Precision Shaft Machining for Aerospace: Meeting the Demands of Altitude, Speed, and Complexity
✈️ Precision Shaft Machining for Aerospace: Meeting the Demands of Altitude, Speed, and Complexity 🌍
In aerospace manufacturing, there’s no room for error.
From engine turbines to wing flap shafts, every component must withstand extreme temperatures, vibration, pressure, and flight-critical conditions. And when it comes to shaft components, we know — even a micron makes a mission-critical difference.
🛠 What We Do:
As a China-based precision CNC machining factory, we specialize in high-complexity, custom shaft components for global aerospace OEMs and Tier 1 suppliers.
📐 Drawing-to-Part Customization
🔥 Titanium / Inconel / Stainless Steel / Aluminum Alloys
🎯 Tolerance: ≤0.002 mm | Surface Finish: Ra 0.02 µm
🔧 Equipment-Driven Process Control
- Mazak CNC lathes: For rough machining of non-round, thin-wall blanks
- Mikron high-speed CNC mills: For intricate profiles and multi-axes contours
- Studer precision grinders: Bore + OD grinding to <2µm tolerance
- Tokyo Precision roundness meter + Zeiss CMM: 100% dimensional control
👉 All processes verified by on-line inspection & final inspection reports provided.
🛰 Notable Aerospace Applications & Cases
1️⃣ Titanium Turbine Shaft for Jet Engine (EU Aerospace Tier 1)
