When ?Global Defense Corp? needed 500 high-spec tactical charging handles with ±0.015mm tolerances and a durable matte anodized finish, they challenged us to deliver samples in 10 days. Here's how we achieved it:
CNC Precision & Process Control
• 5-Axis Machining: Processing 7075-T6 aluminum billets requires optimized tool paths for delicate thin-wall sections and intricate lever contours. This precision machining ensures structural integrity, minimizes waste, and eliminates stress points in tactical applications.
• First-Article Inspection: We use Coordinate Measuring Machine (CMM) to validate pivot hole diameter (Ø6.00±0.01mm), lever symmetry, and critical dimensions, ensuring all specifications meet design requirements.
• In-Process QC: Laser profilometry (0.02µm resolution) monitors surface finish (Ra 0.8µm) to ensure consistent micro-roughness—critical for wear resistance and smooth pivot operation. This eliminates stress points, meets aerospace-grade quality, and maintains 25±3µm anodizing thickness.
Quality Validation
•Dimensional accuracy: ±0.015mm (±0.01mm achievable)
•Surface hardness: =60 HRC post-treatment
•100% functional testing of pivot mechanisms
Result: Samples shipped in 8 days via DHL. The client confirmed:"Perfect fit with our AR-15 fixtures. The matte finish is consistent, and the levers operate smoothly."
A monthly order of 2,000 units was confirmed immediately.
