Hub machining process

The wheel machining process is a complex and delicate process involving multiple steps and key components. Below is a detailed description of the wheel machining process:

Melting and refining: Wheel manufacturing first begins with the melting and refining process. The melting equipment requires strict control of the furnace temperature to ensure the quality and performance of the metal liquid. The main refining methods for refining aluminum liquid are gas method and melt method, through which the impurities in the metal liquid can be removed and its purity can be improved.

Low-pressure casting: After the refining is completed, low-pressure casting is carried out. Low-pressure casting machine with holding furnace for melting pool type, by controlling the pressure in the furnace chamber and the flow rate of the metal liquid, so that the metal liquid under pressure into the cavity, and crystallization and solidification under pressure. This process feature makes the casting organization dense, good mechanical properties, high metal utilization.

Processing treatment: processing treatment includes heat treatment and machining. Heat treatment is through the heating and cooling of the way, change the internal organization of the metal material, in order to improve its mechanical properties and stability. Mechanical processing, on the other hand, includes milling, turning and other steps to finely shape and trim the hub to meet the design requirements.

Inspection and Painting: After the machining treatment is completed, strict inspections are carried out, including dynamic balance inspection and air tightness inspection, to ensure that the quality and performance of the wheels meet the standards. In addition, painting treatment is also carried out to improve the aesthetics and corrosion resistance of the wheel.
