OPEN POSSIBILITIES

Transcending the Legendary LB Okuma's best and long-selling LB Series, the spearhead of a wide range of CNC lathes, now provides new functionality for today's requirements, breakthrough possibilities for the next generation, and more reliability to satisfy greater customer expectations. We are on a mission to "continuously enhance the LB to go beyond itself," and achieve productivity improvements linked to new strategic value chains. The machine against which all others will be measured The SPACE TURN LB EX II Series. Offering improved machining quality, speed, power and torque,...

High accuracy specifications overall assure machining with high dimensional stability Highest Quality Thermo-Friendly Concept for unparalleled dimensional stability Slanted-box bed configuration with superior construction and rigidity The next evolution of the slanted-box bed construction that has been highly praised as a "rugged, Okuma-like construction" in the SPACE TURN series. The primary units of headstock and turret on a box bed is optimally placed for outstanding dimensional stability and high rigidity. Exhibits stable machining accuracy even in heavy cutting. Okuma’s Thermo-Friendly...

Huge reduction in machining time with an original high power motor and faster machine movements Super Fast and Rigid Powerful motor on the spindle gives turning capacity of 2.7 mm2 Reduced operation time achieved with higher speed machine movements Spindle with a larger bearing internal diameter of ø100 mm can accommodate larger workpieces, and a turning capacity of 2.7 mm2 is achieved with a high-speed, wide-area full power motor. Stable, high quality machining, from heavy to high speed cutting. Z: 30 m/min (1,181 ipm) ● Spindle ● Turret tailstock rapids [Actual data*] 2 2 Cylindrical,...

Greater efficiency with highest milling performance in its class and fast tool change times Reduced operation time achieved with higher speed machine movements Compact new PREX motor gives milling performance of 144 cm3 /min Compact, high-power, high-torque PREX motor also used for milling spindle of the multitasking V12 radial turret. This combined with a powerful, highly rigid bolt clamp system greatly increases multitasking speed. ●M rotate start/stop Milling capacity 144 cm3/min (Workpiece: S45C) [Actual data*] Chip volume 144 ø16 6-flute carbide end mill Cutting speed V: 100 m/min (328...

Providing rich variation and optimum ease of use Extreme Versatility NC tailstock that shortens setup and automates center work is standard equipment Up to 10 pairs of tailstock positions can be set, enabling continuous machining of workpieces with 10 different lengths without setup. In addition, thrust can be switched between high and low without resetting the workpiece. (Tailstock thrust high/low switch: Optional) High accuracy positioning is also possible with a high speed linear guide employing a ball screw guide. ● Tailstock ● Rapid Complete multitasking with Y-axis functions One chuck...

Okuma’s Intelligent Technology reduces operator burden With revamped operation and responsiveness— ease of use for machine shops first! Smart factories are using advanced digitization and networking (IIoT) in manufacturing to achieve enhanced productivity and added value. The OSP has evolved tremendously as a CNC suited to advanced intelligent technology. Okuma’s new control uses the latest CPUs for a tremendous boost in operability, rendering performance, and processing speed. The OSP suite also features a full range of useful apps that could only come from a machine tool manufacturer,...
