2011 DOOSAN DNM400 VERTICAL MACHINING CENTER

Technical Description

The 2011 Doosan DNM 400 is a 3-axis vertical machining center designed for high-accuracy production machining of small to medium-sized prismatic components. Compact and efficient, the DNM 400 is a popular choice for high-density production cells in automotive, precision engineering, and general manufacturing where floor space is at a premium. The machine's rigid C-frame construction and precision linear guideways provide excellent vibration damping and geometric accuracy across the full travel range. The worktable measures 36.2 inches by 17.1 inches (920 mm x 435 mm) with a maximum table load of 1,323 pounds (600 kg). Axis travels span 30 inches (X), 17.1 inches (Y), and 20.1 inches (Z). The CAT40 spindle delivers 20 HP of continuous power at speeds up to 12,000 RPM, enabling effective machining of a broad range of materials from aluminum to hardened steel. The 30-position automatic tool changer supports complex multi-feature programs with minimal operator intervention. Equipped with a Fanuc 31i-B CNC control providing full 3-axis contouring, rigid tapping, tool life management, and AICC high-speed contouring, the DNM 400 delivers reliable performance for precision production. Standard features include flood coolant, central lubrication, and full machine enclosure. Overall machine dimensions are approximately 82 inches long by 77 inches wide by 99 inches high, with a machine weight of approximately 11,000 pounds (5,000 kg).
