Precision CNC Machining for Aircraft Structures
Aircraft structural components carry flight loads, resist fatigue, and define the shape of the airframe. A wing rib with pockets 0.003" too deep or a bulkhead with mislocated fastener holes creates a reject — or worse. We machine 7075-T6, 2024-T3, and titanium 6Al-4V structural parts with wall thicknesses as thin as 0.040", pocket depths to 3 inches, and fastener hole patterns held to ±0.001" true position. Every part ships with CMM inspection and material certs.
Deep Pocket Expertise
Wing ribs and bulkheads often require 90%+ material removal. We use high-speed roughing strategies, sharp carbide tooling, and optimized stepdowns to hold tight wall thicknesses without chatter.
Distortion Control
Large aluminum plates warp when you remove most of the material. We flip parts, alternate roughing sides, and use stress-relief passes to keep flatness within spec on every structural component.
Fastener Hole Precision
Structural parts carry hundreds of fastener holes. We hold ±0.001" true position on every hole pattern so your assembly team doesn't fight fit issues on the shop floor.
Aircraft Structural Components
Wing ribs, fuselage frames, bulkheads, spars, longerons, and skin panels.
Wing Ribs
CNC-machined wing ribs from 7075-T6 aluminum plate. Deep pockets with 0.040" minimum wall thickness, lightening holes, stiffener flanges, and fastener hole patterns held to ±0.001" true position. Typical material removal ratios exceed 90%.
Al 7075-T6 | Deep pocketsFuselage Frames
Fuselage frame sections machined from 2024-T3 and 7075-T6 aluminum. C-channel and Z-section profiles with precise web thicknesses, cap widths, and shear tie attachment holes. Flatness held to 0.002" over 24 inches.
Al 2024-T3 | Thin websBulkheads
Pressure bulkheads and structural bulkheads machined from thick aluminum plate. Complex pocket patterns, integral stiffeners, and close-tolerance bore holes for hinge pins and actuator attachments. CMM verified on every critical feature.
±0.001" boresSpars
Wing spars and carry-through structures machined from 7075-T6 and 7050-T7451 aluminum plate. I-beam and C-channel profiles with precise cap thicknesses, web tapers, and attachment fittings machined in a single setup.
7050-T7451 | Single setupLongerons
Fuselage longerons and stringers machined from extruded or plate aluminum. Long, slender parts requiring precise straightness, consistent cross-sections, and pilot holes for rivets spaced at exact intervals along the length.
Straightness criticalSkin Panel Stiffeners
Hat-section and Z-section skin stiffeners machined from 2024-T3 aluminum sheet and plate. Precise flange angles, consistent thickness profiles, and rivet hole patterns that align perfectly with fuselage frames and longerons.

Every commercial and military aircraft relies on thousands of precision-machined structural components. Wing ribs alone can number over 40 per wing, each one unique in shape and pocket depth.
The demand for structural machining is driven by new aircraft programs, fleet expansions, and the constant need for replacement parts on aging platforms. Tier 1 and Tier 2 suppliers need reliable machining partners who can hold tight tolerances, deliver full documentation, and keep up with production schedules.
Whether you're building parts for a new single-aisle program or supplying replacement ribs for legacy military aircraft, we machine structural components with the precision and traceability your program requires.
Boeing 737 / 787 Programs
The 737 and 787 programs consume tens of thousands of unique structural parts. Wing ribs, fuselage frames, floor beams, and door surrounds all require precision CNC machining from aerospace-grade aluminum.
Lockheed Martin F-35 Lightning II
The F-35 airframe uses machined aluminum and titanium structural components throughout. Bulkheads, wing carry-through structures, and fuselage frames are all CNC machined to tight tolerances.
Airbus A320 / A350 Family
Airbus programs source structural components from suppliers worldwide. Wing ribs, spar fittings, and fuselage frame segments are machined from 7075, 7050, and 2024 aluminum alloys.
Spirit AeroSystems — Aerostructures
As the world's largest aerostructures manufacturer, Spirit builds fuselages, nacelles, and wing components. Their supply chain depends on hundreds of machine shops for structural detail parts.
Built for Structural Machining
Deep pockets, thin walls, and tight fastener patterns demand a shop that understands airframe work.
High-Speed Pocket Machining
Wing ribs and bulkheads require removing 90%+ of the raw material. We use trochoidal roughing, optimized stepdowns, and sharp carbide tooling to machine deep pockets without chatter or tool deflection.
Warpage Prevention
We rough both sides, alternate passes, and use stress-relief skim cuts to prevent warping on large structural parts. Your bulkhead arrives flat — not bowed from residual stress.
Fastener Pattern Accuracy
Structural parts carry hundreds of rivets and bolts. We hold ±0.001" true position on every fastener hole so your assembly team gets perfect fit-up every time.
