Ultrasonic cutting knife, also known as ultrasonic cutt […]

Ultrasonic cutting knife, also known as ultrasonic cutting machine, is a kind of ultrasonic equipment specially used for cutting, and it is one of the important categories of ultrasonic applications. Mainly used for cutting rubber, synthetic fabrics, cloth, plastics, food, etc.
The principle of ultrasonic cutting is completely different from cutting in the traditional sense. Ultrasonic cutting uses the energy of an ultrasonic transducer to heat and melt a part of the material to be cut to achieve the purpose of cutting the material. Therefore, ultrasonic cutting does not require a sharp edge, nor does it require a lot of pressure, and will not cause chipping or breakage of the material being cut. At the same time, because the cutting knife is vibrating ultrasonically, the friction resistance is very small, and the material to be cut is not easy to stick to the blade. This is particularly effective for cutting viscous and elastic materials, frozen materials such as food, rubber, etc., or objects that are inconvenient to apply pressure. Ultrasonic cutting also has a great advantage, that is, it has fusion at the cutting part while cutting, and the cutting part is perfectly sealed without causing flashing of textile materials. The use of ultrasonic cutting knife can also be expanded, such as digging holes, shoveling, scraping paint, carving, etc.
The ultrasonic cutting knife is composed of transducer, horn, tool head (knife head), and driving power supply. The whole composed of transducer, horn and tool head is also called the complete machine.

From the cutting method, it can be divided into knife type ultrasonic cutting and chopping board type ultrasonic cutting
