How to solve the problem of unclear ghosting in laser marking machine engraving

The occurrence of ghosting or blurriness during engraving operations on laser marking machines may be due to various reasons. To solve this problem, it is usually necessary to follow the following steps to check and adjust:

1. Check the optical system:
Confirm whether the laser and its optical components (such as lenses) are clean, as dust and stains can cause the laser to diverge and affect the quality of marking. Check if the light path is aligned. If the beam is not very concentrated or the light path system is offset, it can cause blurring or ghosting.

2. Adjust the focal length:
Calibrate the focal plane of the laser head to ensure that the focal point during laser marking is in the appropriate position on the surface of the marking material.
The height of the laser head can be adjusted appropriately or the focal length parameter can be adjusted through software.

3. Focus check:
Use a focusing tool or manually adjust the focus to a clear state. The focus point is only clear when it is in the appropriate position, and the marking will be more accurate.

4. Adjust the marking parameters:
Adjust parameters such as marking speed, power, frequency, etc. Too fast speed or too low power may result in poor marking quality.
Different parameter settings need to be adjusted for different materials and marking depths.

5. Check the positioning of the workpiece:
Ensure that the workpiece is securely fixed during the marking process, as any slight movement may cause ghosting or blurring.
Use appropriate workpiece fixtures to prevent the workpiece from moving during the machining process.

6. Software settings:
Check the settings of the marking software to confirm that there are no incorrect parameter configurations, such as marking times, marking methods, etc.

7. Hardware problem check:
If the above operations still fail to solve the problem, there may be a laser or other hardware malfunction. In this case, the equipment supplier or professional technical personnel should be contacted for inspection and repair.

8. Environmental considerations:
Ensure the stability of the marking environment, as high or low temperature and humidity may affect the marking effect.
By investigating the above issues one by one and adjusting or repairing them according to specific situations, it is usually possible to solve the problem of ghosting or unclear engraving in laser marking machines. If self inspection fails to solve the problem, it is recommended to contact the manufacturer's technical support for further diagnosis and resolution.
