KBT-13A / KBT-13EA / KBT-15A

CNC Horizontal Boring & Milling Machines


FEATURES

  • Ultimate solution for high rigidity resulting from large-diameter pretensioned ball-screws and robust square slideway construction on each axis.
  • Designed for heavy load work and easy part accessibility with column Z axis traverses.
  • Efficient chip management using a coil-type chip conveyer in the horizontal X axis as standard equipment.
  • High torque allow for powerful and heavy duty cutting.
  • High-accuracy indexing ensures standard rotary milling.
  • Standard Big-Plus dual contact system.
