Wordingham Technologies manufactured a four-component opto-mechanical aluminum fisheye housing assembly in a projection application. Using CNC turning on a 6061-T6 aluminum base material, pieces of varying diameter and thread are manufactured. The outside diameter of the largest piece measures 6.313″ across, and thread size and pitch range from 5.469-32 UNC-2B to 2.406-32 UNC 2B. All manufacturing processes on this piece maintain a tolerance of ±.0005″, with a circular runout of ±.0005″ and a perpendicularity of ± .0005″. Maintaining proper tolerance is important, as the housing pilot must fit so that it can be assembled and disassembled as needed.
After CNC turning is completed, pieces are finished with a black anodized layer and a surface finish of 16 RMS and assembled, with an overall final length of 24.059″. We work from a customer-supplied print and perform in-process testing and quality control requirements determined by the Quality Supervisor. This aluminum fisheye housing assembly is an excellent example of our CNC turning, custom optics machining, and assembly expertise.
