KBT-11Z / KBT-11EZ

CNC Horizontal Boring & Milling Machines


FEATURES

  • 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.
  • Powerful heavy-duty cutting via high-torque 3-steps geared head.
  • Efficient chip management using a coil-type chip conveyer in the horizontal X axis as standard equipment.
  • High-accuracy indexing ensures standard rotary milling.
  • Standard Big-Plus dual contact system.
