At Ridge Engineering we specialize in tight tolerance precision CNC machining, the project highlighted here exemplifies our commitment to quality and precision. This item was designed for use as a fitting on a space craft. Machined from 7″ thick solid billet, 6AL-4V titanium, it was manufactured to Mil-spec MIL-STD-1547B.

Manufacturing utilized our state of the art DMC douBLOCK® True 5 axis milling center, this allowed us to meet the required tolerances of ±0.0005″. The finished component measured 6.5″ in length, 3.25″ in width, and 3.75″ in height, and was finished with a yellow BR127 primer, and featured a surface roughness of 32 RMS. We manufactured less than 100 of these components with a lead time of 4 weeks. To learn more about this precision CNC milled project, see the table below or contact us directly.
