With the rapid development of science and technology, 3D laser engraving machines are becoming more and more popular due to their advantages such as wide processing range, high precision, long service life and environmental protection. The following editor will give you some maintenance suggestions for 3D laser engraving machines. There are four points for attention in the maintenance of 3D laser engraving machine: First, keep the room and the surface of the machine clean and tidy, regularly check each optical lens for dirt (the term depends on the working environment), and if there is dirt, scrub it in an emergency. How to Scrub: Be very careful when cleaning the lens. Before cleaning the lens, it is strictly forbidden to replace the protection circuit and main parts of the laser at will. Three-dimensional laser engraving machine Secondly, it is strictly forbidden to start the laser power supply and Q-switching power supply when there is no water or the water cycle is abnormal, and the Q-switching power supply is not allowed to work without load (that is, the output of the Q-switching power supply is suspended). First turn off the galvanometer switch and key switch, then check and pay attention to the suspension of the laser power output (anode) to prevent ignition and breakdown with other electrical appliances; in addition, keep the internal circulating water clean. Regularly clean the water tank of the laser engraving machine and replace it with deionized water or pure water. It is not allowed to start other components before the krypton lamp is lit to prevent high voltage from invading and damaging components. Afterwards, configure the laser water cooler to effectively cool the marking machine module and Q head, and prevent the marking machine from overheating. In the process of use, the above items should be observed and the laser equipment should be used correctly to prolong the service life of the equipment and reduce the cost.
