OKUMA MA-50 HB CNC horizontal machining center

OKUMA MA-50 HB CNC horizontal machining center was built in 2000 by the Japanese corporation OKUMA. The machine, designed for advanced machining of workpieces with a maximum weight of 800 kg, is distinguished by its high reliability, efficiency and precision. The machining process is performed fully automatically by means of a high-speed spindle and cutting tools taken from a 40-position magazine. What’s more, the automatic pallet exchange system allows for simultaneous loading and unloading of workpieces during the machining process, reducing machine downtime to a minimum. The MA-50 HB CNC machining center is offered with extensive equipment, including among others a rotary table and an advanced CNC control with an intuitive interface. The total weight of the machine is 21000 kg.
