In summer, the weather is getting hotter and the temperature is rising. In the hot summer, the laser cutting machine should be maintained to prevent heat stroke. Therefore, in order to avoid the failure of the laser cutting machine in summer, we must pay attention to the maintenance and repair of the laser cutting machine, which can extend the service life of the machine.
Maintenance points 1. Water cooling equipment
Water cooler is a necessary cooling equipment for laser cutting machine. In high temperature environment, the coolant deteriorates rapidly. It is recommended to use distilled water and pure water as the coolant. During use, the scale attached to the laser and the pipe shall be cleaned regularly to avoid the blockage of the coolant due to the accumulation of scale, which may affect the cooling of the laser. The temperature of the coolant should not be too different from the room temperature to avoid condensation due to excessive temperature difference. As the temperature gradually increases in summer, the working pressure of the cooling system of the laser cutting machine increases dramatically. It is recommended to check and maintain the internal pressure of the cooler before the high temperature comes, and adjust it to adapt to the high temperature.
Maintenance points 2. Lubrication
All transmission parts need to be wiped and dusted frequently to ensure that the equipment is clean and tidy, so that the equipment can operate more smoothly. The guide rail and gear need to be filled with lubricating oil. The filling interval should be adjusted, which is about twice as short as that in spring and autumn. The oil quality should be observed frequently. For machinery working in high temperature areas, the viscosity grade of oil should be properly improved. The temperature of fat oil is easy to change, so oil should be properly added to ensure lubrication without impurities. Carefully check the straightness of the cutting table and rail of the laser cutting machine and the perpendicularity of the machine, and timely maintain and debug if abnormal.
Maintenance points 3. Circuit inspection
Check and replace the aging wires, plugs, rubber hoses and connectors. Check whether the pins of electrical components and parts are loose, and tighten them in time to avoid electrical burning and unstable signal transmission caused by poor contact. The equipment has a certain loss when it is used, especially when the high temperature summer comes, protect the laser cutting machine and keep it in good condition, so as to bring greater benefits to itself.
Maintenance points 4. Avoid condensation of dew
The temperature of cooling water shall not be too different from that of air. The laser and optical lens of the laser cutting machine are both water-cooled. As the water in the air will condense into water when it is cold, when the temperature of the cooling water is 5-7 degrees lower than the room temperature, there will be dew condensation on the surface of the laser and optical lens, which greatly affects the light output efficiency of the laser and the transmission of the optical lens, and has a great impact on the laser energy and the service life of the optical accessories. It is recommended that the majority of laser cutting machine users set the water temperature at 30-32 degrees, and control the temperature difference between cooling water and room temperature to be greater than 7 degrees.
Maintenance points 5. Guide rail maintenance
The guide rail shall be cleaned regularly to remove dust and other sundries, and ensure that the laser equipment's normal rack is wiped and lubricated regularly to ensure that it is lubricated and free of sundries. Regularly clean and lubricate the machine, so that the machine can be in a better position and cut more accurately, and the quality of the cut products will be improved.
Maintenance points 6. Metal laser cutting machine
As the dust of metal laser cutting machine is mainly metal powder, it is recommended to regularly clean the dust in the gas cabinet of the laser cutting machine and check the working condition of the cooling fan.
summary
The climatic characteristics of each season vary greatly. Laser cutting machines are expensive processing and equipment with high precision requirements. Scientific and orderly maintenance based on climatic characteristics can effectively avoid minor problems in the laser cutting process and improve the service life of laser cutting machines.
