VMC for Cutting Large, Complex Parts

Okuma’s Genos M560-VA-HC VMC combines a high column design and CAT 40 Big-Plus spindle to cut large, complex parts. The larger work envelope minimizes restrictions on workpieces, tool lengths and the rotary table. A rigid, thermally-stable, double-column construction enables the CNC machine to withstand thermal deformation to promote improved machining performance.

The machine features a maximum machining volume of 1,050 × 560 × 460 mm (41.34" × 22.05" × 18.11") and a table size of 560 × 1300 mm (22.05" × 51.18"). The maximum load capacity is 900 kg (1,980 lbs). The X- and Y-axis rapid traverse speeds are 40 m/min. (1,575 ipm) while the Z-axis rapid traverse speed is 32 m/min. (1,262 ipm). The machine is equipped with an ATC magazine capacity of 32 tools and features a spindle speed of 15,000 rpm.

A 30/25 hp (22/18.5 kW) spindle with 146 foot-pounds of torque enables the machine to cut metals such as titanium, Inconel, stainless steel and aluminum. A separate ATC door enables tool changing without interrupting the machining process. The table moves in Y axis, while the spindle moves in X and Z axes, enabling a smaller machine footprint, rapid feed rates, precise cutting and smooth surface finishes, the company says.

The machine comes standard with the company’s thermal deformation compensation technology. Pretension ballscrews and bi-directional spindle cooling are designed to enable better control of the machining process. Optional Collision Avoidance and Machining Navi Intelligent technologies are available.
