High-Speed VMC Reduces Non-Cutting Time
IMTS 2018: Doosan Machine Tools’ DNM 5700S VMC is designed to cut at high speed and to reduce non-cutting time.
Doosan Machine Tools’ DNM 5700S is a high-speed version of the DNM VMC that is designed to reduce non-cutting time.
A 25-hp, directly-coupled, 40-taper Big-Plus spindle features 87 foot-pounds of torque and accelerates from 0 to 15,000 rpm in 3.6 sec. Rapid traverse rates have been increased to 1,654 ipm in the X and Y axes and to 1,417 ipm in the Z axis.
A wide cast frame with eight leveling positions and roller LM guideways on the X, Y and Z axes improve machine rigidity and stability. The VMC also features 3D computerized analysis. Its 51.2" × 21.3" table can hold a maximum weight of 1,764 lbs.
The machine features a 30-tool magazine, with 40- and 60-tool, servo-driven versions available. Easy Operation Package software contributes to ease of use, while an oil-cooled spindle controls heat. The machine comes with a grease lubrication system designed to reduce maintenance costs. It uses a coolant that is intended to eliminate the need for an oil skimmer.
