Laser marking machine at work due to the processing of different thickness of the product, so it is necessary to work with the focus adjustment function, before the old section of the laser marking machine basically did not install an infrared laser marking machine-focus system, so the operation is too much trouble, Now all laser marking machine models are fitted with infrared autofocus system, laser coders its essence is a focal length can be adjusted up or down to adjust the mechanical structure. Current laser marking machine There are two ways to adjust the focal length of the cavity lifting and bench lift two kinds. Resonator lift focus adjustment, due to the weight of the cavity is determined by the design of the machine, not with the laser machining of workpieces of different changes. Also due to the small cross-sectional area of ??the cavity, suitable for Ω-type linear guides and linear bearings, greatly improving the stability of the movement, the whole body parts small, simple mechanical principles. As a result of the lifting of the cavity mode, which is particularly suitable for machines with the use of the line. Jun crown laser company equipment, including: fiber laser marking machine, the semiconductor side pump laser marking machine, CO2 laser marking machine, end-pumped laser marking machine laser marking machine coding machine, metal laser cutting machine, laser welding machines, laser inkjet printer, wire laser engraving machine, laser peeling machine, laser stripping machines, laser coders monitor laser marking machines, and other industrial laser equipment. For more information you can contact in order to make the CO2 laser crown Jun Jun crown excited semiconductor laser equipment and laser marking machine compared to conventional machining, laser marking machines use high energy density of laser irradiation on the workpiece locally, and the material surface vaporization of a chemical reaction or color change, so that the material leaving the processing of a permanent marker. Laser marking is a very fine spot to play a variety of symbols, text, graphics, etc., spot size can microns. Micro machining or security has a deeper meaning. Laser processing non-toxic, non-polluting production processes, machining products to meet environmental standards in Europe and America, is a safe and clean way of processing. Machining mode advanced, high efficiency, after focusing the laser beam as the fine cutting tool, the surface material can be removed by point, its advancement in that the process is non-contact processing, does not produce mechanical compression or mechanical stress, it will not damage to be processed goods; small laser spot because of the focused laser marking machine marking machine, small heat-affected area, working fine, so you can complete some conventional methods can not achieve the process.
