PROBLEM TO BE SOLVED: To provide an ultrasonic machining device of high stiffness capable of efficiently transmitting a pressurizing load (pressurizing force) required for ultrasonic machining, and ultrasonic vibrations to work.SOLUTION: An ultrasonic machining device 10 includes: a base plate 30; a strut 40 raised on the base plate 30; a storage case 60 supported by the strut 40; an ultrasonic vibration generator stored in the storage case 60; and a horn 80 connected to the ultrasonic vibration generator through a cone 70, and exposed to the outside of the storage case 60. Between the strut 40 and the storage case 60, a first vibration accepting portion (for example, a height adjusting device 50) sharing a part of the vibrations of the horn 80 is provided. Between the strut 40 and the base plate 30, a second vibration accepting portion (for example, first and second columns 41 and 42) sharing the rest part of the vibrations of the horn 80 is provided. |
