Precision Copper Multi-Step Connector Shaft

Functioning as a conductive or mechanical transition element, this stepped shaft features distinct diameter changes to facilitate precise axial positioning and secure mating within assemblies. The central raised collar serves as a stop face or support surface, while the smooth cylindrical ends are engineered for insertion into corresponding bores or sleeves, ensuring stable alignment in rotating or static applications.

Manufacturing requires strict control over the concentricity of the multiple outer diameters and the perpendicularity of the shoulder faces to prevent assembly interference or uneven wear. Surface finish on the mating sections is critical to minimize friction and maintain consistent electrical contact or sealing performance. Utilizing CNC turning or Swiss-type machining allows for single-setup production, effectively managing tolerance stacks and ensuring uniform geometry across the length of the part.

Changzhou Aofeng Plastic & Mould Co., Ltd. supports the fabrication of such precision metal components with IATF16949 and ISO 9001 certified quality systems. Equipped with high-precision turning centers and inspection tools like profile projectors and hardness testers, the facility ensures dimensional accuracy and material integrity. Please provide detailed drawings specifying material grade (e.g., brass, bronze, or copper), tolerance limits, and any required surface treatments to receive an accurate evaluation for lead time and cost.
