Points needing attention in the manufacturing process of automobile wheel hub

A very important step in automobile processing is to replace the wheel. Because the appearance cost of the original wheel is mostly ordinary, and it cannot show the personality of young people, therefore, with people's increasingly demanding products, full-size aluminum alloy wheels are 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, has good appearance quality and is not easy to fall off. As an improvement, the wheel is first heated, then sprayed, then sprayed with powder, and then cured, cooled and polished.

Good automobile hub processing technology, coating, drawing and recoating on the surface of the hub, greatly improves the three-dimensional feeling and texture of the aluminum alloy hub. The paint surface is stable and not easy to fall off, ensuring the appearance and quality of the hub.

In terms of polishing, frequency conversion technology is used to control the rotation speed of the polishing machine, so that the polishing machine can polish on the windows and wheel edges. The rotation speed of the polishing machine is controlled at 300r / min, and the process parameters are checked to determine the polishing accuracy of the hub, wheel edges and other parts, and the hub and wheel edges are polished.
