Metal accounts for a large proportion of the phone keypad laser engraving machine marking material, such as anodized aluminum, stainless steel, copper and titanium. Aluminum, brass and copper such as a highly reflective material marking car keys laser engraving machine, require a high pulse peak power and a sufficiently high power density laser marking speed peak energies can reach 500mm / s . Dark anodized aluminum surface oxide film, the film to a higher absorption of infrared radiation elevator button laser engraving machine, so in fact require a lower power density, marking speed up to 2m / s. To achieve the above-described marking speed, require a high pulse repetition frequency, because if the speed is too fast and the pulse overlap is not enough, can lead to rough and not coherent line identification; higher pulse frequency pulse overlapping degree can be increased, so that a uniform line identification smooth. Fiber laser operating frequency exceeding 100kHz, which is also applied to the marking field advantage. Annealing the type marking button laser engraving machine on the stainless steel material, the resulting identity is clear, black identity and no material is removed during processing. Now this marking process has been widely used on the stainless steel products 1. Check all power cable; 2. high pressure krypton lamp aging, replacement krypton lamp. Operation Laser Marking Machine Note 1. Start the laser power and non-power Q-water or water circulation under unusual circumstances; 2. Q power load is not allowed to work (ie, Q-power output vacant); 3. abnormal phenomenon , first turn off the galvanometer switch and key switch, re-examination; 4. not allowed to start before the krypton lamp lit other components to prevent damage to the components fleeing high pressure; 5. Note that the laser power output (anode) vacant, to prevent and other electrical ignition, breakdown; ⑥ clean and maintained in the circulating water. Regularly clean the tank and change a clean deionized water or pure water.
