2011 OKUMA MA650VB VERTICAL MACHINING CENTER

Technical Description

The 2011 Okuma MA650VB is a 3-axis vertical machining center from Okuma's MA-VB series, offering an expanded work envelope for large mold, die, and aerospace structural components. The MA650VB is built on a rigid double-column bridge frame with Thermo-Friendly Concept (TFC) thermal compensation and full linear guideway construction, ensuring consistent dimensional accuracy during extended production runs. The worktable measures 60.24" x 25.98" (1,530 x 660 mm) with axis travels of 60.24" in X, 25.98" in Y, and 24.01" in Z. The CAT50 Big-Plus taper spindle delivers approximately 20 HP continuous with a maximum speed of 6,000 RPM, providing the high torque required for heavy roughing in steel, stainless, and Inconel. Rapid traverse is 1,181 IPM (30 m/min) on all linear axes. A 32-tool arm-type ATC provides chip-to-chip changes in approximately 4 seconds. The Okuma OSP-P200M control manages all three axes with absolute encoder feedback, Okuma's Collision Avoidance System (CAS), conversational and G-code programming, and Ethernet connectivity for DNC file transfer. Standard coolant, chip conveyor, and full splash guarding are included. Overall footprint is approximately 150" x 125" (L x W) with a height of 128" and a weight of approximately 28,000 lbs, reflecting the MA650VB's position as a heavy-duty production VMC.
