USED OKUMA MULTUS B400-W – 2007

The OKUMA MULTUS B400-W – 2007 is a premium multitasking CNC turn-mill center designed for high-precision, complex component manufacturing in a single setup. Manufactured by Okuma, a leading Japanese machine tool builder, the MULTUS B400-W belongs to the early-generation “Multitasking Machine Tool” series that integrates turning, milling, drilling, tapping, and full multi-axis contouring into one rigid platform. It is widely used in aerospace, oil & gas, automotive, and heavy precision engineering industries where productivity and accuracy are equally critical.

The 2007 MULTUS B400-W is built on a heavy-duty slant-bed casting with full 8-axis capability, allowing simultaneous multi-operation machining. According to verified machine specifications, it typically includes a 15-inch hydraulic chuck, main spindle speed up to 3,000 RPM, and a 40 HP spindle motor designed for both roughing and finishing operations. The machine is equipped with a 40-tool automatic tool changer and supports live tooling up to 10,000 RPM, enabling complex milling and drilling operations without removing the part from the machine.

One of the strongest advantages of this machine is its true “complete machining” capability. Instead of transferring parts between a lathe and a machining center, the MULTUS B400-W performs turning and milling operations in one continuous cycle. This reduces setup time, eliminates alignment errors, and significantly improves dimensional accuracy—especially important for high-value components such as hydraulic blocks, aerospace housings, and precision shafts.

The machine typically features X, Y, Z, W, C, and B-axis control. The B-axis head provides angular machining flexibility ranging from negative to positive tilt, allowing complex contouring and multi-face machining without repositioning the workpiece. Many configurations also include a sub-spindle, enabling full front-side and back-side machining in a single setup, further improving productivity.

Okuma’s OSP-P200L control system is another key strength. It provides smooth multitasking synchronization between spindles, turrets, and milling heads while maintaining high stability during complex operations. Because Okuma designs both the machine and control internally, the integration is highly reliable and well-optimized for long production cycles.

Structurally, the MULTUS B400-W is known for its rigid construction and excellent vibration damping. This allows stable cutting performance even on tough materials like stainless steel, titanium, and high-strength alloys, making it suitable for demanding industrial environments.

Overall, the 2007 OKUMA MULTUS B400-W remains a highly respected multitasking CNC machine in the used market due to its rigidity, versatility, and ability to replace multiple machines with one integrated system.
