2016 OKUMA MB46VA VERTICAL MACHINING CENTER

Technical Description

The 2016 Okuma MB46VA is a 3-axis vertical machining center representing an updated iteration of the MB46V platform, incorporating refined linear guideway geometry and an enhanced spindle assembly for improved surface finish and thermal performance. The MB46VA retains the same core architecture as the MB46V — Okuma's Thermo-Friendly Concept (TFC), double-column bridge frame, and OSP control family — while improving positioning accuracy and rapid traverse characteristics. The worktable measures 39.37" x 18.11" (1,000 x 460 mm) with axis travels of 30" in X, 18.11" in Y, and 18.11" in Z, consistent with the MB46V footprint. 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 15 HP (11 kW) continuous with a standard maximum speed of 8,000 RPM, suitable for general-purpose steel and aluminum applications in a mid-size work envelope. The Okuma OSP-U100M control provides conversational and G-code programming, canned cycles, Okuma's Collision Avoidance System (CAS), and Ethernet connectivity for DNC and remote monitoring. A 20-tool arm-type ATC is standard. Machine footprint is approximately 106" x 86" (L x W) with a height of 109" and a weight of approximately 14,300 lbs, making the MB46VA a compact, production-capable VMC well suited for repetitive precision work.
