USED OKUMA MULTUS B400-W – 2008

The OKUMA MULTUS B400-W – 2008 is a high-end multitasking CNC turn-mill center designed for full-complete machining in a single setup. Built by Okuma, a leading Japanese CNC machine manufacturer, the MULTUS B400-W combines turning, milling, drilling, tapping, and full 5-axis contouring capability into one rigid and highly productive platform. It belongs to the premium class of mill-turn machines and is widely used in aerospace, oil & gas, automotive, and precision engineering industries where complex parts and tight tolerances are required.

The 2008 MULTUS B400-W is engineered around a powerful main spindle system, a full B-axis milling head, and an optional sub-spindle configuration, allowing both front-side and back-side machining in one cycle. According to verified machine specifications, it features a 15-inch chuck, up to 2,800 RPM main spindle speed, and a 40-tool automatic tool changer system. The machine also supports live tooling speeds up to 10,000 RPM, making it suitable for both heavy cutting and high-precision milling operations.

One of the key strengths of the B400-W is its ability to eliminate multiple setups. Instead of moving a part between a lathe and a milling machine, the entire machining process is completed in one clamping. This drastically reduces setup time, improves part accuracy, and increases production efficiency—especially important in complex components like hydraulic bodies, aerospace fittings, and turbine parts.

The machine typically includes X, Y, Z, W, B, and C-axis control, allowing full multi-axis machining flexibility. The B-axis head enables angular machining, while the C-axis provides full spindle interpolation for contouring operations. Many configurations also include sub-spindle support with synchronized machining capability, which further enhances productivity for complete part machining.

Okuma’s OSP-P200L control system is another major advantage. It provides conversational programming, advanced multi-axis synchronization, and strong stability during complex machining cycles. Because Okuma designs both the machine and control in-house, the system is highly integrated, reliable, and optimized for multitasking performance.

Structurally, the MULTUS B400-W is built with a heavy-duty casting frame designed to absorb vibration and maintain rigidity during aggressive cutting. This makes it suitable for machining difficult materials such as stainless steel, titanium, and high-strength alloys.

Overall, the 2008 OKUMA MULTUS B400-W remains a highly respected machine in the used CNC market due to its multitasking capability, rigid construction, and ability to replace multiple machines with one advanced platform.
