The New G150 Dominant in the Automotive Industry
With the newly developed G150, GROB rounds off the bottom
end of its universal machining center range. The G150 profits
from market dominance in the automotive industry due to the
modular G-series system, which has continuously defined the
bar for productivity and process safety.
