Highlights

DMU 340 Gantry

Precision

  • Maximum accuracy through water-cooled feed drives
  • Band filter unit with 2,500 l as standard
  • Highest long-term accuracy due to cooled linear guideways and active spindle growth control.

Performance

  • High dynamics with feed speed up to 1,574.8 ipm
  • High feed power up to 11,240 lbf
  • Biggest spindle range in the market: powerMASTER motor spindle with up to 737.6 ft lb and torqueMASTER gear spindle with 1,327.6 ft lb

Efficiency

  • Lower energy consumption through intelligent needs-based power units.
  • Gantry design with vertically moving cross beam with hydraulic weight compensation.
  • Fast innovative wheel type magazine with up to 243 tools with minimized footprint. 

Highest rigidity and dynamics up to 16.4 ft/s²

  • Thermosymmetrical construction
  • 3-point support with an inherently stiff machine bed, no foundation required
  • High temperature stability standard with positioning accuracy down to 0.38 µin
  • Position accuracy down to 0.30 µin with accuracy pack option
  • Short and continuous throat depth of milling head (no ram design)
