Precision Machined Metal Bushings and Connectors

We provide CNC turning and milling services for custom non-standard metal bushings, locating pins, and special-shaped connectors, catering to the automotive interior frameworks, rail transit, and agricultural machinery sectors. For complex rotational structures, eccentric holes, and multi-step mating surfaces as shown, we utilize Swiss-type lathes or turn-mill compound machining for integrated forming. This effectively ensures coaxiality and positional tolerances, meeting high-rigidity assembly requirements.

The machining process strictly adheres to the datum system defined in drawings, with a focus on controlling outer diameter, inner hole tolerance zones, and end-face perpendicularity. For thin-walled tubular structures or slender rods, we optimize clamping solutions to prevent deformation. For copper or aluminum parts, our factory-equipped ultrasonic cleaning lines remove machining residues, ensuring burr-free, clean surfaces that comply with RoHS and REACH environmental standards.

Jiangsu Xinyunuo New Energy holds both IATF 16949 and ISO 9001 certifications. We are equipped with high-precision machinery, including Jiecheng and Tsugami Swiss-type lathes and Guangdong Yiji turn-mill compound centers, supporting stable delivery from prototyping to mass production. Quotations are based on specific 3D models or 2D engineering drawings, clarifying material grades (e.g., brass, aluminum, stainless steel), surface treatments (anodizing, plating, etc.), and key dimensional tolerance levels.
