DNM 4500 4th Generation
DNM 4500 4th Generation 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 1000x450 mm. The stroke is X 800 mm Y 450 mm Z 510 mm.
