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 workpiece quality. The modern laser has become the "sword" of the "cutting iron and mud" that people are imagining. Laser Equipment Manufacturer to explain to everyone.
Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged by pulse, thereby outputting a controlled repeated high-frequency pulsed laser to form a beam of a certain frequency and a certain pulse width, and the pulsed laser beam is transmitted and reflected through the optical path and focused by the focusing lens group. On the surface of the processed object, a subtle, high-energy-density spot is formed. The focal spot is located near the surface to be processed, and the material to be processed is melted or vaporized at an instant high temperature.
Each high-energy laser pulse instantly sputters a small hole in the surface of the object. Under computer control, the laser processing head and the material to be processed are continuously moved relative to each other according to the pre-drawn pattern, so that the object is processed into the shape you want. When cutting, a coaxial airflow with the beam is ejected by the cutting head, and the molten or vaporized material is blown out from the bottom of the slit (Note: if the blown gas and the material being cut produce a thermal reaction, the reaction will provide cutting The additional energy required; the airflow also cools the cut surface, reduces the heat-affected zone and ensures that the focusing mirror is not contaminated). Compared with traditional sheet metal processing methods, Laser Cutting Machine has high cutting quality (narrow slit width, small heat-affected zone, smooth cut), high cutting speed, high flexibility (can be cut freely), and wide range. Material adaptability and other advantages.
