Established in 1947, Roberts Automatic Products is a third generation family-owned precision production machining company. Since our inception we have been dedicated to providing the highest levels of production quality, service, and productivity. We specialize in precise and complex CNC machining and screw machine parts along with extensive secondary operations and assembly.

Our company machines a wide variety of materials including stainless steel, carbon steel, aluminum, brass, bronze, copper, tool steel, titanium, Nylon, Ni-Span-C, Kovar, Inconel, Delrin, and Teflon. We also machine MIM blanks, and castings.

At Roberts our goal is 100% on time performance. We support your delivery schedule including JIT, Kan-Ban, blanket orders, and build-to-ship.

Our broad range of screw machine equipment and CNC machining capabilities allow us to run complex parts with tight tolerances. We are able to run parts on our screw machines that others must take exception to. We machine stainless steel, brass and aluminum on our Davenports, Acme-Gridleys, Gildemeisters and Euroturn machines. Secondary operations are often eliminated and costs reduced because we can hold tight tolerances and use attachments to complete parts.


Quality is the basis of our manufacturing philosophy. Quality is ensured because it is planned into the production process and supported by our Micronite SPC system, Zeiss CMM, Oasis Vision system, optical comparators and electronic and standard gauges. Roberts is ISO 9001 : 2008.

In-house tooling capabilities including wire EDM and 5-axis tool grinding allow us to respond efficiently and creatively to customer requirements without the added delay and costs of relying on outside vendors.

Extensive secondary operations including broaching, thread rolling, multi-hole drilling and tapping, mills, lathes, and custom-built multiple function machines contribute to our ability to add value.

Successfully providing high quality parts on time has earned us the ability to be a valued supplier to a broad range of markets including defense, medical, aerospace, process control, filtration, industrial, telecommunications and precision molding.
