Precision CNC Alloy Wheel Hub

Designed for high-end modified vehicles, drone landing gear, or automated equipment mobility systems, these disc-shaped structural components are formed using multi-axis联动 CNC milling. The main body features a typical rim profile, including an outer flange for tire or track installation, hollow webbing with support spokes, and a central bearing seat. The design balances lightweight requirements with high rigidity and load-bearing capacity, making it ideal for applications demanding strict rotational balance and superior surface finish.

The core of the manufacturing process lies in controlling the coaxiality and flatness of large-diameter disc parts, ensuring that the positional relationships between the center hole, bolt circle diameter (PCD), and outer diameter meet assembly tolerances. For the complex internal cavities and thin-walled spoke structures shown, appropriate clamping strategies are employed to suppress cutting deformation. We utilize vertical machining centers and Coordinate Measuring Machines (CMM) to strictly control dimensional accuracy and geometric tolerances on all mating surfaces.

Leveraging our Dongguan facility's expertise in precision machining of titanium and aluminum alloys, we offer full-cycle services from single-piece prototyping to batch delivery. Buyers need to provide 2D/3D drawings specifying material grades, surface treatment requirements (such as anodizing, sandblasting, or mirror polishing), and key inspection points. We evaluate costs and lead times based on drawing complexity, material utilization, and post-processing requirements, supporting custom development from drawings.
