Deep Hole Drilling for Aircraft Structural Components
When Aircraft Structures Need Deep Holes Aircraft structural components like wing spars, bulkheads, and floor beams sometimes need through-holes for wiring harnesses, fluid lines, or fastener access. I have drilled these on CNC gun drilling machines with standard parameters. The holes are usually not structural themselves — they are pathways for systems that need to pass through the structure. But the parts they go through are highly stressed, so the drilling process cannot introduce stress risers or heat-affected zones. ...
