Why Aerospace Requires Large Envelope Machining

  • ✓Aircraft structures require large monolithic parts
  • ✓Reduces assembly complexity and weight
  • ✓Single-piece machining improves structural integrity
  • ✓Critical for wing spars and fuselage sections
  • ✓Enables machining of unitized structures

Typical Applications

→Wing spars and ribs
→Fuselage frames and bulkheads
→Floor beams
→Door surrounds
→Nacelle components
→Cargo door structures

Materials Commonly Machined

Aluminum 7075-T651Aluminum 2024-T351TitaniumSteel

Technical Considerations

  • •Machine travels typically 60" to 300"+ in X axis
  • •Floor-type or gantry configurations common
  • •Temperature compensation for thermal growth
  • •Heavy pallet systems for workholding
