OKUMA LB3000 EX CNC LATHES

Technical Description

The Okuma ES-L8II is a precision CNC turning center designed for high-speed production work and complex part manufacturing. This machine features an 18.5-inch swing diameter with a 17.7-inch machining length, accommodating workpieces up to 16.1 inches in turning diameter. The 12-inch, 3-jaw hydraulic chuck provides secure part clamping, while the 3.15-inch bar capacity enables efficient bar-fed operations for continuous production runs. Powered by a robust 30 HP main spindle motor, the ES-L8II delivers speeds up to 4,200 RPM, enabling aggressive cutting parameters and reduced cycle times. The machine incorporates three controlled axes (X, Z, and C) with ultra-precise ball screws and pre-loaded ball nut assemblies mounted centrally between the ways for optimal drive conditions and accuracy. Positioning accuracy reaches 0.00059 inches on the X-axis, supporting tight tolerances required in modern manufacturing. The ES-L8II features a V-12 slotted turret with hydraulic bolt clamping, maximizing tooling capacity and flexibility for complex multi-operation programs. Live tooling capability enables advanced milling, drilling, and threading operations directly on the lathe, eliminating secondary operations. The OSP-P200L THINC control system provides intuitive CNC programming and monitoring, integrating Okuma's intelligent technologies for streamlined setup and enhanced productivity. Additional standard equipment includes an automatic lubrication system, right-side chip conveyor, and hollow-type actuating cylinder for continuous unmanned operation.
