KABUTO

KFN KABUTO FINELIVE CENTER with NUT – NC LATHE

Structured to keep cutting water away by means of air film resulting from rotation.
The product with light running torque is most suitable for fine machining or light metal working.
The replacement head enables cost reduction.

  • See Technical Specifications (HEAD LIST) for center head types.
  • See Technical Specifications  (ALLOWABLE LOAD & MORSE TAPAR) for revolutions per minute.
  • Type KFN has the same waterproof structure as that of type KFL.
  • Type KFN comes with the carbide center head A and then the center head ejecting drift DHN-1
    (while KFN-5 comes with the carbide center head 5A60° and DHN-2).
