A variety of ultrasonic processing machines have been developed and manufactured to suit different purposes, and are proving very effective.

動に強いものであることが要求される。 This ultrasonic processing machine fixes a metal horn with a processing tool attached to the end face of a magnetostrictive vibrator or electrostrictive vibrator, and generates longitudinal vibration resonance while using a machining fluid containing abrasive grains. A machining tool is brought into pressure contact with a workpiece, and the hole is drilled by vibration of the tool in the vertical direction. Therefore, the machining tools used in this ultrasonic machining machine are required to be resistant to changes in machining pressure and vibrations because they directly contact the workpiece to perform machining.

あつた。 However, such conventional tools have a hollow interior even at the connection with the horn, so they are weak in strength and can easily break if the machining pressure is changed or the horn is vibrated. The problem was that it was easily damaged. Further, due to the presence of a cavity in the connecting portion of the horn, vertical vibrations are attenuated, resulting in problems such as requiring a long time to process.
