OKUMA LB45-III/2000 CNC LATHES

Technical Description

This CNC lathe features a robust design engineered for high-precision turning of large workpieces. The swing over bed is 33.46 inches, allowing ample clearance for oversized parts, while the swing over saddle and maximum turning diameter are both 21.65 inches, ensuring compatibility with a wide range of cylindrical components. The maximum turning length reaches 78.74 inches, supporting extended machining operations. The spindle utilizes an A2-11 Big Bore nose with a bore diameter of 7.28 inches, accommodating large bar stock and enabling efficient through-feed applications. Spindle speed is variable from 12 to 2800 RPM, driven by a powerful 60/50 HP motor for versatile material removal rates and surface finishes. Axis travel is extensive, with X-axis movement of 13.58 inches and Z-axis travel of 80.31 inches, complemented by rapid traverse rates of 472 IPM on both axes for swift tool positioning. The machine is equipped with a V12 turret providing 12 tool stations, facilitating complex multi-tool operations without manual intervention. The tailstock features a 5.12-inch quill diameter and 5.91 inches of stroke, offering reliable support for long workpieces. Weighing approximately 20,944 lbs, this lathe delivers exceptional rigidity and vibration damping for consistent accuracy and surface quality in demanding production environments.
