2019 OKUMA MILLAC 1052VII VERTICAL MACHINING CENTERS

Technical Description

The 2019 Okuma MILLAC 1052VII is a 3-axis large-bed vertical machining center and the current-generation successor to the original MILLAC 1052V, featuring updated spindle technology, refined linear guideway geometry, and integration with Okuma's latest OSP control platform. The MILLAC 1052VII is built on a traveling-column fixed-table structure with Thermo-Friendly Concept (TFC) thermal management. The worktable measures approximately 86.61" x 41.34" (2,200 x 1,050 mm) — notably shorter than the original 1052V — with axis travels of approximately 80.71" in X, 41.73" in Y, and 31.50" in Z. The spindle delivers approximately 24.8 HP (18.5 kW) continuous with a standard maximum speed of 4,000 RPM; optional spindle heads at 6,000, 10,000, 12,000, and 15,000 RPM are available for higher-speed applications. Rapid traverse is 1,181 IPM (30 m/min) on all linear axes. A 40-tool arm-type ATC provides chip-to-chip tool changes in approximately 6 seconds. The Okuma OSP-P300M control provides touchscreen navigation, conversational and G-code programming, Machining Navi for chatter suppression, Collision Avoidance System (CAS), and Okuma Connect Plan remote monitoring. The MILLAC 1052VII is well suited for aerospace, energy, and heavy manufacturing applications requiring a reliable large-format VMC with modern control capability.
