2017 Okuma GENOS M560-V CNC Vertical Machining Center

The Okuma GENOS M560-V is a double-column vertical machining center built on Okuma's Thermo-Friendly Concept, which is the reason it holds size through long runs instead of drifting as the casting warms. This 2017 machine offers a 41.34 x 22.05 x 18.11 inch machining volume over a 51.18 x 22.05 inch table, driven by a 15,000 RPM CAT40 BIG-PLUS spindle rated 30 HP, with rapid traverse of 1,575 IPM in X and Y and 1,262 IPM in Z and a 32-tool magazine. The double-column design moves the table in Y only while the spindle carries X and Z, which shrinks the footprint and keeps the moving mass balanced for accuracy at speed. Control is the Okuma OSP-P300MA, the open-architecture platform Okuma builds its own collision-avoidance and adaptive-machining apps on. This unit is configured for production work: a Lundex-Nikken 5AX-201 fourth- and fifth-axis trunnion with hydraulic clamping sits on the table, MP Systems R Series high-pressure coolant runs through the spindle, a Renishaw OTS tool setter handles offsets at the machine, and an LNS Turbo MH250 conveyor clears chips.

The GENOS M560-V is the machine that replaced Okuma's MB-56VA in the affordable-excellence line, and the differences are the ones that show up in a capability study rather than a brochure. Okuma moved to the OSP-P300 control generation, which is what brings Collision Avoidance System, Machining Navi and the rest of the app-based toolset onto a machine in this class - capability the MB generation never had. The spindle steps up to 15,000 RPM on a CAT40 BIG-PLUS interface, so the dual-contact taper holds rigidity at speeds where a standard CAT40 begins to lose it, and 30 HP behind it means that speed is usable in steel and titanium rather than only aluminum. Rapids of 1,575 IPM keep non-cutting time down on the longer tool lists the 32-pocket magazine makes practical. The Thermo-Friendly structure is the quiet differentiator: Okuma engineers the thermal behavior of the casting rather than compensating for it in software. And with the Nikken trunnion already mounted, a buyer gets simultaneous four- and five-axis work without stepping up to a dedicated five-axis machine or giving up the travels of a full-size VMC.
