effectively reduce the design wall thickness of parts, reduce weight, and improve the fatigue resistance of products;
(2) Spinning is local continuous processing, the instantaneous deformation area is small, the total deformation force required is small, the processing equipment requirements are simple, the mold cost is low;
(3) Spinning is a non-cutting process with high material utilization, which is conducive to reducing production costs;
(4) The dimension tolerance and shape tolerance of spinning forming parts are small;
(5) Spinning belongs to axial drawing forming, and the material in the deformation area is in the state of two-or three-way compressive stress, so it can achieve a higher degree of deformation.

There are many materials that can be processed by powerful spinning. In addition to common aluminum alloy, stainless steel, titanium alloy, high temperature alloy and other hard deformation materials can be processed into various products by powerful spinning.

The strength, hardness and fatigue resistance of parts can be improved after powerful spinning. Therefore, spinning technology has been widely used in the manufacturing of parts and components in the fields of automobile, military industry and aerospace.
