The basic composition of an ultrasonic cutting machine is an ultrasonic transducer, an horn, a cutting knife (tool head), and a driving power supply. The ultrasonic drive power converts the mains electricity into high frequency and high voltage alternating current, which is output to the ultrasonic transducer. The ultrasonic transducer is actually equivalent to an energy conversion device, which can convert the input electrical energy into mechanical energy, that is, ultrasound. Its manifestation is that the transducer stretches back and forth in the longitudinal direction. The frequency of the telescopic movement is equal to the frequency of the high-frequency alternating current supplied by the driving power supply. The role of the horn is to fix the entire ultrasonic vibration system, and the other is to amplify the output amplitude of the transducer. The cutting knife (tool head) further amplifies the amplitude and focuses the ultrasound. On the other hand, it outputs ultrasonic waves, and uses the similar cutting edge of the cutting knife to concentrate the ultrasonic energy into the cutting part of the material to be cut. Under the action of huge ultrasonic energy, this part instantly softens and melts, and its strength drops greatly. At this time, as long as a small cutting force is applied, the purpose of cutting the material can be achieved.
