Kuraki KBT-11Z

High Rigidity Machine Reinforced for Heavy-Duty Workpieces.

  • The column traverse allows for heavy-duty workpieces and improves accessibility to the workpiece.
  • Standard coil type chip conveyor provides parallel to the X axis capable of effective swarf disposal and cutting fluid disposal
  • Y-axis (spindle vertical) travels 1800 mm(70.87”)and table size 1400 × 1750 mm(55.12”×68.90”), higher and bigger than KBT-11W.A
  • Powerful heavy-duty cutting via high-torque 3-steps geared head
