CNC Precision Flange Bushing Assembly

As critical connection nodes in mechanical transmission systems and fluid pipelines, these disc-shaped and cylindrical structures with central through-holes and peripheral mounting holes are primarily used for radial support, positioning guidance of rotating shafts, or rigid docking between different components. The main body features a rotational geometry, with some configurations including internal threaded interfaces or lateral split slots. Secure assembly in automation equipment modules, instrument shafts, and tooling fixtures is ensured through bolt fastening or clamping, effectively preventing axial displacement or circumferential slippage during high-speed operation.

The core of the manufacturing process lies in ensuring strict coaxality of multiple outer diameters relative to the central axis, as well as the flatness tolerance of the end mounting surfaces, to prevent skewing or uneven stress distribution after assembly. For parts with multi-step profiles, side threaded holes, and complex internal cavities, positional and perpendicularity tolerances between features must be strictly controlled. Due to the multi-process transitions involving turning outer circles, milling planes, drilling, and tapping, high-rigidity CNC machining centers combined with CNC lathes are typically used for composite machining. Key monitoring points include thread profile accuracy and surface roughness of mating surfaces to ensure connection reliability and sealing performance.
