OKUMA LU45IIM CNC LATHE

Technical Description

This is a heavy-duty Okuma CNC lathe equipped with the OSP-P300LA control system, designed for large-scale production turning operations. The machine features an impressive 25.59-inch maximum cutting diameter with an 80-inch distance between centers, accommodating workpieces up to 10.20 inches in bar stock capacity. The 24.8-inch hydraulic chuck provides secure workholding for extended production runs. With 17.32 inches of X-axis travel and 82.28 inches of Z-axis travel, this lathe offers substantial working envelope flexibility for complex geometries. The 60 HP main spindle motor delivers 900 RPM with a 10.23-inch bore and A2-20 nose configuration, enabling powerful cutting forces for roughing and finishing operations. Rapid traverse rates of 591/787 IPM ensure efficient non-cutting movements across both axes. The machine is equipped with dual tooling capacity—12 positions on the primary turret and 10 positions on the secondary turret—enabling extended production runs without tool changes. A hydraulic steadyrest provides rigid support for long, slender workpieces, minimizing deflection and improving surface finish quality. The Windows-based OSP-P300LA control offers open-architecture programming with intuitive operator interface, featuring dual-core processor technology for reliable performance and advanced machining capabilities. This configuration makes the lathe ideal for high-volume production of large-diameter components requiring precision turning and multiple tool operations.
