Mini Fiber Laser Marking Machine for Metal Engraving

CrossWay Yi Standing Model 20W Full watts fiber laser Marking Machine can achieve a deep marking depth of up to 1–2 mm, although the exact depth depends on the material type, its thickness, and laser settings like speed and power. For deep engraving, multiple passes are necessary, and it's often required to clean the material between passes to remove oxidation, which can hinder laser penetration. Some manufacturers list the marking depth as ≤1 mm or even up to 3 mm in their specifications. https
