A very important step of car refitting is to replace the wheel. Due to the cost, the appearance of the original automobile wheel hub is mostly ordinary, which can not show the personality of young people. Therefore, with the increasing demand for products, full-size aluminum alloy wheel hub is gradually emerging in the market.

　　In view of this, the aluminum alloy wheel hub is processed by wire drawing and spraying, which makes the wheel more beautiful, good appearance quality and is not easy to fall off. As an improvement, the wheel hub is heated first and then sprayed; after the powder is sprayed, it is solidified, cooled and grinded in turn.

　　Good automobile wheel hub processing technology is adopted. After painting and wire drawing on the surface of the wheel hub, the three-dimensional feeling and texture of the aluminum alloy wheel are greatly improved. The paint surface is stable and not easy to fall off, so as to ensure the appearance and quality of the wheel hub.

　　In terms of polishing, frequency conversion technology is used to control the speed of the polishing machine, so that the polishing machine can polish the window and wheel rim. The speed of the polishing machine is controlled at 300r / min. after checking the process parameters, the wheel hub window, wheel flange and other parts are determined, and the wheel hub window and flange are polished.
