GROB G350T

The GROB G350T is a 5-axis universal mill-turn machining center with three linear axes and two rotary axes. It supports 5-sided machining, 5-axis simultaneous interpolation and GROB TRAORI turning, and its horizontal spindle and tunnel work area allow long tools to be swiveled and machined without collision. It is intended for machining smaller parts in one setup.
