2018 DOOSAN VM750 VERTICAL MACHINING CENTER

Technical Description

The 2018 Doosan VM750 is a 3-axis die and mold vertical machining center built around an ISO 50 gear-drive spindle for heavy-duty cutting of large steel and cast iron mold components. The machine provides 59.1 inches of X-axis travel, 29.5 inches in Y, and 31.5 inches in Z over a work table measuring 63.0 x 31.5 inches with a maximum table load of 6,614 lbs (3,000 kg). The ISO 50 spindle delivers 20 HP continuous (25 HP peak) at a standard maximum speed of 6,000 RPM, generating up to 587.6 Nm of torque through the two-stage gearbox for large-diameter face milling and heavy boring operations. A built-in 12,000 RPM motorized spindle is available as an option for finishing applications requiring higher surface speeds. The Fanuc 31i-A CNC control is standard, with Siemens 840D sl and Heidenhain iTNC 530 available as options. A 30-tool ATC (expandable to 40) and through-spindle coolant support extended production programs. The VM750's thermally stable casting and oversized guideways maintain accuracy over long cutting cycles in hardened P20, H13, and S7 tool steels. Rapid traverse rates of 20 m/min on all axes reflect the machine's optimization for heavy material removal rather than high-speed light cutting. The machine occupies a footprint of approximately 194.0 x 193.0 inches, stands 139.6 inches tall, and weighs approximately 30,864 lbs (14,000 kg).
