OKUMA LU45-N CNC LATHE

Technical Description

This heavy-duty CNC lathe is engineered for precision turning and complex cylindrical component manufacturing. It features substantial X-axis travel of 26 inches and extended Z-axis travel of 120 inches, accommodating workpieces up to 121 inches in center distance. The machine accommodates a maximum turning diameter of 23 inches (XA configuration) or 18 inches (XB configuration), with a swing over bed of 33 inches, enabling large-diameter part machining. Equipped with dual 24-inch Noble 4-jaw chucks featuring 12.5-inch bores for enhanced workpiece holding capacity, the lathe supports versatile clamping configurations. The 12-station upper turret and 8-station lower turret, combined with an integrated follow rest on the lower turret, facilitate multi-tool operations and extended-length workpiece support. The 10.23-inch spindle bore with A2-20 nose accommodates various tooling requirements, while the MT No. 5 quill with 5.12-inch diameter provides ancillary tooling capability. Variable spindle speeds ranging from 31 to 900 RPM enable optimization across diverse material types and cutting conditions. Powered by a 50 HP continuous-duty (60 HP 30-minute) motor on 220/480V three-phase, 60Hz electrical service, this machine delivers substantial cutting force and torque. Weighing 56,217 pounds, the robust construction ensures rigid workholding and precision maintaining vibration-free operation essential for repeatable tolerances in production runs.
