The principle of both
Laser Cutting Principle
Laser cutting is one of the thermal cutting methods. The principle of laser cutting is to use a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time use a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving cutting of the workpiece.
Ultrasonic cutting principle
The principle of ultrasonic cutting is to transfer the ultrasonic energy generated by the ultrasonic transducer to the horn, which then amplifies the energy and transmits it to the cutting blade to drive the cutting blade to vibrate at a high frequency. Under the action of the huge ultrasonic energy, the cutting position softens and melts instantly, and the strength is greatly reduced. Only a small amount of force is required to achieve the purpose of cutting the material.
Advantages
Laser cutting
As a new processing method, laser processing has been widely used in the leather, textile and clothing industries for its advantages of precise and fast processing, simple operation and high degree of automation. Compared with traditional cutting methods, laser cutting machines are not only inexpensive and low in consumption, but also because laser processing has no mechanical pressure on the workpiece, the effect, accuracy and cutting speed of the cutting products are very good. It also has the characteristics of operational safety, maintainability, simplicity, etc., and can work 24 hours a day. The dust-free cloth non-woven fabric cut by the laser laser machine is automatically sealed without loosening, deformation, or hardening, and the size and accuracy are consistent; it can cut any complex shape with high efficiency and low cost.
Ultrasonic cutting
Ultrasonic cutting has the advantages of smooth and firm incision, accurate cutting, no deformation, no warping, no linting, and no wrinkling. It can avoid the shortcomings of "laser cutting machine" such as rough cutting, burnt edge, and pilling, but at present, ultrasonic cutting machine is more difficult than laser cutting machine in automation, so the efficiency of laser cutting is higher than that of ultrasonic cutting.
