2010 DOOSAN MV4020 VERTICAL MACHINING CENTERS

Technical Description

The 2010 Doosan MV4020 is a 3-axis vertical machining center offering a generous work envelope suited to medium and large part machining. The machine provides 40.2 inches of X-axis travel, 20.1 inches in Y, and 24.6 inches in Z, with a work table measuring 47.2 x 19.7 inches capable of supporting substantial workpiece weights. The CAT 40 spindle delivers 20 HP and reaches a maximum speed of 8,000 RPM, controlled by a Fanuc 21i-M or Fanuc 0i-MC CNC system. A 24- to 30-tool automatic tool changer supports complex multi-operation jobs in a single setup. The MV4020 is built on a rigid cast iron structure with box-way guideways providing excellent vibration damping under heavy cutting loads in steel, cast iron, and aluminum. Its broad table and deep Z-axis travel make it well suited to fixture plates, large castings, and tooling plates. Flood coolant is standard, with through-spindle coolant available on equipped units. The MV4020 was a widely adopted machine across North American and European contract shops during the early 2000s and represents a versatile general-purpose platform from the Doosan/Daewoo transition era. Overall machine dimensions are approximately 128 x 126 inches with an installed height of 118 inches and a total weight of approximately 15,500 lbs, reflecting the heavy casting construction that contributes to its machining stability.
