USED DOOSAN MYNX 5400/50II

The DOOSAN MYNX 5400/50II is a heavy-duty 3-axis Vertical Machining Center (VMC) engineered for high-rigidity milling, drilling, tapping, and precision machining of large and demanding workpieces. Built with a robust box guideway design, a powerful BT50 spindle, and a rigid cast-iron structure, the MYNX 5400/50II delivers exceptional cutting performance for manufacturers working with steel, cast iron, stainless steel, and other difficult-to-machine materials. The machine is widely used in aerospace, automotive, energy, mold & die, heavy equipment, and general engineering industries where consistent accuracy and high material removal rates are essential.

The machine provides 40.2 inches (1,020 mm) of X-axis travel, 21.7 inches (550 mm) of Y-axis travel, and 20.9 inches (530 mm) of Z-axis travel, making it suitable for machining large fixtures, tooling plates, molds, machine components, and structural parts. Its rigid box guideways provide outstanding vibration damping during heavy cutting, while the one-piece Meehanite cast construction ensures excellent thermal stability and long-term machining accuracy. Whether roughing large steel components or performing precision finishing operations, the DOOSAN MYNX 5400/50II delivers reliable performance and excellent surface finishes.

Powering the machine is a 30 HP (22 kW) geared spindle with a maximum speed of 6,000 RPM and a BIG PLUS BT50 spindle taper, providing high torque for demanding machining applications. The machine is equipped with a 24-tool automatic tool changer designed for quick and reliable tool changes, while rapid traverse rates of 1,181 IPM (X/Y) and 945 IPM (Z) help reduce non-cutting time. Many used machines include valuable options such as through-spindle coolant, chip conveyor, rotary tables, 4th-axis preparation, probing systems, high-pressure coolant, and tool setters, allowing manufacturers to further increase productivity.

The machine is commonly equipped with the Fanuc i-Series CNC Control, providing intuitive programming, high-speed processing, USB and Ethernet connectivity, and compatibility with modern CAD/CAM software. Combined with its heavy-duty construction and proven reliability, the DOOSAN MYNX 5400/50II remains one of the most respected vertical machining centers in its class.
