About Orrco
Precision. Reliability. Built to Last.
Since 1946, ORRCO has delivered high quality precision machining with a commitment to craftsmanship, consistency, and customer trust. What began as a small screw machine shop in a Pittsburgh garage has grown into a 45,000 square foot facility in Greensburg, PA, equipped with advanced CNC Mill-Turn Index machines and custom built machining centers.
Founded by Tom Orr after World War II, ORRCO quickly earned a reputation for reliability that set us apart. Today, we continue that legacy with a team of skilled professionals and a full suite of machining capabilities and secondary processes that meet the demands of industries ranging from motion control to medical manufacturing.
We’re built for precision—and trusted for it. Whether you’re looking for tight tolerances, fast turnaround, or a supplier who understands the value of partnership, ORRCO is ready to deliver.
From military applications to the mining industry, from valve production to 21st century communications systems, Orrco has proven its value to generations of engineers and successful businesses.
Using only quality raw materials, our talented and experienced production teams fabricate superior quality products from aluminum, steel, brass, stainless steel, plastic, and copper.
