What is the principle of laser cutting

Laser cutting is a machining technique that utilizes high-energy laser beams and optical lenses to process workpieces. The principle is to generate a high-energy laser beam through a laser, then focus it into a tiny spot through an optical system, concentrate it on the workpiece for instant heating and melting, thereby achieving the cutting purpose.

The principle of laser cutting is actually not complicated, mainly including the following steps:

Firstly, the working principle of the laser. Laser generates laser through the action of external electrical or optical energy. Laser has the characteristics of high energy, high consistency, and high straightness, making it an ideal processing tool.

Next is the working principle of the laser focusing system. The laser is focused into a very small spot through a lens, concentrating its energy density in a very small area, thereby achieving high-precision machining of the workpiece.

Then there is the interaction between the laser and the workpiece. When the laser beam is focused on the surface of the workpiece, it generates high temperature, high-energy local heat, which instantly melts or vaporizes the surface of the workpiece, forming cutting grooves.

Finally, there is the control of processing speed and movement. During the cutting process at Shenzhen Machinery Processing Factory, the laser beam needs to move along a designed path and control the processing speed and power of the laser beam to ensure precise machining of the workpiece.

In general, the principle of laser cutting is to use the high energy and optical focusing system of the laser to concentrate it on the workpiece, achieving precise machining of the workpiece. Laser cutting technology has the advantages of high processing accuracy, fast speed, and small deformation, and has been widely used in various fields, becoming an indispensable processing technology in modern manufacturing.
