X.mill 1680 • 1890

Rigidity, maximum precision and cost-effective operation make this proven series even more powerful
Travel X-axis

  • Extra wide cast-iron frame with heavy ribbing minimizes vibrations, resonance and torsion to ensure maximum accuracy and optimum surfaces of the part
  • Extra-wide rectangular Y axis guideways ensure superior rigidity during heavy chip removal operations and allow machining of large and heavy parts
  • Extraordinary table load capacity up to 6610 lbs
  • All guideways are ground, hardened and protected by premium stainless steel covers
  • Large, preloaded ball screws are driven directly by the servo motors
  • a powerful spindle motor provides 34 Hp to ensure adequate power reserves
  • Easy access and reachability of the machine table were the focus during the design of the machine frame and work space in order to reduce down-times to a minimum
  • Includes chip conveyor
  • The chip tray is easily accessible and includes a powerful chip flushing system
  • A blow-out and coolant gun are within reach of the operator for quick and easy cleaning of the workspace and the workpieces
  • Automatic central lubrication for low maintenance is standard
  • A spindle blow-out system protects the tool mount from chips and coolant
