Aero-engine blades are core components determining engine performance and reliability. We specialize in high-precision CNC machining of titanium alloy blades, utilizing 5-axis CNC machines and advanced processes to ensure stability under extreme temperatures and pressures. These blades feature thin-walled complex geometries (e.g., leading/trailing edge thickness as low as 0.2mm), high twist angles (up to 80°), and require tight tolerances (±0.05mm) and surface roughness (Ra ≤0.4μm). Our "near-net forging + precision CNC machining" approach controls microstructural properties and enables specialized surface treatments, filling technological gaps in large-scale wide-chord titanium blade manufacturing in China.
