The principle of an ultrasonic cutter is completely different from that of a conventional one. The principle of ultrasonic cutting is to convert 50/60 Hz current into 20, 30 or 40 KHz electric energy through an ultrasonic generator. It is converted into mechanical vibration of the same frequency, and then the mechanical vibration is transmitted to the cutting blade through a set of amplitude modulator devices that can change the amplitude. The cutter transfers the received vibrational energy to the cutting face of the workpiece to be cut, in which the vibrational energy is cut by activating the molecular energy of the rubber molecule and opening the molecular chain. 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 in that it has a fusion at the cutting point while cutting. The cutting site is perfectly sealed to prevent loose tissue (such as textile material flash). The use of ultrasonic cutting machines can also be extended, such as digging holes, shovel digging, scraping paint, engraving, slitting and so on.
Ultrasonic cutting machine is a kind of equipment that uses wave energy for cutting. Its biggest feature is that cutting does not use cutting edge. Or, instead of the cutting edge in the traditional sense. Conventional cutting uses a sharp-edged tool to press against the material being cut. This pressure is concentrated at the cutting edge, and the pressure is very large, exceeding the shear strength of the material being cut. The molecular combination of the material is pulled apart and cut. Since the material is pulled hard by the strong pressure, the cutting edge of the cutting tool should be very sharp, and the material itself must withstand relatively high pressure. It is not good for soft and elastic materials, and it is more difficult for viscous materials.
