Laser Engraving 3D Relief 5th Anniversary Commemorative Coin

After completing the relief engraving, do not move the material. Create a fill shape the same size as the relief image, set the previously engraved relief image to “Do Not Execute,” and move the fill shape on top of the relief image so that it fully covers it. Set the fill shape to “Execute” and switch it to Deep Engraving mode. After setting the parameters, proceed with processing. The deep engraving step is used to remove the metal surface oxides generated during the relief engraving. Once the deep engraving is complete, allow the material to cool, then use sandpaper to smooth and finely polish the engraved areas of the coin.

The relief engraving process for brass coins follows the same operational steps as the relief engraving process for zinc alloy coins.
