Airframe Gussets Components CNC Machining for Aerospace

Aluminum 2024-T3 has tensile strength of 470 Mpa, and damage resistance to failure safe gusset structures, high load path capability of 20000-60000 flight hours with multiple load paths, decent formability to complicated gusset shapes with flanges and shaped edges, and is also economical with high volume production. In weight critical reinforcements, Aluminum 7075-T6 is higher 572 MPa tensile strength that can support shear loads 5,000-50,000 N and has an excellent specific strength 204 kN /m /kg, excellent machinability with dimensional accuracy 5,000-0.50mm with a good fatigue behavior and low weight construction (density 2.81 g/cm 3 ). Titanium Ti-6Al-4V offers high temperature gusset specific strength ( 300 kN m/kg), tensile strength (900 MPa), fatigue, and low thermal expansion (8.6 m /m -1 K) to sustain dimensional stability -55 C +200 C, corrosion ability, eliminating protective layers in seawater, and embracability with composite structures to assure bonded hybrid joints.

Precision milling creates gusset plates with ±0.050mm dimensional accuracy across 100-800mm dimensions. Precision drilling creates fastener holes with ±0.040mm positional accuracy per MS/AN standards. Countersinking creates flush fastener interfaces per NASM specifications with depth tolerance ±0.050mm. Counterboring creates protruding head interfaces. Pocket milling creates weight-optimized structures with wall thickness 1.5-6mm reducing mass 10-25%. Edge preparation includes machined edge finish Ra 1.6-3.2μm and bonded surface preparation achieving Ra 0.8-1.6μm for composite interfaces per ASTM D2093. Precision machining creates stress-relief radii R 3-10mm at corners. Precision contouring creates formed edge profiles. Deburring per AS8049 eliminates stress concentrations. Heat treatment includes solution treatment for 2024 aluminum (T3 temper), solution treatment and aging for 7075 (T6 temper), solution treatment and aging for titanium.

We have dimensional accuracy within 0.50mm across gusset envelope 100-800mm with proper joint fit and structural alignment within machine tolerance 0.15mm with fastener holes, perpendicularity 0.50mm to mount faces, bonded surface finish 0.8-1.6mu with ASTM D2093, and R 3-10mm 2-3 many times the stress concentration factor. These tolerances accommodate shear loads between 1,000 and 50,000 N, shear strength between 150 and 500 Mpa, number of fasteners between 10 and 100 per gusset, joint efficiency of between 85 to 95 percent, safety factors between 1.5 and 2.0, fatigue life between 20,000 and 60,000 flight hours and FAA FAR Part 25 compliance as well as EASA CS-25.
