CNC machining of aerospace components

CNC machining of aerospace components for precision

We provide high‑precision CNC machining services for the aerospace sector, manufacturing flight‑critical and high‑reliability parts such as aircraft structural components, engine parts, fuel and hydraulic system assemblies, sensor housings, and critical components for satellites and spacecraft.

Description

We ensure parts meet stringent dimensional, geometric, and surface quality requirements through strict process control, temperature-controlled workshops, precision fixturing, and stable tooling systems.

CNC machining capabilities and equipment:

  1. Main equipment: 5‑axis machining centers, vertical and horizontal CNC machining centers, CNC lathes, turn‑mill multitasking centers, CNC boring‑milling machines, and large gantry machining centers, supported by precision measurement and online compensation systems.
  2. Machining capabilities: support multi‑face machining in a single setup, high‑precision 5‑axis compound machining, micro‑cutting and fine finishing, deep hole machining and high‑precision drilling/boring of small holes. Stable machining of complex surfaces, thin‑wall structures and asymmetric parts can be achieved.
  3. Control points: temperature‑controlled machining environment, tool compensation, dynamic balancing of workpieces, rigid fixturing and vibration suppression design to ensure machining consistency and batch stability.

Material support and blank forms for aerospace components:

  1. Supported materials: aerospace aluminum alloys (e.g., 7075, 2024), titanium alloys (e.g., Ti‑6Al‑4V), nickel‑base alloys (e.g., Inconel series), high‑strength stainless steels, aluminum‑lithium alloys and high‑performance engineering plastics.
  2. Blank forms: bar stock, milled/forged blanks, cast blanks or customer‑supplied blanks; recommendations for blank shapes and heat‑treatment conditions can be provided based on material and part structure to reduce machining difficulty and cost.

Surface treatments and secondary operations:

  1. Standard and specialized surface treatments: anodizing, electroless plating, hard anodizing, phosphating, electrophoretic coating, corrosion‑resistant coatings, nickel plating, metal plating and electrochemical polishing, etc. Surface treatment solutions suitable for titanium and nickel‑base alloys are available.
  2. Strengthening processes: heat treatment, aging treatment, surface nitriding or carburizing (depending on material), shot peening to improve surface fatigue life and crack resistance.
  3. Assembly and testing: we can provide part pre‑assembly, functional testing, air and liquid tightness tests, and cleanliness processing (cleaning and packaging that meet aerospace requirements).

Quality control and certification support:

  1. Inspection process: incoming inspection, first article inspection (FAI), in‑process inspections, final inspection and pre‑shipment inspection to establish a complete production traceability chain. AS9102‑type FAI requirements can be executed per customer request.
  2. Inspection equipment: coordinate measuring machines (CMM), surface roughness testers, profile/optical projectors, roundness and concentricity measuring instruments, hardness testers and dedicated fixture gauges.
  3. Certificates and documentation: material test reports (MTR), inspection reports, FAI reports, heat‑treatment and surface‑treatment records can be provided. We can support ISO, AS, PPAP and other system certifications or supply‑chain compliance documents per customer requirements.
