Laser marking machine adjustable mirror beam expander. Laser marking machine beam expander mirror adjustments required: First, to ensure the incident beam expander to be in the center of the laser light into the hole peeling machine coders, outgoing light in the center of the hole to be light; beam expander to adjust the quality of the laser marked effects have a significant impact. Mainly in: a laser power down; b internal format uneven marking laser intensity; c computer software design center deviate galvo the photophysical center .... d. not play a beam expander effect. On the beam expander tube also has six adjustable screws. If the beam expander offset large, can not fine-tune the calibration, proceed as follows: first, by adjusting the three adjustment screws from the back of the laser beam expander tube front center of the light emitted from the hole; the second step of laser stripping machine wholesalers, by adjusting the three adjustment screws so that the front of the reflected light with red concentric red. When the adjustment to meet the requirements, you can clearly see by the large number of concentric rings return spot shines on the red laser white grating, and concentric. Because of its weak flare, during the second part is recommended in low-light environments. The third step is the first step in the process is repeated. If the beam expander offset much, but also to ensure that the case of the red light collimating coaxial laser and red light, you can observe the red light is roughly from the center beam expander to enter, it is also the center of the laser beam expander peeling machine Coding machine, the marking software inside the box draw close to full format, continuous high-speed, beat in the flat metal surface, under normal circumstances should the energy evenly on all sides, if uneven trimming beam expander, remember a few laps rotation, if fine-tuning After the energy difference between the sides need more adjustment in the opposite direction, and ultimately achieve each side evenly. CO2 laser marking machine for non-metal industry, fiber and semiconductor laser marking machine for metal industry and some non-metallic industries, CO2 can be sure it is a marking on the glass. CO2 laser marking machine has three methods can be used to crack type and amount of the generated control glass surface: The first method is to use multiple laser radiation; second method is the use of discrete points to form a cyclic crack; third method is crack-like surface cracks. Using a laser radiation to produce a visible mark with a clear edge on the glass, but the direction of the crack and stress patterns will move perpendicular to the direction of extension of the laser. After a few days or even a short time, these vertical cracks in the movement direction of the laser will be formed after the mark to print a new crack, extending to the vicinity of the original mark outside fragmented laser peeling machine, thus affecting the clarity of labeling. The use of multiple laser radiation, so that the marking area adjacent to the area to be heated by heat conduction, so that the stress gradient formed in these regions, reducing the possibility of secondary breakdown. In this marking method on a soda lime glass and borosilicate glass is very effective. A laser radiation in the melt into a marking on the silica glass and quartz glass is more effective, because these two materials is very low coefficient of expansion. Laser marking machine marking process is in contact with the glass laser, so there is no mechanical force and cutting force generated in this process, marking not destroy beautiful glass appearance.
