Problems solved by technology

However, the ultrasonic vibration of traditional one-dimensional ultrasonic machining is only along the processing depth direction, which is only suitable for copy-type forming processing. It is difficult to manufacture ultrasonic machining tools with complex shapes, and the tool head wears quickly, which affects the processing accuracy and efficiency.
