OKUMA LU15M CNC LATHE

Technical Description

This CNC lathe features an X-axis travel of 10.24" / 5.51" and Z-axis travel of 25.20" / 24.21", accommodating a maximum turning length of 23.62" and a maximum turning diameter of 10.62". The machine offers substantial swing dimensions: 20.87" over the bed, 14.96" over the carriage, and 12.99" over the cross slide, enabling versatile workpiece handling. It is equipped with a JIS-A2-6 standard headstock and main spindle nose, supporting a spindle bore diameter of 2.44". The spindle speed reaches up to 4500 RPM, facilitating high-speed machining operations. Rapid traverse speeds are 590 IPM on the X-axis and 787 IPM on the Z-axis, which allows efficient, fast tool positioning and machining cycles. The tool turret configuration includes 12 positions on the upper turret and 8 on the lower turret, enabling complex multi-tool operations and reducing tooling changeover times. The cut feed rates on both X and Z axes range broadly from 0.0001" to 40,000 inches per revolution (IPR), supporting both precision finishing and aggressive material removal. The machine footprint measures 156" in length, 83" in width, and 76" in height, weighing approximately 12,000 lbs, reflecting robust construction for durability and stability during operation. This lathe is designed for precision machining of cylindrical components, offering a combination of axis travel, spindle power, and tooling capacity that suits medium to large-size workpieces with intricate tooling needs.
