What is the difference between laser cutting and ultrasonic cutting?
principle(1) 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. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby achieving the desired cutting effect on the workpiece. cutting.
(2)Principle of ultrasonic cutting
The principle of ultrasonic cutting is to transmit the ultrasonic energy generated by the ultrasonic transducer to the horn, and then the horn amplifies the ratio and then transmits it to the cutting knife to drive the cutting knife to vibrate at high frequency. Under the action of huge ultrasonic energy, the cutting The position instantly softens and melts, and the strength is greatly reduced. Only a small amount of force is required to cut the material.
Advantage(1) Laser cutting characteristics
As a new processing method, laser processing has been widely used in the leather, textile and clothing industries due to 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 cheap and low in consumption, but also because laser processing does not put mechanical pressure on the workpiece, the effect, accuracy and cutting speed of the cutting product are very good. It also has operational safety and maintainability . Simple and so on. Can work 24 hours a day. The lint-free non-woven fabrics cut by laser machines are automatically edge-sealed and do not loosen, deform, or harden, and have consistent size and accuracy; they can cut any complex shape; they are highly efficient and low-cost.
(2) Characteristics of ultrasonic cutting #
Ultrasonic cutting has the advantages of smooth and firm incision, accurate cutting, no deformation, no warping, no lint, no wrinkles, etc. It can avoid the shortcomings of "laser cutting machines" such as rough cutting, burnt edges, and pilling. However, ultrasonic cutting machines are currently more difficult to automate than laser cutting machines, so laser cutting efficiency is currently higher than ultrasonic cutting.
