DNM 400A VMC

December 01, 2010

Doosan Infracore introduces the DNM 400A vertical machining center, designed for high productivity with precision tolerances, and built to fit the most crowded shop floors — and all at a price below $70,000. The DNM 400A's rugged, one-piece casting is strategically ribbed to prevent distortion during heavy or interrupted cuts.

Fine grain Meehanite is selected for its superior dampening characteristics and ability to dissipate heat. Widely spaced linear guideways give excellent support to the saddle in all locations, regardless of the table's load distribution. Each guideway is induction hardened and precision ground. Rapid traverses are 1,181 ipm along all three axes.

Powering the DNM 400A is a 15-hp spindle motor that drives ISO#40 taper tools at speeds up to 8,000 rpm, while delivering 52 ft. lbs of torque. The cartridge-type spindle is supported by precision-class, permanently-lubricate bearings. A heavy-duty drive belt eliminates slippage, reduces vibration, and contributes to thermal stability. A 20 station, double-arm ATC changes tools in a quick 1.3 seconds.

The Big Plus dual-contact tooling system creates full contact along the spindle taper and the toolholder flange. This assures maximum rigidity for greater precision and longer tool life. Both Big Plus and standard tool holders can be mounted at any ATC station with no need for special adaptors. The 86.7" x 87.2" footprint is perfect for buildings with standard 8' x 8' doors. Maximum part size is 25.0" x 17.1" x 20.1" and 881 lbs.
