Abstract
The present invention provides an ultrasonic oscillation machining apparatus wherein accurate oscillation machining can be attained using a small vertical ultrasonic oscillating element which oscillates with a high frequency. The ultrasonic oscillation machining apparatus comprises a wide oscillating body divided into a plurality of units by one or more slits formed in said wide oscillating body with opposite end portions left thereon, a plurality of vertical ultrasonic oscillating elements secured to one end faces of said individual units of said wide oscillating body for producing vertical oscillations of such a frequency that said opposite end portions of said wide oscillating body are positioned at loop portions of oscillations of the wide oscillating body, and a bite provided at one of said end portions of said wide oscillating body which is positioned at one of the loop portions of oscillations of said wide oscillating body. The bite is driven with a high output power by vertical oscillations composite of oscillations produced by the individual vertical ultrasonic oscillating elements.
