The laser output power soars up with the latest generation of four 6W laser coupling technology, is able to cut off 12-15mm thick tungsten board as well as the 8mm thick black acrylic board with only one pass, and even cut the 0.05mm thick stainless steel sheet. Upgrade Air Assist Kit: The cutting capacity is greatly improved, as well as the cutting accuracy and quality is optimized to a considerable extent.Upgraded Laser: No need to adjust the focus before engraving. The focusing spot area of the new laser is only 1/3 of other ordinary lasers. Combine precision engraving and high energy cutting at the same time. The laser power of the fixed-focus laser is more stable than the zoom laser. Precise Scale Lines Axis: There are precise scale lines on the X-axis and Y-axis to facilitate quick length measurement. 400x400mm large area engraving interval can meet your various engraving needs. Wide Compatibility: The machine can be compatible with various mature engraving software, such as LaserGRBL, LightBurn, support Win XP/ 7 /8 / XP / 10, and also support MAc system (LightBurn), engraving file format supports NC, BMP, JPG, PNG, DXF etc. More Function: Uses an integrated screw rod which makes the movement of the laser more precise and the coupling more durable. Support offline engraving; In the event of an unexpected situation, stop the machine at any time to make the engraving safer. The laser sintering temperature is up to 2400?
