The principle and application of ultrasonic cutting machine

　　Ultrasonic slitting machine is a device that can achieve accurate slitting. It is widely used in various fields such as food, medicine, cosmetics, etc., such as the cutting of bread, chocolate, meat, vegetables and other foods, as well as the cutting in surgical procedures. So what is its principle? How is it applied?

　　Ultrasound refers to sound waves with frequencies higher than 20 kHz, which cannot be heard in the air. The ultrasonic cutting machine utilizes the high-frequency vibration principle of ultrasonic waves to achieve the effect of shearing by frictional vibration on the material through the blade edge.

　　The specific principle is as follows:

　　The ultrasonic system consists of a controller, an oscillator, and a vibrating cutting blade. The controller can adjust the frequency, amplitude, and duration of the ultrasonic vibrator. The oscillator converts electrical energy into weak high-frequency mechanical energy and sends it to the vibrating blade to generate high-frequency vibration. When cutting with a high-frequency vibration knife, the material is placed above the oscillator, and the vibration knife generates high-frequency vibration on the surface of the material, forming a cutting effect. Due to the minimal heat generated by ultrasonic vibration during material reduction, it does not affect the quality of the material.
