Large Format CNC Machining for Aerospace Structures
Large envelope machining handles oversized aerospace structural components including wing spars, fuselage frames, and bulkheads. These machines feature extended travels of 60" or more and heavy-duty construction for accuracy at scale.
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
Materials Commonly Machined
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
