Infrared laser engraving machines play an important role in industrial manufacturing and fine processing due to their unique advantages. This blog will introduce in detail the basic principles, key components, technical parameters and performance indicators, advantages, application fields and how to choose infrared laser engraving machines.
Basic Principle
The working principle of infrared laser engraving machine is based on the interaction between laser and material. When the infrared laser beam is irradiated to the surface of the material, due to its high energy density, the material will quickly expand or melt due to heat, thereby achieving the purpose of engraving or marking on the surface of the material. The wavelength of infrared laser is usually 1064 nanómetros, which is suitable for processing materials such as metals and some plastics.
Key Components
Laser
The core of the infrared laser engraving machine is the laser, which is responsible for generating a high-intensity laser beam. The stability and reliability of the laser are crucial to the long-term operation of the machine. Generalmente, a carbon dioxide laser is used, and its power is adjusted according to the different processing methods.
Optical path system
The optical path system is the connection point between the laser and the processing machine, including the linear transmission, refraction, reflection, focusing and dispersion system of the light beam. The infrared laser engraving machine uses the air transmission channel, which is reflected by the reflective part and then focused by the lens, and finally reaches the surface of the processed object.
Computer control system
The control system is the brain of the laser engraving machine, responsible for reading the processing data and controlling the coordination between the various components of the engraving machine. It can convert the image in the computer into a set of scale points that can be recognized by the laser engraving machine, and realize precise control of the workpiece surface.
Mechanical system
The mechanical system includes the laser head, workbench, etc., which are responsible for the movement of the laser head and the fixation of the material. It also includes motion components such as motors, synchronous belts, guide rails, etc.. The accuracy of these components directly affects the accuracy of processing.
