Custom CNC Machined Precision Shaft Sleeves, Flange Locating Pins, and Irregular Hardware

As core connection units for fluid control loops or mechanical transmission systems, this kit includes multi-step shaft sleeves, flanges with mounting holes, and internal/external thread conversion joints. These rotational structures are commonly used for guide support in automation equipment, fine-tuning locking in valve actuators, or rigid fixation of sensor mounts, ensuring axial positioning accuracy and connection reliability under vibration through precise fitting.

The manufacturing process relies on combined CNC turning and milling, focusing on controlling the straightness of slender rods, high coaxiality between flange ends and inner bores, and thread regularity to prevent wobbling, jamming, or sealing failures during assembly. Cutting parameters are optimized for different base materials such as stainless steel, brass, and aluminum alloys to suppress deformation and eliminate burrs, while strictly controlling the surface finish of key mating surfaces to meet assembly requirements in clean environments.

Equipped with high-precision CNC lathes, machining centers, and CMMs, we support custom non-standard manufacturing based on 2D/3D drawings, including material selection, thread standards (e.g., Metric M, Imperial G/NPT), and surface treatments. Adhering to the ISO 9001 quality management system, our production process covers material traceability, go/no-go gauge testing, and 100% visual inspection. We provide material certificates and key dimension inspection reports to ensure that batch-delivered products meet the stringent standards of the petrochemical, medical device, and high-end equipment manufacturing industries in terms of fit precision and consistency.
