The principle of ultrasonic cutting machine is completely different from traditional cutting. It uses ultrasonic energy to locally heat and melt the material to be cut, so as to achieve the purchase of cutting the material. Therefore, ultrasonic cutting does not require a shape edge, nor does it require a lot of pressure, and will not cause the edge of the material to be cut to collapse or be damaged. At the same time , due to the ultrasonic vibration of the cutter, the friction resistance is very small, and the material being cut is not easy to stick to the blade. Especially suitable for cutting viscous and elastic material, frozen material, such as food, rubber, etc.,or objects that are inconvenient to pressurize.
