Precision CNC machining China aerospace engine titanium alloy blade custom manufacturing cnc machining china precision CNC machining

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.

1. 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.
2. 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.
3. 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.
4. Flexible Production Stability:
   • Dual-station machining enables batch production (e.g., 20 minutes for a 30mm blade). Online measurement and compensation ensure consistency.

• Civil Aviation: Blades for COMAC C919, offering weight reduction solutions (e.g., HuaTai RuiXiang’s annual capacity of 60,000 blades).
• Defense & Space: Military engine blades (e.g., 3200kgf-thrust fans), enhancing national security.
• Energy & Marine: Gas turbines and marine propulsion systems.

• Flexible Design: Custom 3D modeling and process planning, supported by trial cutting (e.g., "S" test specimens).
• Small to Large Batches: Automated feeding systems enable continuous production (e.g., NiuWei’s 100+ machine fleet).

• Technical Consulting: Optimization of cutting parameters and tool selection (e.g., CBN tools for high-speed machining).
• Real-Time Monitoring: Sensors track cutting force and temperature to prevent faults.
• After-Sales: 24/7 support for maintenance and process upgrades.
