OKUMA MULTUS B300II – 2015
USED OKUMA MULTUS B300II – 2015
The OKUMA MULTUS B300II – 2015 is a premium multitasking CNC turn-mill center designed for complex, high-precision machining in a single setup. Built by Okuma, one of Japan’s most respected CNC manufacturers, the MULTUS BII series is engineered to combine turning, milling, drilling, and multi-axis contouring into one highly efficient machine platform. The B300II sits in the 8–10 inch chuck class and is widely used in aerospace, automotive, medical, and precision engineering industries where reducing setups and increasing machining accuracy is critical.
The 2015 MULTUS B300II is known for its advanced B-axis head, which allows full multi-angle milling capability along with a powerful main spindle and optional sub-spindle configuration. This enables complete machining of complex components in a single cycle, significantly reducing production time and improving part consistency. According to Okuma specifications, the machine is designed for high-mix, low-to-medium volume production with strong emphasis on flexibility and automation readiness.
One of the key strengths of the MULTUS B300II is its ability to eliminate multiple setups. Instead of moving a part between a lathe and a machining center, the machine can perform both operations in one clamping. This reduces human error, improves geometric accuracy, and increases throughput—especially valuable for complex components like aerospace fittings, hydraulic bodies, and precision shafts.
The machine typically features a 10-inch main spindle, high-speed milling spindle (up to 6,000 RPM), C-axis control, and a B-axis head with wide angular movement for complex geometry machining. Tool capacity can range from 20 tools up to 120 tools depending on configuration, making it highly adaptable for different production requirements.
Okuma’s OSP control system is another major advantage. Most 2015 units are equipped with OSP-P300 series controls, offering conversational programming, collision avoidance systems, and strong multitasking synchronization between spindle, turret, and milling head. This integrated control architecture improves reliability and reduces downtime in production environments.
The MULTUS B300II is also designed with thermal stability in mind. Okuma’s Thermo-Friendly Concept helps maintain machining accuracy even during long production cycles or fluctuating shop temperatures, which is essential for tight-tolerance components.
Overall, the 2015 MULTUS B300II is considered a high-value used mill-turn machine because it delivers near full “done-in-one” manufacturing capability while maintaining strong rigidity, accuracy, and long-term reliability.
