The difference between the ultrasonic cutting knife and the traditional cutting knife The problems of the traditional cutting knife The traditional cutting uses a knife with a sharp edge to press against the material to be cut. The pressure is concentrated at the cutting edge, the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bonds of the material are pulled apart and cut. Since the material is pulled apart by strong pressure and rigidity, the cutting edge of the cutting tool should be very sharp, and the material itself has to withstand relatively large pressure. The cutting effect is not good for soft and elastic materials, and it is more difficult for sticky materials. Advantages of Ultrasonic Cutting Knife When the ultrasonic cutting knife is doing ultrasonic vibration, the friction resistance is very small, and the material to be cut is not easy to stick to the blade. It has obvious cutting effect on frozen, viscous and elastic materials. It is especially effective for cutting food, rubber or objects that are inconvenient to apply pressure. At the same time of cutting, the cutting part has fusion function, and the cutting part can be sealed, which can prevent the loosening of the material to be cut (such as the flash of textile materials).
