Kuraki KBF-15

Ultra-Large Machine for Machining Massive and Heavy Workpieces.

  • An optional rotary table is available for multi-face machining.
  • Reducing the X- and Y-axis travels can attain better cost performance than a conventional floor type machine.
  • Capable of various customizations to meet your requirements
