HAAS UMC-750 CNC vertical machining center

HAAS UMC-750 CNC vertical machining center was built in 2015 in the United States by HAAS AUTOMATION, INC. The machine, distinguished by the use of many modern components, is an excellent choice for 5-axis, precision machining of workpieces with complex geometries. Workpieces weighing up to 300 kg are machined on a large trunnion table using a reliable liquid -cooled spindle. The work table with classic T-slots and a pilot bore tilts from +120° to –35°, providing easy access to the workpiece and a large workspace. The UMC 750 CNC machining center is offered with a wide range of equipment, which includes, among others, an intelligent CNC control and a multi-stage coolant pump. The total weight of the machine is approximately 7000 kg.
