Fiber Laser Cutting Machines
Glass Laser Cutting Machine
The Glass Laser Cutting Machine uses a Wuhan Huaray picosecond laser source at 30w, 50w or 70w to cut glass on a 500 x 400 mm marble work table.

Fiber Laser Marking Effect Is More and More Light
Published 2019-07-01 by the Weihua Laser engineering desk.
Diagnose Optical Path Deviation First
A faint mark often starts with a misaligned beam. Check the laser light path of the fiber laser marking machine to ensure it is not deviating. Adjust the focal distance to the correct position so the beam hits the material in its best state. If the focus is wrong, the energy density drops and the mark looks weak.
Clean The Lens And Mirrors Properly
Dust and residue on optics absorb energy before it reaches the part. Use a cotton swab with industrial alcohol to clean every mirror and lens in the path. Let them dry completely before marking again. This simple step often restores contrast without changing any software settings.
Verify Power And Speed Settings In Ezcad
Check the data setting in the Ezcad software, specifically the percent of laser power. If the speed is set too high, the mark will be light. Adjust the marking speed and the filling way to a reasonable value. Test different line spaces, usually between 0.08 and 0.15 mm in Ezcad, to find the right density for your material.
Assess The Fiber Laser Source Condition
If the first three steps do not solve the issue, the fiber laser source itself may be weakening. The theoretical service time of a fiber laser source is 100000 hours. If the machine has run for a long time, the output power may have degraded. Consider replacing the source if all other adjustments fail to restore the mark quality.

Buyer Questions
Questions On This Topic
Why is my fiber laser mark too light?
Common causes include a deviated laser light path, incorrect focal distance, dirty lenses or mirrors, low power settings in Ezcad, excessive marking speed, or a weakened fiber laser source.
How do I clean the optics?
Use a cotton swab with industrial alcohol to clean every mirror and lens in the laser path. Allow them to dry fully before running a test mark.
What line space should I use in Ezcad?
A typical range for line space in Ezcad software is 0.08 to 0.15 mm. Adjust within this range to achieve the desired mark density.
How long does the fiber laser source last?
The theoretical service time of a fiber laser source is 100000 hours. If the machine has been running for a long time, the source may need replacement.
What if adjusting settings does not help?
If cleaning optics and adjusting Ezcad settings do not solve the problem, the laser source itself may be weakening. Contact support with your machine details for further diagnosis.
