Doosan Machine Tools' DVF Series of compact 5-axis machining centers is built for a wide range of 5-sided and simultaneous 5-axis applications. DVF machines are fully loaded to meet customer needs for cutting diverse and complex shapes in one setup. The FANUC 31i-B5 CNC controller makes full 5-axis simultaneous control (all axes feeding at once) possible, giving full contouring capabilities.
The DVF 5000 is equipped with a CAT40/BIG PLUS® taper 18,000 r/min spindle, which facilitates high speed metal removal. The DVF 5000 features a 19.7" (500mm) diameter B- over C-axis rotary table with a 24.8" (630mm) option. The machine table is an integrated cantilever style full 5-axis table, which allows for the machining of parts from a variety of angles.
Built-in table support holds a maximum weight of over 880lbs and minimizes any table deflection. The rotary table is designed for user friendliness and consummate work efficiency, minimizing interference as the part is machined. Absolute glass scales on XYZ axes and angular optical encoders on B and C axes ensure high resolution positioning and repeatability.
The DVF 6500 has the same spindle as the DVF 5000 but is designed with an integrated 25.6" (650mm) diameter A- over C-axis rotary table. Even larger is the new DVF 8000 version, which comes with a 31.5" (800mm) diameter rotary table. There will also be available a special T model of the DVF 8000 that is capable of turning operations., slated for release later in 2020.
Each DVF machine comes 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. An oil cooled spindle controls heat to minimize thermal issues. The DVF Series also incorporates roller LM guideways for speed and added rigidity. Their compact footprint enables installation where floor space is limited or comes at a premium.
These vertical 5-axis machining centers can be customized with a diverse range of tailored options that provide automation and convenience features that make them ideal for unmanned machining. One example is an optional/retrofittable AWC (Auto Workpiece Changer) for the DVF 5000, which gives you lights out machining capability. The AWC can be ordered in numerous pallet configurations: 4, 6, 8, 10, 12 and 24. The DVF 6500 and DVF 8000 models also come with their own automation options.
"The DVF Series is a perfect fit if you're trying to minimize setups, run production parts overnight or switch over to prototype parts quickly," said Jim Shiner, Director of Sales and Marketing at Doosan Machine Tools America.
