5-Axis CNC Machined Color Anodized Aluminum Bracket

Simultaneous 5-axis machining lets the cutter reach five faces and angled features from a single fixture, so hole patterns on different faces stay true to one datum. That matters on brackets where misalignment between mounting faces causes binding in the assembly. We program with short, rigid tools where possible and use 3+2 positioning for most features, switching to full simultaneous motion only for freeform surfaces.

6061-T6 is the economical, well-rounded choice and anodizes to bright, even colors. 7075-T6 offers roughly twice the yield strength and suits highly stressed arms and clamps, but it costs more and is less suitable for welding. Type II anodizing comes in black, red, blue, gold and other dyes; Type III hard anodize (typically 25–75 µm) is the option for wear surfaces, with a limited color range.

First articles receive a full CMM report covering angled hole positions and face perpendicularity. Production lots get in-process checks on every setup change and 100% inspection of critical dimensions. Color consistency is checked across the batch against a retained sample. Typical uses include sensor mounts, gimbal arms, camera rigs, robot end-effector plates and automation bracketry.
