Overview

The Okuma MULTUS B200 is a compact, highly capable mill-turn machining center that integrates turning, milling, drilling, and grinding operations in a single setup. Designed for complex prismatic and rotational parts, the MULTUS B200 features a B-axis milling spindle that tilts ±120 degrees, enabling true 5-axis simultaneous machining of intricate contours and compound angles.

The machine's combined main and sub-spindle configuration allows complete front-to-back machining without operator intervention, dramatically reducing cycle times and eliminating positional errors associated with re-chucking. The high-torque main turning spindle and powerful milling spindle work in concert to tackle challenging materials including titanium, Inconel, and hardened steels.

Okuma's OSP-P300S control provides seamless multi-axis, multi-spindle coordination through a single intuitive interface. Features such as Collision Avoidance System (CAS), Machining Navi, and 3D virtual machining simulation help operators achieve first-part accuracy and protect the machine from costly crashes.

The MULTUS B200 is widely adopted in aerospace, medical, energy, and precision engineering sectors where component complexity demands the highest levels of multi-tasking performance in a compact machine envelope.

Frequently Asked Questions

01 What is the B-axis range on the MULTUS B200?

The B-axis on the MULTUS B200 tilts from –30° to +210°, giving the milling spindle exceptional angular flexibility for compound-angle machining and undercut features.

02 Does the MULTUS B200 have a sub-spindle?

Yes. The MULTUS B200 includes an integrated sub-spindle with the same speed and power as the main spindle, enabling complete front-and-back machining in a single setup without re-chucking.

03 What is the Collision Avoidance System (CAS)?

CAS is Okuma's real-time 3D interference check that monitors all machine components, tooling, workpiece, and fixtures during program execution and simulation. It halts motion before a collision occurs, protecting the machine and workpiece.

04 How many tools can the MULTUS B200 hold?

The MULTUS B200 uses a combination of turret stations and milling spindle tool magazine positions, supporting up to 36 tools in a typical configuration, reducing tool changeovers in complex programs.

05 Is the MULTUS B200 suitable for titanium machining?

Yes. The high-torque main spindle and rigid box-way structure make the MULTUS B200 well-suited for titanium, Inconel, and other difficult-to-cut aerospace alloys, provided appropriate tooling and cutting parameters are used.
