5-Axis Machines Cut Diverse and Complex Shapes In One Setup
Automation options for DVF Series simultaneous 5-axis vertical machining centers from Doosan Machine Tools America save time and money by enabling shops to run production parts overnight and quickly switch over to prototype parts.

The space-saving DVF Series of vertical 5-axis machining centers from Doosan Machine Tools America (Pine Brook, NJ) is built for a wide range of 5-sided and simultaneous 5-axis applications. A Fanuc 31i-B5 CNC controller makes 5-axis simultaneous control (all axes feeding at once) possible, providing full contouring capabilities; and the cantilever-style table provides access to parts from a variety of angles.
The series comprises three machines:
DVF 5000. An 18,000 r/min CAT40/BIG PLUS taper spindle facilitates high-speed metal removal; and a 19.7-inch-diameter (500mm) B- over C-axis rotary table with a 24.8-inch (630mm) option. The table support holds over 880 pound and minimizes deflection. Absolute glass scales on XYZ axes and angular optical encoders on B and C axes ensure high-resolution positioning and repeatability.
DVF 6500. Same spindle, but with a 25.6-inch-diameter (650mm) A- over C-axis rotary table.
DVF 8000. Two versions: one with a 31.5-inch-diameter (800mm) rotary table, and a T model for turning operations.
All machines come with a 60-tool servo-driven automatic tool changer that can be expanded up to 120 tools, giving the customer more tooling to tackle complex parts that have varying profiles. Oil-cooled spindle controls heat to minimize thermal issues. Roller LM guideways increase speed and add rigidity. Compact footprint enables installation where floor space is limited or comes at a premium.
The machines can be customized with a diverse range of automation options – such as an auto workpiece changer (AWS) for the DVF 5000 – for lights-out operation. The AWC can be ordered in 4-, 6-, 8-, 10-, 12- and 24-pallet configurations. The DVF 6500 and DVF 8000 have similar automation options.
