CNC Precision Flange Bushing Assembly

As critical connection nodes in mechanical transmission systems and fluid pipelines, these disc-shaped and cylindrical structures feature a central through-hole and regularly distributed mounting holes on the periphery. They are primarily used for radial limitation, rigid docking, or sealed transitions of rotating shaft systems. Part forms include square flange bases, circular flange plates, and multi-step bushings, commonly found in automation equipment modules, instrument shaft supports, pneumatic/hydraulic interfaces, or fixture positioning stages. Bolt fastening ensures positional stability under high-speed rotation or pressure.

The core of the manufacturing process lies in ensuring the flatness of the end mounting surface, the perpendicularity of the inner hole axis relative to the end face, and the positional tolerance of each mounting hole. For bushing parts with multi-step features or internal/external threads, strict control of coaxiality between the outer diameter and inner hole is required to prevent skewing, uneven stress, or seal failure after assembly. For such hardware components featuring both polyhedral and rotational characteristics, we typically employ high-rigidity CNC machining centers combined with CNC lathes for compound machining, focusing on monitoring tolerance bands of key mating dimensions and surface roughness to meet precision assembly requirements.
