ULTRASONIC VIBRATION CUTTING TOOL

摘要

PROBLEM TO BE SOLVED: To improve machining accuracy and cutting performance. SOLUTION: The ultrasonic vibration cutting tool 1 comprises a resonator 2 mounted on a driving shaft 4 of a driving device for a machine tool, to which the rotation driving force of the driving device and ultrasonic vibration generated by a sound source (a vibrator) are transmitted via the driving shaft 4, and a cutter part 3 provided on the resonator 2. The resonator 2 has a coaxially formed insertion hole 6 into which the driving shaft 4 is inserted. The driving shaft 4 is fitted into the insertion hole 6 in adhesion state with shrink fitting or expansion fitting.
