What key points should you consider when custom CNC machined aluminum brackets like integrated curved clamp supports?

✅ Material selection 6061-T6 for balanced machinability & anodizing finish; 7075-T6 for high-load clamping scenarios.

✅ Structural design Avoid sharp internal corners & thin-walled sections to prevent machining vibration and deformation. Leave proper radius transitions for curved surfaces. For external threads on soft aluminum, control overhang length to avoid thread stripping.

✅ 5-axis machining process Rough machining → stress relief → finish cut to minimize distortion on irregular curved profiles. Optimize toolpaths to eliminate visible tool marks for high-gloss surfaces. Thread milling is preferred for precise external threads.

✅ Surface finishing reminder If bright glossy appearance is required, choose decorative bright anodizing instead of hard anodizing. Mask threads before anodization to avoid assembly interference.
