USED OKUMA LR-10 – 1990

The Okuma LR-10 is a compact CNC turning center that earned a strong reputation throughout the manufacturing industry for its reliability, productivity, and innovative twin-turret design. Manufactured by Okuma, one of Japan’s leading CNC machine tool builders, the LR-10 was engineered to maximize production efficiency while maintaining the accuracy and durability that Okuma machines are known for worldwide. Even decades after its introduction, the LR-10 remains a desirable machine in the used CNC marketplace because of its robust construction, dependable performance, and ability to reduce cycle times through simultaneous machining operations.

The LR-10 was specifically designed for high-volume turning applications where productivity and part consistency are critical. Unlike traditional single-turret lathes, the LR-10 features dual turrets that can machine a part simultaneously, significantly reducing cycle times and increasing throughput. This capability made the machine particularly attractive to automotive suppliers, electronics manufacturers, aerospace subcontractors, and general production machining facilities.

A typical 1990 Okuma LR-10 features a maximum turning diameter of approximately 8 inches, maximum turning length of approximately 12 inches, and a spindle capable of speeds up to 4,500 RPM. Most machines utilize a 6-inch hydraulic chuck and are equipped with dual 8-station turrets. The machine is commonly powered by the reliable Okuma OSP5000L CNC control, which provides excellent programming capability and machine diagnostics. The slant-bed construction improves rigidity, chip evacuation, and overall machining performance.

Industries including automotive manufacturing, aerospace machining, electronics production, fluid power manufacturing, medical device production, and contract machining have relied on the LR-10 for decades. The machine is particularly effective for producing shafts, bushings, fittings, connectors, valves, and other precision-turned components in medium to high-volume production environments.

One reason the 1990 Okuma LR-10 remains popular today is its exceptional durability. Many machines continue operating successfully after decades of service, demonstrating the quality engineering and robust construction standards that have made Okuma one of the most respected names in CNC machining. For manufacturers seeking a dependable production lathe with proven performance, the LR-10 continues to offer excellent value in the used machine market.
