What is the X-axis travel of the GROB G300?

600 mm, per Machining center G300 (grobgroup.com).

GROB G300

The G300 is a modular machining center built by GROB for flexible series production, and is the smallest size in the G-series. Its linear axes travel 600 mm in X, 770 mm in Y and 810 mm in Z, with maximum axis speeds of 95/45/100 m/min. Motion axes are split into tool-side and part-side groups, and the machine accepts a range of motorized spindles, tilting rotary tables and loading systems.
