What is the principle of laser cutting technology

Laser cutting technology relies on high-energy density laser beams that can quickly heat materials to their melting or vaporization points, creating a cut on the material. The width of the incision is usually very small, around 0.1 millimeters, depending on the power and focus of the laser beam used. As the laser beam moves along a predetermined path, a series of cuts appear continuously on the material, ultimately forming the desired shape of the cut.

During the laser cutting process, in addition to the laser beam itself, a high-speed airflow, usually compressed air or inert gas, is required to blow away the melted or evaporated material, preventing it from re solidifying or contaminating the cutting edge. This method not only improves the accuracy of cutting, but also reduces the heat affected area of the material, ensuring the smoothness of the cutting edge.

As a thermal cutting technology, laser cutting can achieve cutting without contacting the material, avoiding the wear and deformation that may be caused by mechanical shearing or other physical contact methods. In addition, laser cutting is suitable for a variety of materials, including metals, plastics, glass, and ceramics, and can cut various materials with thicknesses ranging from a few micrometers to a few centimeters.

With the advancement of technology, the cost of laser cutting equipment is gradually decreasing, making its application in manufacturing increasingly widespread. The advantages of laser cutting lie in its high precision, fast speed, and good cutting quality, making it particularly suitable for cutting tasks with complex shapes and high-precision requirements.
