DOOSAN DNM 750II VERTICAL MACHINING CENTER

Technical Description

This high-performance CNC machining center features an expansive work envelope with 64.2 inches of X-axis travel, 30 inches of Y-axis travel, and 25.6 inches of Z-axis travel, accommodating large and complex parts. The machine is equipped with a powerful 21 HP spindle motor capable of reaching speeds up to 12,000 RPM, ensuring efficient material removal and precision finishing. The spindle utilizes a CAT 40 (BIG PLUS) taper, providing superior rigidity and accuracy through dual-contact interface technology, which enhances tool life and minimizes deflection during heavy cutting operations. An automatic tool changer (ATC) with a 30-tool capacity streamlines production by reducing setup times and increasing versatility. Rapid traverse rates of 1,181 inches per minute on the X/Y axes and 945 inches per minute on the Z-axis enable swift positioning and improved cycle times. The machine weighs approximately 32,000 lbs and measures 196 inches in length, 118 inches in width, and 128 inches in height, offering robust stability and durability. The table measures 64.2 inches long by 29.9 inches wide and can support workpieces up to 3,306 lbs, making it suitable for demanding industrial applications. Additionally, the machine is equipped with through-spindle coolant at 1,000 PSI, optimizing chip evacuation and tool cooling for enhanced machining performance and surface finish quality.
