USED OKUMA MULTUS U4000 – 2015

The OKUMA MULTUS U4000 – 2015 is a high-performance multitasking CNC turn-mill center designed for complete, single-setup machining of complex components. Built by Okuma, this machine belongs to the advanced MULTUS U-series, which is engineered for high rigidity, high-speed performance, and full integration of turning, milling, drilling, and 5-axis contouring operations. It is widely used in aerospace, energy, automotive, and precision engineering industries where productivity, accuracy, and process consolidation are essential.

The 2015 MULTUS U4000 is designed to handle medium-to-large precision components with excellent flexibility. It typically features a 650 mm maximum turning diameter and up to 1500 mm (and optionally 2000 mm) turning length, making it suitable for long shaft-type parts as well as complex housings. The machine is built on a rigid orthogonal bed structure that enhances stability during heavy cutting and high-precision finishing operations.

One of the strongest features of the U4000 is its advanced B-axis milling head, which provides up to a 240° swivel range and enables full multi-angle machining without re-clamping the part. This allows manufacturers to produce complex geometries in a single setup, significantly reducing cycle time and improving dimensional accuracy. The machine also supports optional sub-spindle and lower turret configurations, enabling simultaneous machining and improved production balance.

The machine typically comes with a high-speed milling spindle capable of up to 12,000 RPM and a main spindle speed up to 4,200 RPM depending on configuration. The system is designed for both heavy roughing and fine finishing, making it highly versatile across different materials such as steel, stainless steel, aluminum, and titanium.

Okuma’s integrated OSP control system (commonly OSP-P300/P500 series) provides full multitasking synchronization between all axes and spindles. It includes collision avoidance systems and advanced thermal stability features, which ensure consistent machining accuracy over long production runs. The control system is also known for its strong reliability and ease of use in both conversational and G-code programming environments.

Structurally, the MULTUS U4000 is built for heavy-duty industrial use, with strong vibration damping and rigid column construction. This allows stable cutting performance even in demanding applications such as deep drilling, interrupted cuts, and high-strength alloy machining.

Overall, the 2015 OKUMA MULTUS U4000 is considered a premium multitasking machine in the used market due to its combination of rigidity, flexibility, and high productivity in single-setup machining environments.
