1. The lens has stains or scratchesSolution: If there are stains, you can use a cotton swab and alcohol to wipe the lens, beam expander, and focusing lens, wiping off the surface material. Remember not to use hard objects to wipe the lens; If there are scratches or other damages on the lenses, the only option is to replace the marking machine lens....

The principle of a laser marking machine is to vaporize the surface of a material in an instant through the high temperature generated by laser focusing, and generally the color of the material itself is printed out.The color of metal laser marking mainly depends on the nature of the material, followed by the size of the laser force (i.e. power, ...

The causes of cracksDuring the fusion process, the high-energy laser beam rapidly heats up, causing a significant temperature gradient between the fusion layer and the substrate. In the subsequent cooling, the volume of the cladding layer and the substrate is inconsistent, which constrains each other and generates stress.During the growth process ...

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...

1. More environmentally friendly: No need to use any chemical agents or cleaning liquids, the cleaned waste is basically solid powder, small in size, easy to store, recyclable, non photochemical reaction, and does not produce pollution.2. Good effect: Laser cleaning is non abrasive, non-contact, and has no thermal effect. It does not generate mec...

Sometimes 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...

Defects in copper alloy laser welding1. Welding stressThe coefficient of linear expansion and shrinkage of copper are also relatively large. The coefficient of linear expansion of copper is 15% higher than that of iron, and the shrinkage rate is more than twice that of iron. In addition, copper and copper alloys have strong thermal conductivity, wh...
