Firstly, the focus position of the fiber laser cutting machine affects the cutting accuracy, especially the diameter of the focal spot. The diameter of the focal spot should be as small as possible to produce a narrow slit; The diameter of the focal spot is directly proportional to the depth of focus of the focusing lens. The smaller the depth of f...

2024-03-2155911Sometimes when using a laser marking machine to print something, it may not be obvious. What is the reason for this? In fact, there are many reasons why the laser marking machine may not produce obvious results during use, such as the power of the laser, the focal length, and the material used. We can first check the focal length of the laser marki...
2024-03-1945910During the operation process, selecting different parameters and materials for marking workpieces can affect the marking depth of the laser marking machine, sometimes leading to shallow or deep marking effects. In fact, the marking depth of the laser marking machine can be adjusted to a certain extent. Here are five methods to adjust the marking de...
2024-03-18475101、 High power can improve performance and throughputHigh power laser cutting technology is increasing year by year. In 2015, 4kW laser cutting machines were frequently seen in the North American market. Entering mid-2019, the trend is towards high-power lasers of 6kW and higher. These high-power laser machines not only improve performance and yield...
