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.
