What is the Principle of Ultrasonic Blade Replacement Cutting Knife?

Ultrasonic cutting knife uses the energy of ultrasonic waves to cut the local vibration of the material being cut, thereby achieving the purpose of material cutting. Traditional cutting uses sharp edged tools to press the material being cut, with pressure concentrated at the cutting edge. The pressure is very high, exceeding the shear strength of the material being cut, and the molecular bonds of the material are pulled apart, resulting in cutting. Ultrasonic cutting has a great advantage, which is that it has a fusion effect at the cutting site while cutting, and the cutting site is perfectly sealed to prevent the loosening of the material tissue being cut. Therefore, ultrasonic cutting does not require sharp cutting edges, does not require a lot of pressure, and will not cause edge breakage or damage to the material being cut. When the cutting blade vibrates with ultrasonic waves, the frictional resistance is particularly small. The high-frequency signal generated by the ultrasonic vibration system is transmitted to the ultrasonic transducer, converted into sound waves, and transmitted to the ultrasonic cutting edge through the amplitude lever, converting the sound wave energy into mechanical vibration energy to achieve the function of cutting vibration. By using the cutting edge of the cutting blade, the ultrasonic energy is concentrated and input to 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 decreases. At this time, as long as a small cutting pressure is applied, the purpose of material cutting can be achieved.
