2021 DOOSAN MYNX5400-50 VERTICAL MACHINING CENTER

Technical Description

The 2021 Doosan MYNX5400-50 is a 3-axis vertical machining center configured with a BIG PLUS CAT 50 spindle taper for high-torque cutting of large steel, cast iron, and heavy alloy components. The machine shares the MYNX 5400 structural platform and provides 40.2 inches of X-axis travel, 21.3 inches in Y, and 20.8 inches in Z over a work table measuring 47.2 x 21.3 inches with an 800 kg (1,764 lb) maximum load. The CAT 50 spindle delivers 30 HP (22 kW) at a maximum speed of 6,000 RPM and 452.5 Nm of torque, making it well suited to heavy face milling, large boring operations, and deep-cavity mold work requiring high material removal rates in tough materials. The machine is controlled by a Fanuc 0i-MD CNC system with Siemens 828D and Heidenhain iTNC 530 available as options. A 24-tool ATC and through-spindle coolant support high-productivity extended programs. The -50 suffix designates the CAT 50 taper configuration, which trades higher spindle speed for substantially greater torque versus the standard CAT 40 variant. The MYNX5400-50's double-column structure provides superior thermal stability and rigidity. The overall footprint measures approximately 132 x 97 inches with a height of 118 inches and an installed weight of approximately 16,534 lbs (7,500 kg).
