2019 DOOSAN DNM750-50-II VERTICAL MACHINING CENTERS

Technical Description

The 2019 Doosan DNM750-50-II is a second-generation 3-axis large-format vertical machining center configured with an ISO No. 50 (CAT50) spindle taper for heavy-duty cutting applications demanding maximum torque and rigidity at the spindle-tool interface. The "-50" designation distinguishes this variant from the standard CAT40 DNM750-II, with the larger taper providing significantly higher tool clamping force and enabling the use of large-diameter face mills, boring heads, and heavy-duty cutting tools suited for aggressive material removal in steel, cast iron, and stainless steel. The machine provides an X-axis travel of 1,630 mm (64.2 in), Y-axis travel of 762 mm (30.0 in), and Z-axis travel of 650 mm (25.6 in), served by a 1,630 x 760 mm worktable with a 1,500 kg maximum load capacity. The spindle delivers 22 kW (continuous) at a standard maximum speed of 8,000 RPM with a torque rating of 353 Nm, providing exceptional cutting force for large-diameter tooling applications. An optional 10,000 RPM configuration is available. The DNM750-50-II is governed by the Fanuc 0i-MF CNC control with a 15-inch touchscreen interface and full G-code compatibility. A 40+1 arm-type automatic tool changer, linear roller guideways on all axes, and integrated chip management are standard. The machine occupies a floor footprint of approximately 3,850 x 3,480 mm (151.6 x 137.0 in), stands approximately 3,170 mm (124.8 in) tall, and weighs approximately 14,000 kg (30,865 lb). The DNM750-50-II is particularly well-suited for aerospace, energy, and heavy industrial component machining.
