Precision CNC Machining for Aerospace Engine Titanium Alloy Blades
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.
Key Features
High-Precision Complex Surface Machining
5-axis CNC machining achieves profile tolerances of -0.12~+0.03mm and edge tolerances of ±0.05mm. Optimized tool paths (e.g., spiral entry) minimize idle time.
Superior Material Performance
TC11/TC6 titanium alloys offer high strength and heat resistance (up to 650°C), reducing blade weight by 50% and engine weight by 30-60kg. Laser-assisted or cryogenic cooling machining enhances tool life.
Surface Integrity Enhancement
Ultrasonic Surface Rolling Processing (USRP) with contour-matched pads controls deformation (<0.07mm error), achieving Ra <0.4μm and compressive residual stress for improved fatigue resistance.
Flexible Production Stability
Dual-station machining enables batch production (e.g., 20 minutes for a 30mm blade). Online measurement and compensation ensure consistency.
