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.
