Which machining process do you need?
When trying to source a machined part, instead of trying to specify the process for your part, let us take the hassle out of buying your machined parts. Roberts Automatics does CNC machining, CNC Turning, Swiss style turning and Multi-spindle screw machining.
Each machining process has a sweet spot and we utilize one or all of them to make your part economically and on time. So when you need a "CNC Machine shop near me", think about Roberts Automatics.
We know how to utilize the best of each machine to meet your strict total lowest cost goals. Other shops tend to make you fit their capabilities with an inflexible mindset... with 70 years in business, we allow our capabilities to fit you.
At Roberts, we have the attitude to work smarter and harder for you.
It's what you don't see that matters
attitude • passion • skill • expertise
We know how to choose the
right machine for the right part...
or any combination necessary for the total lowest cost parts
Our Mazak multi-tasking lathes allow us to machine complete complicated and tightly toleranced parts from bar stock or sawn slugs. Cross-drilling and tapping, milling, thread-milling and eccentric shapes can all be done in one sequence resulting in better efficiency and higher quality.
We can meet your needs for complex or simple parts with our wide range of multiple-spindle screw machines. We often hold tolerances on our screw machines that would require cnc machining or secondary operations saving you time and money.
CNC Swiss Type
Our Citizen and Tsugami Swiss style lathes machine parts from 4 MM to 32 MM diameter. Multi-tasking allows us to perform milling, cross-drilling, cross-tapping, off axis and eccentric machining all in one sequence allowing high precision, quality and productivity on complicated and tightly toleranced parts.
Our mastery of our machinery means you have more choices available... which contributes to giving you the best parts

Our Secondary Operations give us greater flexibility to deliver higher value added parts to our customers.
Established in 1947, Roberts Automatic Products is a third generation family-owned precision 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 that 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.
