Over the past three years Birken Manufacturing has invested over 3.5 million dollars into our precision CNC machining facility. This has allowed us to offer expanded services to our customers in the military, commercial, and general aviation industries. Birken's precision CNC machining capabilities and design services can be applied to a variety of jet engine components. The fabrication of products ranging from gear boxes to air foils can be completed at our Bloomfield, Connecticut facility.

Our precision CNC equipment allows us to work with part diameters of up to 50", lengths of up to 60", widths of up to 40", and heights of up to 32", with a maximum weight of 100 lbs. We can deliver extremely tight tolerances including: flatness to ±.000002", diameter roundness to ±.00005" and diameter cylindricity of ± .0001".

Specializing in metals such as aluminum, steel, and titanium, we are also adept at working with nickel, magnesium, and other exotic alloys. We also have the capability to manufacture from various raw material types including bar stock, castings, forgings, and sheet metal. Secondary services include assembly, welding (fusion/resistance), fabrication, epoxy painting, cleaning, hot forming, and EDM. We offer fluorescent penetrant and magnetic particle inspection and have several coordinate measuring machines for detailed inspection.

While working with our customers, we develop prototypes that lead to volume production runs.

For more detail on our precision CNC machining services, EDM and weld capabilities, please see the various services below and contact us directly to learn more about our capabilities.
