OKUMA MULTUS B750-W/4000 CNC LATHE

Technical Description

This advanced 5-axis turning and milling center features a robust 24" chuck with a maximum swing over saddle of 41.34", making it suitable for large workpiece machining. The primary turning spindle operates at 2000 RPM with 50/40 HP AC motor power and an A2-20 spindle nose, while the dedicated milling spindle delivers 5000 RPM with comparable 50/40 HP output and 372 ft-lbs torque. Rapid traverse rates reach 1575 IPM across the machine's extensive work envelope: 42.52" X-axis travel, 165.94" Z-axis travel, ±12.99" Y-axis capability, and 133.66" W-axis travel. The machine incorporates simultaneous 5-axis interpolation with C-axis precision indexing to 0.001 degrees and B-axis tilting from -30 to 210 degrees, enabling complex multi-sided part production in a single setup. An integrated 80-tool magazine with Capto C8 spindle taper provides flexibility, accommodating tools up to 5.31" diameter (11.81" adjustable), 23.6" length, and 66 lbs weight. The 95,000-lb structural mass ensures stability during high-speed operations. With a 178.9" distance between spindles, this configuration permits simultaneous turning and milling operations or sequential processing of extended components. Designed for complete part machining of complex geometries, this machine minimizes setup time and throughput cycles while maintaining precision in both rotational and linear axes, making it ideal for aerospace, medical, and precision manufacturing applications requiring high-capacity, multi-function capabilities.
