Acrylic laser engraving machine uses infrared light band, 10.64μm gas laser, and fills high pressure discharge tube with CO2 gas to generate glow discharge, so that gas molecules release laser, and the laser energy is amplified to form a laser beam for material processing. The laser beam vaporizes the surface of the object to achieve the purpose of engraving. Acrylic laser engraving machine adopts electric lifting work platform, which is suitable for engraving and processing of objects with different thicknesses. It is convenient and fast, and it is in one step, which greatly improves the work efficiency and processing quality. Optional autofocus system for precise autofocus. Rotary engraving device can also be selected to precisely engrav various cylindrical and circular vertebra objects. https://www.cllaser-technology.c...r-engraving-machine.html
