OKUMA MA-600HII CNC Milling Centers

OKUMA MA-600HII CNC machining center was built in 2012 by the Japanese brand OKUMA Corporation. This highly efficient machine is used for advanced workpiece machining in 4 axes. The machining process is performed fully automatically inside a large working area by means of precision cutting tools and a reliable high-speed spindle. The automatic pallet changing system allows workpieces to be loaded and unloaded simultaneously during machining, reducing machine downtime to a minimum. The extensive equipment also includes, among others, a capacious tool magazine and an intelligent CNC controller with an intuitive interface. The MA-600HII CNC horizontal machining center weighs 24500 kg.
