GROB G150

The GROB G150 is a 5-axis universal machining center with three linear axes (X, Y, Z) and two rotary axes (A and B) and a horizontal spindle position. It performs 5-sided machining and 5-axis simultaneous interpolation on complex parts, with working travels of 450 mm in X, 670 mm in Y and 665 mm in Z. Direct, absolute position encoders in all axes support a positioning accuracy of 0.006 mm.
