There are 3 automatic compensation systems : column vertical position, head-stock center of gravity and bending of the RAM.
X axis has a rack-pinion system with 2 motors and 2 pinions for backlash elimination, while Y axis has a fixed ball screw with rotary nut, able to reach rapid feed movements without vibrations.
Thanks to the big travels, X up to 40.000 Y up to 10.000 Z+W up to 3400 and spindle drive 100 kW in combination with the rotary tables up to 175 ton capacity, very big size and complex work-pieces can be machined in just one set up.
As in rest of models, a wide range of attachments can be used as automatic milling- facing heads, probes, ATC, AAC, rotary tables, etc turning into a multitask boring-machining center with up to 10 or more controlled axes.
