NAMF specializes in precision CNC machining and dip brazing of complex aerospace components. This aluminum housing subassembly highlighted here is used on an F-15E Strike Eagle. The body of the chassis is constructed of 6061 and 2003 aluminum alloys with 0.008” fin stock. The base of the chassis was machined on our precision CNC milling center. After machining, hardware and Heli-Coil inserts were installed and the assembly was dip brazed according to AWS-C3.7 Class C specifications. The cleaned assembly was coated with MIL-DTL-5541 Type II Class 3 chem film coating and painted with polyurethane paint per MIL-PRF-85285.
All engraving was performed with CNC machining equipment and filled in by hand with specialized ink, according to customer specifications. Lettering and graphics were stenciled and silkscreened onto the painted surface. The overall dimensions of the chassis are 15.570” x 12.631” x 7.527” with true dimension tolerances of 0.003”. Flatness tolerances were held to 0.01” with close work tolerances as tight as ±0.002”. Dimensional inspection was performed with precision CMM equipment. This aluminum alloy housing subassembly is an ongoing project for NAMF. For more information about this precision aerospace fabrication project, see the table below, or contact us directly.
