Laser processing refers to the use of the thermal effect of the laser pointer beam projected on the surface of the material to complete the processing process, including laser welding, laser cutting, surface modification, laser marking, laser drilling and micro processing. The laser beam is used to perform various processing on the material, such as drilling, cutting, scribing, welding, heat treatment, etc.
Laser can adapt to the processing and manufacturing of any material, especially in the processing and manufacturing of special materials with special precision and requirements, special occasions and special materials. %20 The principle of laser processing. Laser processing is to irradiate the laser beam to the surface of the workpiece, and use the high energy of the laser to cut and melt the material and change the surface properties of the object.
Since laser processing is a non-contact processing, the tool will not directly rub against the surface of the workpiece to generate resistance, so the laser processing speed is extremely fast, the range of the processed object is less affected by heat, and no noise is generated. Since the energy of the laser beam and the moving speed of the beam can be adjusted, laser processing can be applied to different levels and ranges.
Features of laser processing. The valuable characteristics of laser determine the advantages of laser in the processing field: because it is non-contact processing, and the energy and moving speed of the high-energy laser beam are adjustable, it can achieve a variety of processing purposes. It can process a variety of metals and non-metals, especially materials with high hardness, high brittleness, and high melting point.
There is no “tool” wear during green laser pointer processing, and no “cutting force” acts on the workpiece. In the laser processing process, the laser beam has high energy density, fast processing speed, and local processing, which has no or minimal impact on non-laser-irradiated parts. Therefore, the heat-affected zone is small, the thermal deformation of the workpiece is small, and the subsequent processing volume is small.
It can process various kinds of workpieces in a closed container through a transparent medium. Because the laser beam is easy to be guided and gathered to realize the transformation of various directions, it is very easy to cooperate with the numerical control system to process complex workpieces, so it is an extremely flexible processing method. Using laser processing, high production efficiency, reliable quality and good economic benefits
