Background
Ultrasonic processing is a processing method in which materials are removed by utilizing ultrasonic vibration of a tool, by utilizing the impact, polishing, hydraulic impact and the like of a long-term abrasive in a liquid medium with an abrasive or a dry abrasive, or by utilizing cavitation generated by the impact, polishing, hydraulic impact and the like, or by applying ultrasonic vibration to a tool or a workpiece in a certain direction, or by utilizing ultrasonic vibration to combine the workpieces with each other.
The ultrasonic transducer in the ultrasonic processing device is a core component of an ultrasonic vibration system.
