Kuraki KBF-15H

Ultra-Large Machine for Machining Massive and Heavy Workpieces.

  • X-axis travel 4000~10000 mm(157.48”~393.70”) and Y-axis travel 2000~3000 mm(78.74”~118.11”), is optimum for machining a heavy-duty and huge workpiece which cannot be machined on a table-type machine
  • Employment of a ram-type spindle head enables both the spindle head and the boring spindle to move together and improves accessibility to the workpiece.
  • The optional auto up/down operator platform improves the machine operation.
