2021 Doosan DNM-4500S CNC Vertical Mill

The 2021 Doosan DNM-4500S is a high-performance vertical machining center offering 31.5-inch X, 17.7-inch Y, and 20.1-inch Z axis travels, designed for midsize parts with speed and precision. The rigid Meehanite casting supports a 39.4-inch by 17.7-inch table rated for 1,320 pounds. A 15,000-RPM Big-Plus CAT-40 spindle driven by a 25-horsepower motor delivers 86.9 foot-pounds of torque, optimized with a spindle chiller and 300 PSI through-spindle coolant. Tool exchanges are seamless via a 30-tool side-mount toolchanger with 1.2-second tool-to-tool and 3.2-second chip-to-chip time.

With rapid traverses reaching 1,653 inches per minute on X and Y and 1,417 inches per minute on Z, this machine maintains high productivity. The FANUC 0i-M Plus control, 4th-axis wiring, Tsudakoma rotary table compatibility, probing readiness, and chip auger ensure lights-out automation readiness. Compared to other VMCs in its class—such as the Haas VF-2SS or Brother Speedio S700X1—the DNM-4500S stands out for its power, rigidity, and thermal stability under continuous load conditions.
