1. Industry Challenges & Solutions
|
|
Critical Challenges in Mg-Li Alloy Machining• Structural Deformation: 0.3-0.5mm thin walls prone to vibration-induced warping • Fire Hazards: Combustible machining dust (ignition point < 450°C) • Surface Degradation: Rapid oxidation reduces coating adhesion by 30-50% |
Our Proprietary Solution✓ Inert Gas-Shielded Machining System: Argon environment prevents combustion and oxidation ✓ AI-Powered Stress Simulation: Predicts deformation points with <0.05mm accuracy ✓ Real-Time Process Monitoring: 12-axis vibration compensation for ultra-thin structures |
