VMC Speeds up Cutting Times

June 13, 2018
Doosan's high-speed VMC offers a 25 HP spindle that features 87 ft-lb of torque.

The DNM 5700S, a high-speed version of the standard DNM vertical machining center, is engineered for high-speed cutting while also reducing non-cutting times, making this VMC ideal for high productivity shops.


Speed comes standard on the DNM 5700S thanks to a newly designed 15,000RPM directly-coupled 40 taper BIG-PLUS spindle. This 25 HP spindle features 87 ft-lb of torque, and accelerates from 0 to 15,000RPM in just 3.6 seconds. Additionally, rapid traverse rates were increased to 1,654 IPM in X and Y and 1,417 IPM in Z to keep cutting tools in the cut longer.


A wide cast frame with eight leveling positions has been optimized with 3D computerized analysis to improve rigidity and stability. The DNM 5700S also incorporates roller LM guideways on the X, Y and Z axis for speed and added rigidity (33%-44% more rigid than ball LM guideways). The 51.2 by 21.3 in. table holds a maximum weight of 1,764 lb.


Other standard features include a 30-tool magazine (with an available 40 and 60-tool servo-driven version). An Easy Operation Package (EOP) software provides operator convenience, while an oil-cooled spindle controls heat to minimize thermal issues. The DNM 5700S comes with a grease lubrication system that saves on maintenance costs and uses an eco-friendly coolant, eliminating the need for an oil skimmer.
