DNM 750L II
DNM 750L II is a VMC supplied by DN Solutions(Doosan Korea). This machine is a 3-axis machining center with a C-frame structure in which the milling head moves up and down along the column (Z-axis), the saddle moves back and forth on the bed (Y-axis), and the table moves from side to side on the saddle (X-axis). The table is a rectangule, and the size is 2160X760 mm. The stroke is X 2160 mm Y 762 mm Z 650 mm.
