Design of a Longitudinal-Bending Elliptical Vibration Ultrasonic Transducer with a Bent Horn
ActuatorsThe thin and straight horn of the ultrasonic transducer is located in the center of the thick transducer, so that the tool tip of the ultrasonic vibration turning tool holder cannot be located on the outermost side of the entire tool holder, which leads ...
