Triangle Machine Products delivers precision CNC turning services for manufacturers that require custom CNC turning and tight tolerance parts in demanding industrial applications. As a U.S.-based CNC turning company established in 1957 and headquartered in Cleveland, Ohio, we support OEMs and Tier suppliers with precision CNC turning machining for pins, shafts, hubs, fittings, couplings, bushings, and other critical components.
Our CNC precision turning capabilities are built around high-speed production efficiency, dimensional, and process control. Whether your application requires close concentricity, tight tolerances, critical surface finishes, or secondary machining operations, our team provides precision CNC turning services to meet and exceed all customer expectations.
Our CNC turning services support everything from prototype development to high volume production runs. With over 30 automatic screw machines and CNC turning machines, we offer capacity for all production requirements.
We specialize in CNC turning services for turned components up to 3” bar capacity, and chucking up to 7” blanks. Automated load and unload systems, in-process inspections, and frequent quality checks allow us to maintain consistency across production runs. For customers searching for CNC turning services or a CNC turning parts manufacturer, our equipment and process control systems allows Triangle to meet your next projects needs. Every job is inspected, ensuring repeatability and documented quality from first article through final shipment.
Our cylindrical CNC roll grinding services and CNC OD/ID grinding capabilities are engineered to achieve superior roundness, straightness, and concentricity. These precision CNC grinding services are particularly valuable for rotating components where imbalance, runout, or surface irregularities can affect performance.
By combining CNC turning with cylindrical CNC precision grinding, we maintain tighter total indicator runout (TIR) and achieve consistent diameter tolerances across production runs. This integrated approach allows us to deliver production-ready shafts, pins, and precision cylindrical components that meet strict application requirements in automotive, hydraulic, and industrial equipment markets.
Triangle Machine Products has been a trusted turning company for more than six decades. Our 47,000 sq. ft. Cleveland facility supports OEMs across automotive, industrial equipment, hydraulic systems, and heavy machinery markets.
As a precision CNC turning services provider, we focus on application-driven manufacturing — delivering engineered solutions. While some parts may be produced through alternative forming methods, those processes cannot match the tight tolerances and part configurations achieved through CNC precision turning.

WHAT IS CNC TURNING, AND HOW IS IT DIFFERENT FROM CNC MILLING?
CNC turning is a machining process where material rotates on a CNC turning machine while a cutting tool shapes the outside or inner diameter to produce cylindrical parts like shafts, pins, and collars. CNC milling rotates the cutting tool instead of the part and is used for flats, slots, and complex geometries. Precision CNC turning services combine CNC turning and milling to complete multi-feature components in one setup.
WHAT MATERIALS, DIAMETERS, AND TOLERANCES CAN YOUR PRECISION CNC TURNING SERVICES HANDLE?
Our precision CNC turning services machine carbon steel, alloy steel, and stainless steel components up to 3” bar capacity, with chucking up to 7” blanks. If your part exceeds our current capabilities, please inquire, for the right project, Triangle will invest in additional equipment and capacity.
