1997 OKUMA MB56VA VERTICAL MACHINING CENTER

Technical Description

The 1997 Okuma MB56VA is a 3-axis vertical machining center representing an enhanced variant of the MB56V platform, featuring a higher-output spindle motor and updated control system for improved productivity in high-speed and high-power applications. The MB56VA retains the double-column bridge frame, Thermo-Friendly Concept (TFC) thermal management, and linear guideway construction of the MB series, with the 'A' designation indicating an upgraded spindle and drive package. The worktable measures 51.18" x 22.05" (1,300 x 560 mm) with axis travels of 41.34" in X, 22.05" in Y, and 18.11" in Z. Rapid traverse is 1,417 IPM (36 m/min) on X/Y and 1,181 IPM on Z. The CAT40/BT40 Big-Plus taper spindle delivers approximately 30 HP continuous with a maximum speed of 15,000 RPM via a built-in direct-drive motor, enabling both heavy roughing and high-speed finishing across a wide range of materials and applications. A 32-tool arm-type ATC performs chip-to-chip tool changes in approximately 4 seconds. The Okuma OSP-U10M control provides conversational and G-code programming, Machining Navi for chatter suppression, Collision Avoidance System (CAS), and Ethernet connectivity. Overall machine dimensions are approximately 118.3" x 97.2" (L x W) with a height of 108.3" and a weight of approximately 16,534 lbs (7,500 kg).
