Why Aerospace Requires Precision Turning

  • ✓Critical for rotating components in engines and actuators
  • ✓Tight concentricity requirements for balance
  • ✓Surface finish critical for seal interfaces
  • ✓Thread accuracy for fasteners and fittings
  • ✓ID/OD relationships crucial for assembly

Typical Applications

→Engine shafts and spindles
→Actuator housings
→Hydraulic fittings
→Fasteners and studs
→Valve bodies
→Landing gear components

Materials Commonly Machined

Titanium alloysStainless steelsAluminum alloysInconelTool steelsBeryllium copper

Technical Considerations

  • •Live tooling enables milling operations in turning setup
  • •Sub-spindle capability for complete parts
  • •Bar feeders for high-volume production
  • •In-process gauging for tight tolerance work
