GILDEMEISTER MF twin 65 CNC lathe

GILDEMEISTER MF twin 65 CNC lathe was built in 2000 in Germany by GILDEMEISTER Drehmaschinen GmbH. This extremely efficient machine is used for precision machining of workpieces with a maximum diameter of 200 mm. The machining process is performed inside a large work space, by means of two spindles and tools taken from two 12-position turrets. This solution maximises production efficiency by enabling simultaneous workpiece machining on both spindles. What’s more, any vibration or oscillation is eliminated by a rigid bed, guaranteeing high process stability even during the most intense challenges. The MF twin 65 CNC turning center, including the control cabinet, weighs approximately 6500 kg.
