OKUMA LU-45M CNC LATHE

Technical Description

This CNC lathe features a 15" chuck with a maximum swing over the bed of 33.46" and a maximum turning diameter of 22.83", supporting turning lengths up to 118.11". It accommodates bar stock up to 4.33" in diameter through a 4.33" thru bore. The spindle is powered by a 30 HP motor capable of speeds up to 3000 RPM and equipped with an A2-11 spindle nose. The machine houses two turrets with 12 and 10 tool positions, respectively, allowing highly versatile tooling setups. The X-axis travel is 11.81" with a Z-axis travel of 37.4", and the rapid traverse rates are 787 IPM for the X-axis and 945 IPM for the Z-axis, facilitating efficient movement and cycle times. The machine weighs approximately 33,070 lbs and measures 205" in length, 90" in width, and 94" in height. It is controlled by the Okuma OSP 300L CNC system, an open-architecture, operator-focused platform that streamlines setup and operation with centralized data access and user-friendly interface. Overall, this lathe is engineered for heavy-duty, precision turning of large diameter and long-length parts, combining powerful spindle performance, extensive tooling capacity, and rapid axis motion to optimize productivity and flexibility in a robust industrial footprint. Its dual turret configuration supports complex multi-tool machining, making it suitable for demanding manufacturing environments requiring both high horsepower and precise control.
