Fiber laser engraving machine uses a non-contact processing, the energy released when the laser beam is irradiated to the surface of the work piece to melt and evaporate the work piece to achieve the purpose of engraving. This type of engraving method has the characteristics of high accuracy, fast cutting, not limited to the limitation of cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. Especially when processing carbon steel, stainless steel, galvanized sheet and other metal materials. This fiber laser engraving machine has a wide range of applications such as the sheet metal processing, aviation, electronics, electrical appliances and other industries.
