Excellence in Production, Excellence in Service
Founded in 1946, Orrco has been at the forefront of the CNC and screw machine industry for over 75 years. Our story began in a small Pittsburgh garage shop, where Tom Orr established a screw machine operation that quickly gained a reputation for reliability and quality. By 1951, Orrco had moved to its current location in Greensburg, PA, and over the years, we have expanded our facilities to 45,000 square feet, equipped with state-of-the-art CNC Mill-Turn index machines and custom-built machining centers.
Our commitment to precision, craftsmanship, and customer satisfaction has remained unwavering throughout our history. We have proudly served various industries, from military applications and mining to valve production and cutting-edge communications systems.
