G8

Gantry type VMC > G Series

5-Axis CNC Machine
The G8 design is based on an advanced gantry construction giving the most powerful structure to achieve the best working conditions when machining the most complex work pieces.

The powerful 5 axes simultaneous machining is provided by high dynamics from tool motion (3 axes) and working piece motion (2 axes). Both rotary axes in the table are driven by built-in motors with high torque!
