Laser cutting technology is widely used in the processing of metal and non-metal materials, which can greatly reduce processing time, reduce processing costs and improve the quality of the workpiece. Modern laser has become the "sword" of "cutting iron like mud" that people fantasize about pursuing. Laser cutting is realized by using high power density energy produced by laser focusing. Under the control of computer, the laser is discharged by pulse, and the controlled repetitive high frequency pulsed laser is output to form a beam with a certain frequency and a certain pulse width. The pulsed laser beam is transmitted and reflected through the optical path and focused on the surface of the processed object through the focusing lens group, forming a fine, high-energy beam. Quantitative density spot. Focus spot is located near the surface to be processed. It melts or gasifies the processed material at high temperature instantaneously. Every high-energy laser pulse instantaneously splashes a small hole on the surface of the object. Under the control of computer, the laser processing head and the processed material move continuously and relative to each other according to the pre-drawn figure, so that the object can be processed into the desired shape. When cutting, a coaxial flow of gas and light beam is ejected from the cutting head, and the melted or gasified material is blown out from the bottom of the cut. The effect of contamination. Compared with traditional plate processing methods, laser cutting has many advantages, such as high cutting quality (narrow cut width, small heat affected zone, smooth cut), high cutting speed, high flexibility (arbitrary shape can be cut at will), wide material adaptability and so on.
