The base column of Okuma’s Millac 852V II vertical machining center features ribbing to counter chatter and twisting during heavy-duty cutting. With its variable-speed gearhead and large-diameter spindle bearings, the VMC is capable of heavy-duty cutting and high-speed machining with high torque from low to high speeds. The worktable accommodates large, heavy workpieces ranging to 3,800 kg (8,380 lbs). The X, Y and Z axes measure 3,050 × 850 × 750 mm (120.79" × 33.46" × 29.53"), and traditional box ways on all axes provide high accuracy and rigidity over the long term, the company says. Rapid traverse rates range to 12 m/min. (472 ipm) in the X and Y axes, and to 16 m/min. (630 ipm) in the Z axis. The Cat 50 Big Plus spindle offers speeds ranging to 6,000 rpm, and torque of 481/390 Nm (355/288 foot-pounds) 30 min./continuous.
