People often assume that removing laser engraving requires nothing more than polishing the metal to provide a clear surface for a new engraving. What they do not stop to consider is the material used for the initial engraving and the depth of the marks. Both play a crucial role in the success or failure of this attempt. To remove an engraving, a jeweler has to laser the metal in the engraving area, flying it to level the texture of the metal.
Once this is done, the jeweller polishes the item and returns it to a smooth, blank surface. While there are situations where a person may want laser engraving marks removed, there are also situations where removing marks can be disastrous. I bought a stainless steel watch from a pawnshop after looking at it, the name of the previous owner is engraved on it, can I remove it? Thank you for your time. Although the process of removing the engraving requires little skill to learn, it takes a long time to remove the engraving.
For example, laser engraving a sign for a hospital may not be appropriate if the material used cannot withstand the aggressive cleaning substances required in this environment. The pneumatic sander sends a stream of air instead of rubbing or moving across the surface, reducing control over what is removed from the metal part in question. If necessary, try these steps on an inconspicuous area of the object before removing engravings everywhere so you can see if they work well enough for your needs. This is an important step because the cleaner the metal is, the easier it will be to remove the engraving.
Usually, most engravings are made by laser engraving, which engraves the engraving on the surface of the metal. Cheap costume jewellery metals containing zinc, lead or pewter do not react well to laser or polishing, and may even disintegrate in the process. This is because gold and silver plated jewelry varies from high quality material to low quality material under plating, and the process of removing the engraving will remove the plating. The upper surface of the item to be engraved must be smooth, as the laser engraving process melts this layer to produce the desired marks and the engraving will not be legible if the surface is roughened in any way.
Removing marks from this type of material in the hope of re-engraving it will not be beneficial. Feel free to talk to a laser engraving supplier to learn more about the materials to be selected and the process that should be used to ensure that the finished project is the desired one.
