YAG laser cutting machine cutting technology introduction

YAG laser cutting machine is a kind of commonly used laser cutting machine. This kind of laser cutting machine is widely used in metal material processing, mainly for the cutting of thin metal sheets. So what about the cutting technology of YAG laser cutting machine? Let's understand together a bit.　　YAG laser cutting machine has many advantages, which not only greatly reduces the processing time, but also reduces the processing cost and improves the quality of the workpiece. Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged through pulses, thereby outputting a controlled repetitive high-frequency pulsed laser to form a beam with a certain frequency and a certain pulse width. The pulsed laser beam is guided and reflected by the optical path and focused by the focusing lens group. On the surface of the processed object, a small, high-energy-density light spot is formed. The focal spot is located near the surface to be processed, and the processed material is melted or vaporized at an instant high temperature. Each high-energy laser pulse instantly sputters a small hole on the surface of the object. Under computer control, the laser processing head and the processed material perform continuous relative movement according to the pre-drawn graphics, so that the object will be processed into The shape you want. When cutting, a stream of air coaxial with the beam is ejected from the cutting head to blow the melted or vaporized material from the bottom of the incision. The additional energy required; the airflow also cools the cut surface, reduces the heat-affected zone and ensures that the focusing lens is not polluted). Compared with traditional plate processing methods, laser cutting has high cutting quality (narrow cut width, small heat-affected zone, smooth cut), high cutting speed, high flexibility (can cut any shape at will), and a wide range of materials Adaptability and other advantages.　　 Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete equipment.
