Manufacturing method and wheel of light metal vehicle wheel with high fatigue strength and light weight of metal

摘要

The present invention provides a surface processing method and a light weight wheel for improving the fatigue strength of a light alloy wheel for a vehicle and reducing the thickness of a part to reduce the weight of the wheel and at the same time achieve an excellent gloss surface.;The light alloy wheel is filled with relatively heavy specific steel or stainless steel and other shaped media with rounded corners in the barrel, and a vibrating vibrating vibrates the media on the wheel surface to form a hardened layer. At the same time, a smooth and glossy wheel surface close to the mirror surface is obtained.
