The parameters of ultrasonic transducer and variable amplitude rod are designed and optimized. the specific contents are as follows: in the first chapter, the application, productivity and processing process of soft magnetic Ferrite core in China are introduced. Secondly, eight typical deburring methods are compared, and the ultrasonic method is selected to remove the soft magnetic Ferrite core burr.
