DOOSAN MV 4020 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a robust work envelope with X-axis travel of 40.2", Y-axis travel of 20.1", and Z-axis travel of 24.6", supported by a large table measuring 47.2" by 19.7". The table-to-spindle nose distance ranges from 5.9" to 30.5", allowing flexible machining of tall or thick workpieces. It utilizes a CAT-40 spindle taper with a powerful 20 HP spindle motor capable of speeds up to 8,000 RPM, ensuring efficient material removal and surface finish quality. The machine is equipped with a side-mount tool changer holding 30 tools for uninterrupted multi-tool machining cycles. Rapid traverse rates are 1181 IPM for the X and Y axes and 945 IPM for the Z axis, while cutting feed rates range from 0.04 to 472 IPM, offering a wide performance envelope for various machining tasks. Structurally, the machine is sizable with approximate dimensions of 130" length, 105" width, and 110" height, and a substantial weight of 15,500 lbs, indicative of a stable and vibration-resistant design suitable for precision milling. This configuration supports complex and high-throughput machining operations for aerospace, automotive, and general manufacturing industries requiring high rigidity, accuracy, and automation for medium to large parts.
