NEJE Master / Master 2 20W Laser Module Laser Engraving Machine Replacement Head Part CNC Wood Cutting Laser Module Tube

Main applications

Main applications: Cutting, metal engraving, drawing depth engraving, etc. (Especially good at cutting, It can cut wood (3-7mm). It supports metal engraving including alumina oxide, iron oxide and other non-reflective materials With strong power, the engraving depth can reach 1.5-3mm in the engraving mode, and it can cut for a long time in continuous 100% power mode, which is suitable for cutting wooden blocks with a thickness of 3-5mm ( max 8mm ). The NEJE team continuously optimizes the optical system to make the optical power loss less than 1%, the focus point is clear, and the maximum cutting thickness can reach 8mm with the correct focus adjustment. Supported engraving materials: Wood, gray paper, leather, bamboo, blackening plastics, rubber, alumina oxide, iron oxide, etc. Supported cutting material: Wood/ plywood/ leather/ paper. It is not possible to directly engrave the metal with strong mirror reflectivity, which may cause injury to the operator or burn the laser. ) Note: 1. can not engrave on stainless steel, alumina, Alloy, silver and other reflective metal.
