2021 DOOSAN DNM4500S VERTICAL MACHINING CENTERS

Technical Description

The 2021 Doosan DNM4500S is a 3-axis high-speed vertical machining center built on the same rigid cast iron platform as the DNM4500, configured as standard with a direct-drive 15,000 RPM spindle for applications demanding elevated surface speeds and precise finish machining. The "S" designation denotes the high-speed spindle variant, distinguishing it from the standard 8,000 RPM DNM4500. The machine provides an X-axis travel of 800 mm (31.5 in), Y-axis travel of 450 mm (17.7 in), and Z-axis travel of 510 mm (20.1 in), served by a 1,000 x 450 mm worktable with a 600 kg maximum load capacity. The integrated spindle delivers 18.5 kW of continuous power at up to 15,000 RPM with a torque rating of 118 Nm, making this configuration particularly well-suited for aluminum, titanium, aerospace alloys, and precision mold and die work where high spindle speeds translate directly into improved surface finish and cycle times. The DNM4500S is governed by the Fanuc 0i-MF Plus CNC control with a 15-inch touchscreen iHMi panel, supporting conversational programming, advanced tool management, and standard G-code compatibility. A 30+1 arm-type automatic tool changer, BT40 (CAT40) spindle taper, and linear roller guideways on all axes are standard. The machine has an overall footprint of approximately 2,640 x 1,905 mm (103.9 x 75.0 in), stands approximately 2,997 mm (118.0 in) tall, and weighs approximately 5,000 kg (11,023 lb). The DNM4500S suits production environments where high-speed machining of non-ferrous and light alloy components is a primary requirement.
