Description of the DOOSAN MYNX 6500/50 milling center operation

The machine tools are cooled by a spindle and a spray system with coolant. The machine drive is transmitted from the engine (power 18.5 kW) through a two-stage gear transmission. Feeds and revolutions are smoothly changed by means of inverters. The Teo-Step (two-stage) gearbox generates extremely high torque for a wide range of heavy-duty machining. The Big Plus system allows for simultaneous double contact of the tool holder on the conical side and the spindle face.
