Precision CNC Machining Aluminum Parts

FlexiTurn provides precision 5-axis CNC machining services for custom aluminum structural pivot brackets, including this lightweight twin-plate clevis bracket engineered for articulated load bearing, structural mounting and precision alignment in aerospace, robotic and automotive systems.

This high-strength aluminum clevis features a double-arm design with lightening cutouts, precision coaxial pivot bores, and multi-directional mounting faces. The part requires tight bore coaxiality, consistent geometric alignment, and long-term fatigue resistance to withstand dynamic loading and vibration in service.

5-Axis CNC Milling Capabilities

• Complex Contour & Cavity Milling: 5-axis simultaneous machining delivers continuous tool access to multi-sided profiles and internal recesses, reducing setups and maintaining consistent wall thickness across lightening features.
• Precision Pivot Bore Machining: Cross-bore drilling and precision reaming produce coaxial mating bores with controlled surface finish and diameter tolerance for reliable articulated assembly.
• High-Strength Aluminum Process Calibration: Spindle speeds, feed rates and carbide tool geometries are fine-tuned for 7075 aluminum to control machining-induced surface work hardening, suppress tool chatter and deliver uniform surface finish.
• Minimal-Setup Fixturing Strategy: Optimized workholding and indexing methods minimize clamping operations, reducing cumulative alignment error while maintaining full access to all critical features.
