OKUMA MULTUS B400II HORIZONTAL MACHINING CENTER

The OKUMA MULTUS B400II is a high-performance horizontal multitasking machining center designed for complex, high-precision production. It features a main spindle with a maximum turning diameter of 27.950" and a turning length of 61.020", supporting a 15.000" chuck diameter and a max swing of 27.950". The machine is equipped with dual main spindles, each capable of 3,800 RPM and delivering 30 HP (20 HP continuous), enabling efficient simultaneous or sequential operations. The primary tool carrier is an automatic tool changer (ATC) with capacity for up to 40 turning tools and 40 rotary tools, the latter providing up to 18 HP and 6,000 RPM for advanced milling and drilling tasks. The MULTUS B400II offers 5-axis control as standard, with options for 6-axis configurations, and includes a B-axis with a 225° range for versatile compound motion. Axis travels are X: 21.170", Y: 9.050", and Z: 60.830" (extendable to 80.510"), with rapid traverse rates of 1,575 ipm on all axes and maximum feed rates of 1,000 ipm. The machine integrates advanced technologies such as the Collision Avoidance System and Okuma’s THINC-OSP control for enhanced safety, accuracy, and ease of operation. With its robust construction, high spindle power, and flexible tooling options, the MULTUS B400II is ideal for demanding multitasking applications in aerospace, automotive, and precision manufacturing environments.
