Laser marking technology is an important part of laser processing. It is currently a widely used and mature technology in the field of laser processing.
First of all, for a fixed marking pattern, the factors that affect marking efficiency can be divided into the equipment itself and the processing material. Therefore, it can be concluded that the filling type, field lens, galvanometer, delay and other factors that affect the marking efficiency.
During the use of the laser marking machine, its built-in settings are the main internal factors. Among them, the laser frequency, laser spot mode and beam divergence angle, laser power, reasonable optical shaping and auxiliary gases and substances during processing are all Has a certain impact. Therefore, when selecting the laser marking machine model in the early stage, the material and process requirements of the product should be followed to select.
In the case of the same format, the same spot, and the same depth, the higher the marking density, the slower the corresponding marking speed. The reason is that the density directly increases the marking area.
Under normal circumstances, the scanning speed of the galvanometer can reach 3000mm/s, but a better high-speed galvanometer can scan tens of thousands of times per second. In addition, when using ordinary galvanometers to mark small graphics or fonts, deformation is prone to occur, and it is necessary to reduce the scanning speed to ensure the effect.
the larger the format of the mark, the greater the deflection angle of the laser marking galvanometer and the graphic movement track. Therefore, under the same marking speed, the marking speed of large format takes longer than the marking speed of small format.
The application of laser marking machine requires technical personnel with certain application experience to participate in the operation to better complete the good marking effect. At the same time, the fiber laser marking machine also needs to know the daily maintenance and cleaning, and understand the basic structure and structure. In order to improve the use effect of fiber laser marking machine.
