Principle of laser marking
The laser has high brightness, high accuracy, high monochromaticity and high coherence, which is unmatched by ordinary illumination sources. When the laser beam is focused, it can produce thousands of degrees or even tens of thousands of degrees of high temperature at the focus, making it possible to process almost all materials.
Laser marking is the use of a laser beam to inscribe permanent markings on the surface of various materials. The effect of marking is to expose the deep material by evaporation of the surface material, or to "etch" the trace by the chemical and physical changes of the surface material caused by the action of light energy, showing the pattern and text of the desired etching.
Laser marking features
a) It can process a variety of metal and non-metal materials, especially for marking high hardness, high melting point and brittle materials.
b) It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality.
c) The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small.
d) High processing efficiency, computer controlled, easy to automate.
Fiber laser marking machine is a high-tech product integrating laser, computer, automatic control and precision mechanical technology.
The marking machine adopts high-performance digital galvanometer scanning system, which is fast, high precision and can work for a long time. It can be used in most metal materials and some non-metallic materials such as silicon, rubber, epoxy, ceramics, marble, etc. to write or make permanent anti-counterfeit marks that are difficult to copy.
Fiber laser marking machine has good laser optical mode (M2 < 2), small size, stable and reliable operation, no maintenance, no water cooling system, high electro-optical conversion efficiency, low energy consumption; good marking quality; laser power and frequency computer control Easy to implement tag automation.
The company provides dedicated marking software based on the Windows platform. Real-time control of laser power and pulse frequency. The marked content can be text, graphics, pictures, serial number, barcode and their combination, and can be directly input and edited in the special marking software, or edited by graphic software such as AutoCAD or CorelDraw, and the input and output can be controlled by the computer.
The fiber laser marking machine is designed to meet international safety and operational standards.
