Aerospace Machining & CNC Metal Lathe High Precision Turned Parts for Aviation & Defense
Aerospace engineers and procurement specialists — when you need high‑reliability turned components that meet AS9100 standards, our aerospace machining service powered by precision CNC metal lathes delivers ±0.002mm tolerances on titanium, Inconel, and other aviation alloys. With 15+ years of dedicated aerospace experience, we have completed over 8,000 projects with a 99.8% quality rate and 99.4% on‑time delivery.
✈️ Professional Aerospace Machining – Built for Extreme Conditions
Our aerospace machining service is tailored for components that must withstand extreme temperatures, high pressure, and long‑term fatigue. We specialize in rotational parts (shafts, bushings, fasteners, turbine accessories) that constitute over 60% of aerospace structural components.
🎯 Aerospace Machining Highlights
- Tolerances: ±0.002mm – ±0.01mm
- Surface finish: Ra < 0.2μm (mirror on critical seals)
- Materials: Titanium (Gr5), Inconel 718, 6061/7075 Al, 304/316 SS, brass
- Certifications: AS9100D, ISO 9001, IATF 16949 (where applicable)
⚙️ Typical Aerospace Parts
- Engine shafts & micro shafts
- Locking fasteners & threaded bushings
- Landing gear small components
- UAV structural parts & spacecraft connectors
Our process includes DFM optimization to avoid material waste and deformation common in hard‑to‑cut alloys. We support prototype verification, small‑batch trial, and large‑scale production with consistent quality.
🔧 High‑Precision CNC Metal Lathe – Core Process for Aerospace Rotational Parts
We operate 15+ high‑precision CNC metal lathes, including Swiss‑type and horizontal lathes from leading brands. These machines are specially calibrated for aerospace alloys, featuring high‑speed stable rotation, low vibration, and micron‑level dimensional control. Capabilities:
- Diameter range: 0.5mm – 300mm (customizable)
- Length up to 800mm (longer parts on request)
- Surface finish down to Ra 0.2μm
- Thread cutting (internal/external) and live tooling for milled features
For titanium, we use low cutting speeds and high‑pressure coolant to prevent work hardening. Each batch undergoes 100% inspection with CMM and optical comparators.
🔄 Integrated Aerospace Machining – One Supplier, Complete Confidence
Many aerospace buyers struggle with fragmented supply chains: turned parts from one vendor, milled parts from another. We combine CNC metal lathe (rotational) with 5‑axis milling under one roof, ensuring consistent quality standards and single‑source accountability. All parts follow the same AS9100 quality management system, with full material traceability and inspection reports.
