GILDEMEISTER MF TWIN 65 Y CNC lathe

GILDEMEISTER MF TWIN 65 Y CNC lathe built in 1999 in Germany allows for fully automated production processes while maintaining high accuracy and low operating costs. The machine distinguished by its extensive machining capabilities, thanks to its sturdy design, extensive equipment and focus on high productivity, is ideal for any production facility, even during the most demanding challenges.

The MF TWIN 65Y CNC turning centre performs precision machining of metal workpieces with a maximum diameter of 200 mm, using reliable tools located in two 12-position tool heads (upper and lower). Workpiece turning takes place inside a large work area equipped with a rigid bed inclined by 45° and an integrated chip conveyor designed to keep the work area clean by constantly removing the chips into a special container located next to the machine. The GILDEMEISTER MF TWIN 65 CNC dual-spindle lathe is also equipped with, among others, a workpiece conveyor, IRCO SiMag bar feeder, Y axis and additional tooling. The total weight of the machine is approximately 6500 kg.
