Custom CNC Milled Bronze Mounting Brackets

This U-shaped bronze mounting bracket demonstrates FlexiTurn’s precision CNC milling capabilities for prismatic copper alloy components. Key engineering challenges—including pocket parallelism, tight-tolerance side-hole tapping, flange flatness, and cross-feature alignment—are resolved through optimized 3-axis and 4-axis machining strategies. FlexiTurn supplies custom, burr-free structural components engineered for direct assembly integration.

Precision Milling & Processing Capabilities

• Multi-Axis Process Routing: 3-axis and 4-axis CNC milling platforms execute flange face milling, deep U-pocket profiling, perimeter trimming, and corner chamfering in minimized setups, preventing cumulative positional error.
• Precision Drilling & Tapping: Side-tapped holes and mounting through-holes are drilled and threaded with strict true-position control, ensuring thread engagement and bolt-pattern alignment during final assembly.
• Burr & Surface Management: Calibrated cutting feeds and speeds leverage bronze’s machinability to deliver crisp feature definition and uniform surface finishes directly from the machine, eliminating manual deburring defects.
• Optional Precision Grinding: Available for critical mating or sealing interfaces requiring enhanced flange flatness (≤ 0.005 mm) and refined surface finishes.
