Copper Alloy Multi-Step Precision Bushing

As a critical transition component in mechanical transmission systems, this series is primarily used to achieve rigid connection and positioning between rotating shafts and actuators. The structure includes cylindrical sleeves with lateral locking threads, irregular joints with flanged lugs, and stepped copper bushings, designed to fit compact installation spaces within various equipment.

These parts have strict requirements for coaxiality and surface finish of mating surfaces. In particular, the dimensional tolerances of inner bores and outer diameters must be controlled at the micron level to ensure smooth assembly. For features such as stepped shafts, eccentric holes, and side tapping shown in the images, high-precision turning or turn-mill composite processes are employed to ensure one-time clamping formation. This avoids cumulative errors from multiple setups while meeting inspection standards for thread fullness and mounting surface perpendicularity.

Our factory is equipped with Swiss-type automatic lathes and CNC lathes from brands like Tsugami and Star, capable of precision machining materials including stainless steel, carbon steel, and copper alloys. We hold IATF 16949 and ISO 9001 quality system certifications and are equipped with Vickers/Rockwell hardness testers and metallographic microscopes for comprehensive material performance verification and dimensional control. Upon receiving detailed engineering drawings, we will evaluate specific manufacturing solutions and lead times based on material grades, surface treatment requirements, and batch sizes.
