The Doosan DNM 750/50 II is a vertical machining center (VMC) designed for high-precision machining of medium to large workpieces. It's a powerful and productive machine that is well-suited for a variety of applications in the metalworking industry.
Here are some of the key features and specifications of the Doosan DNM 750/50 II:
-
Large Travels: With travels of 1630 mm (64.2 in) on the X-axis, 762 mm (30 in) on the Y-axis, and 650 mm (25.6 in) on the Z-axis, the DNM 750/50 II can handle a wide range of workpiece sizes.
-
Powerful Spindle: The machine features a BIG PLUS CAT50 spindle with a maximum speed of 12,000 rpm and a torque of 165.5 Nm (122 ft-lbs). This allows for heavy-duty machining operations and the use of a wide variety of cutting tools.
-
High Rigidity: The DNM 750/50 II is built with a rigid construction that minimizes deflection during machining. This helps to ensure accuracy and repeatability.
-
Fast Rapid Traverse Rates: The machine's rapid traverse rates of 30 m/min (1181 in/min) on the X and Y axes and 24 m/min (945 ipm) on the Z-axis help to reduce cycle times and improve productivity.
-
Fanuc Oi-M Control: The DNM 750/50 II is equipped with a Fanuc Oi-M control, which is known for its user-friendly interface and powerful features. The control also includes DN Solutions (formerly Doosan Machine Tools) Easy Operation Package (EOP) for additional functionality.
-
Through-Spindle Coolant: The machine has through-spindle coolant capability, which delivers coolant directly to the cutting tool. This helps to improve chip evacuation and tool life.
-
Automatic Tool Changer (ATC): The DNM 750/50 II comes with an automatic tool changer with a capacity of 30 tools. This allows for quick and easy tool changes, which helps to reduce setup times.
-
Other Standard Features: The machine also includes a number of other standard features, such as a dual chip auger system, a spindle chiller, and pre-wired Renishaw probing.
Overall, the Doosan DNM 750/50 II is a versatile and powerful VMC that is well-suited for a variety of metalworking applications. Its large travels, powerful spindle, and high rigidity make it a good choice for machining medium to large workpieces. The Fanuc Oi-M control with EOP package provides ease of use and advanced functionality, while the standard features such as through-spindle coolant and automatic tool changer help to improve productivity.
