OKUMA MULTUS B550 HORIZONTAL MACHINING CENTER

Technical Description

The OKUMA MULTUS B550 is a high-performance horizontal multitasking machining center designed for complex, high-precision turning and milling operations. It features a maximum main spindle turning diameter of 32.680" (830 mm) and a main spindle chuck diameter of 18.000" (457 mm), enabling the machining of large and intricate workpieces. The machine is equipped with two main spindles, allowing for efficient part transfer and simultaneous operations, while the main spindle delivers up to 3,000 RPM and 50 HP (37 kW) for robust cutting performance. The MULTUS B550 supports one simultaneous cutting tool, ensuring precise and efficient machining cycles. Its rapid traverse rates are 1,574 ipm (40 m/min) on the X, Y, and Z axes, providing swift tool movements and reduced non-cutting time. The machine integrates a 240° B-axis range with a 5,000 RPM H1-milling spindle, supporting advanced multi-axis capabilities and versatile tooling options. The standard H-1 dual-function spindle head utilizes CAPTO C8 interface for quick tool changes and high rigidity. Designed for multitasking, the MULTUS B550 combines turning, milling, drilling, and boring in a single setup, enhancing productivity and accuracy. Its orthogonal 3-axis configuration and large working range ensure compatibility with a wide array of applications, from heavy-duty cutting to fine finishing. The machine is equipped with advanced CNC controls and automation-ready features, making it ideal for high-mix, high-volume production environments.
