CNC Machined Illuminated Dial and Pointer Assembly for the Aerospace Industry

The illuminated dial and pointer assembly shown here was designed to indicate flap positions for a commercial aircraft application.

This product demonstrates our ability to produce precision illuminated dial and pointer assemblies. The illuminated dial also contains threaded brass inserts which allow for installation into the final assembly. Each pointer shaft is torque-tested and 100% straightened, and the face of the dial and pointers are toned to ensure uniform brightness (foot-lamberts) for all the graphics.

Manufacturing required the use of precision CNC milling and turning, liquid honing, sand blasting, deburring, and annealing. Spray painting and pad printing were also applied and utilized plotter cut spray masks. Parts were also laser etched utilizing our Ytterbium Fiber Laser. The finished component measured 1.785" in diameter and 0.607" thick, and met tolerances of + 0.000"/ - 0.001", and + 0.001"/ - 0.000".

The sheer number of required materials and standards that had to be met to manufacture this component demonstrates our ability to provide precision fabrication service for the most complex components. For more information on this project, see the table below or contact us directly.
