2016 OKUMA MILLAC 1052V VERTICAL MACHINING CENTERS

Technical Description

The 2016 Okuma MILLAC 1052V is a 3-axis large-bed vertical machining center from Okuma's MILLAC series, engineered for heavy-duty milling, boring, and tapping of large dies, molds, aerospace structural components, and energy sector parts. The MILLAC 1052V is built on a fixed-table, traveling-column structure with Okuma's Thermo-Friendly Concept (TFC) thermal management and linear guideway construction, providing the rigidity and thermal stability required for consistent accuracy across very large work envelopes. The worktable measures approximately 126" x 41.3" (3,200 x 1,049 mm) — among the longest table configurations in the MILLAC series — with axis travels of approximately 120.03" in X, 41.3" in Y, and 31.5" in Z. Rapid traverse is 1,181 IPM (30 m/min) on all linear axes. The CAT50 gear-head spindle delivers approximately 30 HP (22.4 kW) continuous with a maximum speed of 6,000 RPM, optimized for high-torque roughing and semi-finishing in ferrous materials. A 32-tool arm-type ATC provides chip-to-chip changes in approximately 6 seconds. The Okuma OSP-P200M control manages all three axes with servo drives and absolute encoders, providing G-code and conversational programming, Collision Avoidance System (CAS), Machining Navi for chatter suppression, and Ethernet connectivity. Machine weight is approximately 56,580 lbs, reflecting the substantial cast-iron construction of this large-format VMC platform.
