2021 OKUMA M660V VERTICAL MACHINING CENTER

Technical Description

The 2021 Okuma M660V is a 3-axis vertical machining center built on Okuma's heavy-duty double-column bridge structure, designed for high-rigidity cutting of large, complex workpieces in steel, cast iron, and aluminum. As a precursor or complement to the GENOS M660V within Okuma's product line, the M660V emphasizes structural mass and thermal stability through the Thermo-Friendly Concept (TFC), which monitors and compensates for heat-induced dimensional drift without requiring extended warm-up periods. The worktable measures 60.24" x 25.98" (1,530 x 660 mm) with axis travels of 59.06" in X, 25.98" in Y, and 25.98" in Z. The CAT40/BT40 Big-Plus spindle provides a standard maximum speed of 8,000 RPM with continuous power of approximately 15 HP, suitable for heavy roughing as well as semi-finishing in a variety of materials. Optional spindle configurations at 15,000 or 20,000 RPM are available for high-speed aluminum applications. A standard 20-tool arm-type ATC provides efficient tool changes between operations. The machine runs on the Okuma OSP-P200M control, which features conversational programming, servo control with absolute encoders, and optional network connectivity. Coolant, chip conveyor, and full splash guarding are included. Overall footprint and weight are consistent with Okuma's double-column VMC class, making the M660V suited for job shops and production facilities requiring a stable, long-service-life platform.
