CNC Horizontal Boring & Milling Machine
KURAKI – KBT-11EZ
■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
■Spindle speed 4500 min-1: Top of the class in this industry
■Employment of cooled ball screws achieves rapid traverse rate 18 m/min(708.66”/min)and cutting feedrate 12 m/min(472.44”/min)
■Powerful heavy-duty cutting via high-torque 3-steps geared head
