Maintenance of laser engraving machine 1、 Lens cleaning: regularly clean the lens. Generally, the Xiaobian suggests that the cleaning frequency should be once a week. In special cases, the cleaning frequency should be adjusted appropriately according to the working intensity of the equipment. Customers whose processing materials are mainly wood need to strengthen the cleaning times to ensure the processing efficiency and effect of products. 2、 Guide rail care: the guide rail shall be maintained regularly. It is recommended to maintain it at least every 6 months, mainly to apply lubricant (industrial lubricant) to the track. Customers who process cloth, leather, plush and other materials should pay more attention to the maintenance of the guide rail. It is best to clean and maintain it in time after processing on the same day. 3、 Water cooling system (for glass tube machine): regularly replace the cooling water for cooling the laser. Customers using the water pump should pay attention to prevent sundries in the water. Once there are sundries, they will enter the laser tube, which may cause the light output failure of the laser tube. Users using the water cooler should also pay attention to changing the water frequently in summer. It is recommended to replace it every two weeks to ensure the normal operation of the laser machine. 4、 Intermittent use and maintenance (especially for college customers): if you do not use the equipment for a long time, you need to pour out the water in the laser tube and wrap the equipment at the same time.
