Our Story
Who We Are: OTTR
At OTTR Machining & Engineering, we are more than just a machine shop—we are a veteran-owned team of experienced machinists, engineers, and problem solvers committed to precision, innovation, and excellence. Based in Oklahoma, we provide custom CNC machining, reverse engineering, and full-scale production services for aerospace, defense, automotive, and industrial applications.
We started OTTR because we experienced firsthand the challenges of getting high-quality custom parts manufactured—slow lead times, complex processes, and high costs. Instead of relying on outdated methods, we built a streamlined approach that delivers instant quotes, fast turnaround times, and unmatched reliability. Today, we are helping businesses across the U.S. bring their designs to life with precision-crafted solutions made right here in Oklahoma.
At OTTR, we recognize that Oklahoma’s future in advanced manufacturing, aerospace, and defense depends on having a strong, highly skilled workforce. The demand for precision machining, engineering, and technical expertise is growing faster than the availability of trained workers, creating a critical skills gap that threatens the industry’s ability to expand.
As a veteran-owned company, we are committed to closing this gap and strengthening Oklahoma’s workforce by:
Investing in hands-on training programs – We work with trade schools, community colleges, and workforce development initiatives to provide real-world experience in CNC machining, CAD/CAM programming, and advanced manufacturing techniques.
Creating career pathways for skilled workers – Through on-the-job training, apprenticeships, and mentorship programs, we equip workers with the skills needed to thrive in high-demand manufacturing careers.
Supporting veteran career transitions – As a team of military veterans, we actively hire and train fellow veterans, helping them transition into engineering, machining, and manufacturing roles that leverage their technical and leadership skills.
Oklahoma has long been a hub for oil and gas, aerospace, defense, and industrial manufacturing, but to maintain that leadership, we must prioritize workforce development and ensure that local talent is prepared for the future of precision machining.
By investing in people, technology, and partnerships, OTTR ensures that Oklahoma remains a leader in precision manufacturing and innovation for years.
