Deep Hole Gun Drilling for Aerospace & Defense
Gun drilling creates deep, straight holes with exceptional straightness and surface finish. Critical for aerospace hydraulic components, landing gear, and fuel system parts requiring holes with length-to-diameter ratios exceeding 20:1.
Why Aerospace Requires Gun Drilling
- ✓Landing gear require deep, precise bores
- ✓Hydraulic systems need straight fluid passages
- ✓Fuel system tubes require consistent ID
- ✓Actuator bodies have deep internal features
- ✓Cannot be achieved with standard drilling
Typical Applications
Materials Commonly Machined
Technical Considerations
- •Depths up to 100x diameter possible
- •High-pressure coolant through tool (1000+ PSI)
- •Single-flute drill with guide pad
- •BTA system for larger diameters
