OKUMA LB-3000 EXII MWY CNC LATHES

Technical Description

This advanced CNC lathe features a robust design with a swing over bed of 22.83 inches and a swing over saddle of 18.5 inches, supporting a maximum turning diameter of 13.39 inches. The distance between spindles is 42.72 inches, accommodating versatile workpiece lengths. Equipped with a 10-inch and 6-inch chuck, the machine handles bar capacities up to 3 inches and 1.7 inches, respectively. Axis travels are substantial: X-axis at 10.24 inches, Z-axis at 39.76 inches, and Y-axis at 4.53 inches with a range of +276/-1.77 inches, enabling complex multi-axis machining. C-axis indexing provides precision down to 0.001 degree for both main and sub-spindles. Rapid traverse rates reach 984 IPM (X), 1,181 IPM (Z), and 492 IPM (Y), ensuring efficient operation. The spindle nose is A2-8 with a JIS Flat Ø140, and spindle speeds are 6,000 RPM (main) and 5,000 RPM (sub), delivering 30 HP and 15 HP, respectively. Main spindle bore diameter is 3.15 inches, while the sub-spindle bore is Ø2.44 inches. The front bearing diameter is 4.72 inches, and the spindle ID taper is 2 degrees. The machine includes a tailstock and tool pre-setter for enhanced setup and accuracy. Overall dimensions are 134.64 inches (L) x 80.35 inches (W) x 88.6 inches (H), with a weight of 15,101 lbs. Control is managed by the OSP-P300L, providing intuitive operation, advanced diagnostics, and seamless integration of multi-axis functions for high-precision, efficient production.
