Principle:

 

(1) Laser cutting principle:

The principle of laser cutting Laser cutting is to use a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and at the same time blows out the molten material by means of a high-speed airflow coaxial with the beam, thereby Achieve the cutting of the workpiece. Laser cutting is one of the thermal cutting methods.

 

(2) Principle of ultrasonic cutting:

When using ultrasonic technology for cutting processing, the forward and backward vibrations generated by the ultrasonic vibrator installed behind the main shaft are transmitted to the outer part of the grinding wheel blade through the abutment of the main shaft and the grinding wheel blade, and converted into a radial expansion motion. With this vibration conversion method, the ideal vibration direction required for ultrasonic processing can be obtained.



Characteristics:


(1) Laser cutting characteristics:

Laser processing, as a brand new processing method, has gradually been widely used in the leather, textile and clothing industries due to its advantages such as accurate, fast, simple operation and high degree of automation. Compared with the traditional cutting method, the laser laser cutting machine is not only low in price and low in consumption. Also, because laser processing does not have mechanical pressure on the workpiece, the effect, accuracy and cutting speed of the cut product are very good. It also has operational safety and maintenance Simple and other characteristics. Can work 24 hours continuously. The non-woven cloth and non-woven cloth cut by laser laser machine have no yellowing edge, automatic closing without loosening, no deformation, no hardening, consistent and accurate size, can cut any complex shape, high efficiency and low cost, Computer designed graphics, can cut any shape of any size lace. Fast development speed: Due to the combination of laser and computer technology, as long as the user designs on the computer, the laser engraving output can be realized and the engraving can be changed at any time. The product can be designed while designing.


(2) Characteristics of ultrasonic cutting:

Ultrasonic cutting has the advantages of smooth and reliable incision, accurate cutting edge, no deformation, no warping, fluffing, drawing, wrinkling, etc. The avoidable "laser cutting machine" has the shortcomings of rough cutting edges, defocusing edges, and pilling, but the ultrasonic cutting machine is currently more difficult than the laser cutting machine in automation, so the current laser cutting efficiency is higher than the ultrasonic cutting.
