Abstract

See full text

The handpiece-type high-frequency vibration apparatus includes a roughly cylindrical housing 10 configuring a handpiece, a holding member 11, a tool 12, a controller 20 and an excitation device 21. In a non-contact state before the tool 12 is brought into contact with an object, the controller 20 drives the excitation device 21 so as to vibrate the tool 12 at an added frequency fp for which a predetermined frequency fs is added to a first resonance frequency fr1 of the tool 12. In a cutting state where the tool 12 is in contact with the object by a load that enables cutting of the object by the tool 12, the controller 20 controls drive of the excitation device 21 such that a third resonance frequency fr3 of the tool 12 increases and coincides with the added frequency fp, and increases a vibration frequency of the tool 12.
