Features: Solid And Easy Installation Structure Design: All-aluminum alloy anodized structure design makes the machine more durable, and improves the accuracy of engraving. The entire machine structure can generally be completed within 10-20 minutes. New Filter Eye Protection Acrylic Design: The filter acrylic protective cover plays a good role in protecting your eyes, filtering 97% of ultraviolet light, free to watch the laser engraving without goggles. Upgraded High-Performance Fixed-Focus Laser: No need to adjust the focus before engraving and more stable than the zoom laser as well; The new laser focal spot is 50% smaller than other ordinary lasers, new laser 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. Newly Upgraded Ultra-Fine Compressio n Laser:  Adopts 4-fold lens group collimation and focus technology, the optical power is 5-5.5W, laser focus area is reduced to 0.08*0.08mm. The high-density laser can easily cut 15mm thick wooden boards, 15mm black acrylic; Directly engrave mirror stainless steel metal and ceramics, and can achieve the effect of a 100W CO& 8322; laser engraving machine.  Precise Scale Lines Axis : There are precise scale lines on the X-axis and Y-axis to facilitate quick length measurement. 410x400mm 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 / Win 7 / Win 8 / XP / Win 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. In the event of an unexpected situation, stop the machine at any time to make the engraving safer. Even without terminal, A5 M50 still can offline engraving by connecting WiFi and transfer the data to TF card to realize.
