Ultrasonic cutting principle

Ultrasonic cutting completely different cutting machine principle and the traditional sense of the. Ultrasonic cutting principle is by the ultrasonic generator to convert the 50/60Hz current of 20, 30 or 40KHz power. Be converted into mechanical vibration of equal frequency, then the mechanical vibration through a set of can change the amplitude modulation device is transferred to the cutting knife. Cutting vibration energy is received to transfer to the cutting surface of the workpiece to be cut, in this region, the vibration energy is activated through the rubber molecules can open the molecular chain, the way of cutting material of rubber. This pair of viscous and elastic material, frozen material, such as food, rubber, or inconvenience plus pressure cutting objects, particularly effective. Ultrasonic cutting has a lot of advantages, it is in the cutting at the same time, a fusion effect in cutting parts. Cutting edge position is perfect, can prevent the material to be cut loose organization (such as textile material flash). The use of ultrasonic cutting machine can be extended, such as digging, digging, scraping paint, sculpture, strip and so on.

Two, the basic structure and characteristics of ultrasonic cutting

Ultrasonic cutting machine is a kind of equipment for cutting processing and utilization of wave energy, its biggest characteristic is not cutting edge. Or, instead of the traditional sense of the cutting edge. The traditional cutting is to use the tool with sharp edge, pressure to the material being cut. The stress is concentrated at the edge, the pressure is very big, exceeds the shear strength of the material being cut, material molecular binding is opened, it was cut. Because the material is strong pressure of rigid open, so the cutting tool edge should be very sharp, the material itself but also bear more pressure. Not good for cutting elastic material is soft, effect, more difficult for viscous materials.
