2018 DOOSAN DNM400A VERTICAL MACHINING CENTERS

Technical Description

The 2018 Doosan DNM400A is a 3-axis vertical machining center built on the DNM 400 platform, an established design offering a practical balance of compact footprint and capable machining envelope for small- to mid-sized prismatic workpieces. The machine provides an X-axis travel of 635 mm (25.0 in), Y-axis travel of 435 mm (17.1 in), and Z-axis travel of 510 mm (20.1 in), supported by a 790 x 435 mm worktable. The spindle is rated at 11 kW (continuous) with a maximum speed of 8,000 RPM, providing adequate torque for general-purpose milling and drilling of ferrous and non-ferrous materials. The DNM400A is governed by the Fanuc 0i CNC control, a well-established platform widely supported in production environments and familiar to operators across the industry. Box guideways on the Y and Z axes and linear guides on the X-axis contribute to structural rigidity during heavy cutting passes, while an integrated automatic tool changer supports multi-tool production sequences. The machine's cast iron column and base construction resists vibration and maintains dimensional accuracy over extended production runs. Roller-type linear guides on the X-axis provide smooth, low-friction motion for efficient positioning. The DNM400A occupies a floor footprint of approximately 2,200 x 2,060 mm (86.6 x 81.1 in) and stands approximately 2,853 mm (112.3 in) tall, with a machine weight of approximately 4,000 kg (8,818 lb). This model is suitable for contract machining shops and production cells requiring a reliable, space-efficient VMC for standard milling, drilling, boring, and tapping operations.
