Custom 5 Axis CNC Machining 2A12-T4 Aluminum Alloy Flange, Precision Mechanical Parts

This precision aluminum flange is a functional mechanical interface component designed for equipment connection, structural support and precision assembly. Manufactured from 2A12-T4 aluminum alloy, the part combines low weight with good mechanical strength and dimensional stability. The flange features multiple concentric surfaces, distributed mounting holes, threaded holes and a central recessed structure, requiring accurate control of hole positioning, flatness and concentricity during machining.

Using 5-axis CNC machining, complex features can be accurately produced while minimizing multiple setups and cumulative positioning errors. The machined surfaces provide a precise fit with mating components and maintain consistent performance during assembly. We support custom machining based on STEP/IGES files, technical drawings or physical samples. Material options including 2A12, 6061 and 7075 aluminum alloy are available, along with anodizing and other surface treatments. Material certificates, dimensional inspection reports and CMM inspection reports can be supplied for applications requiring high precision, stability and repeatability.
