DN Solutions (formerly Doosan Machine Tools) introduces the DVF 4000, a smaller version of the company’s popular DVF family of vertical 5-axis machining centers. The DVF Series is made up of compact 5-axis CNC machines that are fully packaged to manage a customer’s diverse 5-sided or simultaneous 5-axis applications.
“The DVF 4000 is the perfect model for shops that want an integrated 5-axis solution for virtually any part that has required multiple operations or setups in the past,” said Andy McNamara, vice president of marketing and sales at DN Solutions America. “It allows them to step up in terms of productivity and quality without spending half a million dollars on a CNC machine tool.”
The DVF 4000 comes standard with a 15,000 r/min direct coupled spindle, powered by a 24.8 hp (18.5 kW) motor that generates 87.1 ft-lbs (118 Nm) of torque. A FANUC 31i-B5 Plus control makes full 5-axis simultaneous control possible, giving complete contouring capabilities. It features a 400 mm diameter built-in rotary table with a zero-backlash roller gear cam design for superior rigidity and speed. The rotary table is designed for ease of use and consummate work efficiency, minimizing interference as the part is machined. An eight- or twelve-pallet AWC (Auto Work Changer) provides additional productivity by offering up pallets to feed the machine for unattended machining.
Each DVF Series machine comes equipped with a 40-tool servo-driven automatic tool changer, giving the customer more tooling to tackle complex parts that have varying profiles. For even more versatility, 60- and 120-tool magazines are also available. The oil-cooled spindle controls heat to minimize thermal issues. A Z-axis thermal compensation feature collects real-time data from six sensors throughout the machine to automatically calculate compensation.
The DVF Series also incorporates roller LM guideways for speed and added rigidity. The machines are equipped with linear scales on the X, Y, and Z axes and rotary scales on the B and C axes for the most accurate positioning and repeatability.
“If you are using a 3-axis vertical with a retrofitted rotary table to avoid multiple operations or setups, the DVF 4000 provides a cost effective, purpose-built alternative that was carefully designed from the ground up for maximum productivity,” said McNamara. “Their compact footprint also enables installation in smaller shops where floor space is limited or comes at a premium.”
