Description

technical field [0001] The invention belongs to the technical field of ultrasonic processing, and relates to a double-rod giant magnetostrictive ultrasonic vibration device. Background technique [0002] Rotary ultrasonic machining is based on traditional ultrasonic machining, with ultrasonic mechanical vibration added, which can effectively reduce cutting force, reduce tool wear, improve material removal efficiency, and improve processing quality, especially for difficult-to-machine materials. [0003] In the field of ultrasonic machining technology, the main ultrasonic transducer materials used are piezoelectric ceramics and giant magnetostrictive materials. The power density of piezoelectric ceramics is relatively small, and there are deficiencies such as overheating failure and fragility. Giant magnetostrictive materials have the advantages of large magnetostrictive strain, high energy density, and fast response speed, and are the research direction of high power and la...
