Introduction
This work order recorded a deep engraving test on a brass coin. The test focused on producing a World Cup-related relief effect on a metal coin sample using a GM-100 fiber laser.
1. Test Goal
This test was to verify whether the GM-100 fiber laser marking machine could deep engrave a detailed football-themed relief design on a brass coin. The test needed to confirm whether the machine could produce visible depth and clear surface detail on the brass sample.
2. Test Requirement
The requested sample was a brass coin. The required effect was deep engraving with World Cup-related visual elements, based on the provided reference image.

5. Test Result
The brass coin sample was processed successfully, and the source record marked the result as good. The recorded marking time was 30 minutes. The result image shows a deep relief-style football player design engraved on the brass coin surface with visible dimensional detail.
6. Test Conclusion
The test confirmed that the GM-100 fiber laser could complete deep relief engraving on the brass coin sample and achieve a clear dimensional engraving result. The processed surface showed visible depth and detailed relief features, making this setup suitable as a reference for brass coin engraving and similar metal relief applications.
This type of result is useful for commemorative coins, custom medals, metal craft pieces, logo relief engraving, and small-batch personalized metal products where depth, surface detail, and decorative value are important. Before batch production, the final parameter values should be confirmed with the same material, artwork file, lens setup, and marking software.
