2015 OKUMA MILLAC 3VA VERTICAL MACHINING CENTER

Technical Description

The 2015 Okuma MILLAC 3VA is a 3-axis vertical machining center from the Okuma-Howa MILLAC series, a compact dual-pallet platform designed for high-productivity machining of small to mid-size parts in precision applications. The MILLAC 3VA features a two-pallet automatic pallet changer (APC) that enables one part to be machined while the operator loads and unloads the second pallet, supporting near-continuous spindle utilization in production environments. The pallet measures approximately 17.7" x 12.5" (450 x 318 mm) with axis travels of approximately 22.8" in X, 14.1" in Y, and 17.7" in Z. The CAT40 taper spindle delivers approximately 7 HP continuous with a maximum speed of 6,000 RPM, providing adequate torque for steel and aluminum work within the compact work envelope. Rapid traverse is 1,181 IPM (30 m/min) on all linear axes. A standard ATC enables multi-operation machining within a single pallet setup. The machine runs on a Fanuc OM control, providing G-code programming, canned cycles for drilling and tapping, rigid tapping, and servo drives. Overall machine footprint is approximately 120" x 103" (L x W) with a height of 100" and a weight of approximately 9,900 lbs. The MILLAC 3VA is well suited for precision component manufacturing requiring high spindle utilization in a compact footprint.
