DMG MORI CMX 70 U 5-AXIS CNC milling centre

DMG MORI CMX 70 U 5-AXIS CNC milling centre was manufactured in 2018 in Japan. The universal machining centre bed is supported at 4 points and is made of mineral casting, which perfectly dampens vibrations and ensures good chip and heat removal from the workspace.

Equipped with a SIEMENS 840D SL 5-axis milling centre allows machining a workpiece of maximum weight 350 kg on the 800 x 620 mm rotary table. The machine operates in five axes: X,Y,Z and B, C. The axis feed rates are 750 mm (X axis), 600 mm (Y axis), 520 mm (Z axis), -10°/+95° (rotary B axis) and 360° (rotary C axis).

The CNC milling machine spindle operates at speeds from 20 to 12000 rpm and is equipped with a SK40 toolholder. The CNC milling machine also features a chain tool magazine with double gripper, accommodating up to 30 tools of 300 mm length and 8 kg weight. The Renishaw Touch Probe-Kit measurement system ensures the best positioning accuracy and repeatability during machine use. The total weight of the milling centre is 7800 kg.
