Custom Fabrication of Aluminum Core Vane Assembly


A leader in manufacturing complex assemblies and components for the Aerospace industry, Birken Manufacturing has been contracted to fabricate aluminum core vane assemblies.  These aircraft engine components are produced based on customer provided CAD drawings. We CNC milled and CNC turned aluminum to fabricate the details as well as fabricate 54 vanes. Prior to dip brazing, we dry fit the assembly to ensure that the gap between the vane, inner case, and outer case is correct. To achieve a smooth finish, we deburred the component before anodizing. The part number was marked by using vibro-peen marking. The core vane assembly has an outer diameter of 26", inner diameter of 14", and a true position of .003". We performed dimensional, CMM, visual and fluorescent penetrant inspections before delivering the final product to the customer.
