2020 Doosan DVF-6500 CNC Vertical Mill

The Doosan DVF-6500 is a simultaneous 5-axis vertical machining center with a reputation for rigidity and repeatable accuracy that has made it a staple in aerospace, medical, mold, and precision job-shop environments. This 2020 example pairs a trunnion-style tilting rotary table - A-axis tilt of +/-120 deg and full 360 deg C-axis rotation - with X/Y/Z travels of 29.5 x 30.9 x 23.6 inch (750 x 785 x 600 mm) and a 650 mm diameter x 600 mm table that accepts workpieces up to 840 mm in diameter and 500 mm tall at up to 2,204 lbs. Power comes from an 18,000 RPM spindle rated at 22 kW and 118 N-m through a CAT40 BIG-PLUS taper, fed by a 3 MPa (435 psi) through-spindle coolant system for deep-pocket and small-diameter tooling. The linear axes move at 45 m/min rapids for true simultaneous contouring, and the machine runs a Fanuc Series 31i-Model B5 control. It is equipped with a Renishaw spindle probe, Renishaw laser tool setter, LNS mist collector, and chip conveyor - a turnkey 5-axis package ready for single-setup, five-sided machining.

Compared to Doosan's earlier VC 630/5AX 5-axis machining center, the DVF-6500 is a meaningful step forward rather than just a newer badge. The DVF platform introduced a fully integrated, one-piece 5-axis design with a roller-gear cam driven trunnion for higher rotary rigidity and faster, backlash-free indexing than the older VC-series drive. Buyers gain a higher-speed 18,000 RPM spindle, faster rapids, a more accessible work envelope, and the current-generation Fanuc 31i-B5 control in place of the older i-series controls - improvements that translate into shorter cycle times, better surface finish on contoured work, and the confidence to hold tight tolerances setup after setup. For a shop stepping up to full simultaneous 5-axis, this DVF-6500 delivers modern capability at a used-machine price.
