DOOSAN DNM-750 VERTICAL MACHINING CENTER

Technical Description

The Doosan DNM-750 Vertical Machining Center is a high-performance CNC machine designed for precision machining of medium to large workpieces. It features a robust 3-axis configuration with X-axis travel of 64.2 inches, Y-axis travel of 30 inches, and Z-axis travel of 25.6 inches, providing ample workspace for demanding applications. The machine is powered by a 21 HP spindle capable of reaching 12,000 RPM, delivering high-speed performance and efficient material removal. Equipped with a CAT 50 Big Plus spindle system, it ensures excellent rigidity, thermal stability, and compatibility with heavy-duty tooling. The automatic tool changer (ATC) supports 30 tools, enhancing productivity in complex machining operations. The table measures 64.2 inches in length and 29.9 inches in width, with a maximum load capacity of 3,306 lbs, making it suitable for large and heavy components. The machine’s rapid traverse rates are 1,181 IPM on the X-axis and 945 IPM on Y/Z axes, while the cutting feedrate reaches 590 IPM, ensuring fast and accurate machining. With a repeatability of ±0.000080 inches, the DNM-750 delivers exceptional precision. The spindle offers 122 ft-lbs of torque (30-minute rating) and accelerates from 0 to 12,000 RPM in just 5.6 seconds. The machine requires 45 kVA power at 205–235 volts, three-phase, and weighs 31,680 lbs. Its compact footprint (151 x 135 x 125 inches) and advanced features make it ideal for high-volume production and precision manufacturing environments.
