During the working process of the laser welding machine, the laser intensity becomes weaker. Solution: Check whether there is any water seepage on the end face of the laser rod. If there is, stop the machine, re-tighten the sealing O-ring, and clean and maintain the end face of the laser rod. The focusing lens is… Continue reading The laser intensity of the laser welding machine becomes weaker
Laser cutting machine protective lens is used to prevent dust and slag splashes from damaging the focusing lens. It is also necessary in other laser equipment, including laser marking machine, laser welding machine and laser engraving machine, etc.. If the protective lens is not selected properly, it will cause high laser loss, frequent damage to… Continue reading How to Choose the Protective Lens for Laser Cutting Machine?
If we need to mark large-format products but find that the laser marking machine can’t mark so large, how to do? In fact, this time replacing a field lens can solve it. A field lens, also known as a flat-field focusing lens, scanning lens, or F-theta lens, is a necessary accessory for a laser marking machine.… Continue reading How to Expand the Marking Range of Laser Marking Machine?
Due to the working environment, the optical lens of the fiber laser marking machine may be contaminated. Therefore, after a period of use, if not maintained in time, dust will corrode the lens coating. The lens with damaged coating cannot reflect light and cannot pass through the laser. On the contrary, it will absorb the… Continue reading How to Maintain the Lens of Fiber Laser Marking Machine?
There will be some problems in the use of the laser marking machine, such as the laser attenuation, how to deal with? What are the reasons for the laser attenuation of the laser marking machine? 1. The power supply is insufficient. That is, the power supply is damaged. Solution: replace the power supply with a… Continue reading How to deal with the laser attenuation of laser marking machine?
Fault reasons and solutions ①The marking surface is not parallel to the field lens. Adjust the marking surface to make it parallel to the field lens. ②There are stains on the surface of the field lens. Clean the surface of the field lens.. ③The workpiece itself has stains or unevenness. Clean the workpiece or avoid… Continue reading The pattern printed by the laser marking machine is partially unclear
The galvo is not adjusted to the proper position. Vibrating plate, beam expander, lens, etc. need to clean up dust and dirt. The power of laser marking machine is not adjusted to the appropriate value. Whether the power supply current is stable and working normally. The laser needs to be inflated or replaced with a… Continue reading What is the reason for the unclear laser marking ?
Adjust the beam expander position.Tighten the lens and galvanometer.Adjust marking speed.Check if the current is stable.Clean the lens dust.
1. Remove the focus lens from the holder by gently rotating it. 2. Bend the lens wipe paper into a few folds, and then wet it with cleaning fluid. 3. Gently wipe the surface of the lens with the wet lens paper. It needs to repeatedly wipe several times until the lens is clear and… Continue reading How to Clean the Focus Lens of Laser Marking Machine?
