Large Sheet Metal Assembly Machining for Commercial Aircraft

Our team at Clearwater Engineering was awarded this custom sheet metal assembly project by a customer in the commercial aircraft industry. With an ever growing facility that is comprised of advanced machining and fabrication equipment, we are capable of handling a variety of aluminum and hard metal projects for the aerospace industry, including fracture and maintenance critical parts.

The part shown here is an upper rack assembly formed from 6061-T651 aluminum sheet. The assembly is formed according to applicable Boeing fabrication specifications, holding tolerances as tight as ±0.015", and is assembled in-house. In addition to machining and fabrication, we provide precision assembly of aircraft components and can coordinate any secondary operations as needed.

A chromic acid rinse is used to clean and protect the assembly prior to masking and application of FR Prime to the designated areas. Nondestructive testing is performed to verify conformance to all customer specifications and industry standards. We produce 24 of these assemblies annually with a turnaround time of one month.
