The Doosan DNM 6700L is a vertical machining center (VMC) designed for high productivity and precision machining. It's known for its extensive list of standard features, making it a powerful and versatile option for various metalworking applications.
Features:
- Large Work Capacity: The DNM 6700L boasts a spacious table (1600 x 670 mm) and ample travels (X: 1500 mm, Y: 670 mm, Z: 625 mm) to accommodate a wide range of workpieces.
- High Performance Spindle: A 12,000 rpm spindle with 18.5 kW (25 hp) of power and 118 Nm of torque tackles tough materials efficiently. The BT40 spindle taper with a dual contact (Big Plus) spindle nose ensures rigidity and reduces vibration for improved machining accuracy.
- Fast and Precise Movement: Rapid traverse rates of 36 m/min (1417 ipm) on all axes allow for quick tool positioning and reduced cycle times. Fanuc AC servo drives and absolute position encoders guarantee precise movement and eliminate the need for axis limit switches.
- Automatic Tool Changer (ATC): A high-speed arm-type ATC with a 30-tool bi-directional magazine minimizes tool change times (1.3 seconds tool to tool) for increased productivity.
- Advanced Control System: The Doosan Fanuc i Series (0i-Pus) CNC controller offers a user-friendly interface and features like rigid-synchronized tapping, helical interpolation, and artificial intelligence contour control (AICC) for enhanced machining capabilities.
- Efficient Chip Removal: Twin-screw internal chip conveyors and a link-type external chip conveyor ensure efficient chip evacuation, minimizing downtime for chip removal.
- User-Friendly Design: The swiveling control panel, remote MPG (handwheel), and comprehensive work light system enhance operator comfort and control.
