Analysis of alarm reasons
Cutting head overheating: When the laser cutting machine operates continuously for a long time, the cutting head may alarm due to overheating. At this time, it is necessary to stop the machine in a timely manner to check the heat dissipation of the cutting head and ensure the normal operation of the heat dissipation system.
Lens contamination or damage: As the core component of a laser cutting machine, if the lens is contaminated or damaged, it can lead to a decrease in the quality of the laser beam and trigger a cutting head alarm. Regular inspection and cleaning of lenses, timely replacement of damaged lenses, is an effective method to avoid such alarms.
Improper adjustment of the focal length of the focusing lens: The adjustment of the focal length of the focusing lens is crucial to the cutting effect. If the focal length is not adjusted properly, it can cause the laser beam to be unable to focus accurately, thereby triggering a cutting head alarm. Therefore, when using a laser cutting machine, it is important to ensure accurate adjustment of the focal length of the focusing lens.
Cutting gas problem: The selection, pressure, and flow rate of cutting gas have a significant impact on the cutting effect. If the cutting gas does not meet the requirements or the parameters are set improperly, it may cause the cutting head to alarm. Therefore, when using a laser cutting machine, it is important to ensure the quality of the cutting gas and correct parameter settings.
Solution
Check the heat dissipation system: When the cutting head alarms due to overheating, the first step is to check whether the heat dissipation system is operating properly. Clean the dust on the heat sink to ensure the normal operation of the fan and improve heat dissipation efficiency.
Cleaning and replacing lenses: Regularly clean the surface of the lenses to remove stains and dust, and keep the lenses clean. If the lens is damaged, it should be replaced with a new lens in a timely manner to ensure the quality of the laser beam.
Adjust the focal length of the focusing lens: Depending on the cutting material, adjust the focal length of the focusing lens to the optimal position. You can observe the cutting effect by cutting different thicknesses of boards and gradually adjust the focal length to the optimal state.
Optimize cutting gas parameters: Select appropriate cutting gas and parameter settings based on the requirements of the cutting material. By adjusting parameters such as gas pressure and flow rate, the cutting effect can be optimized to reduce the possibility of cutting head alarms.
The laser cutting machine cutting head alarm is a problem that needs to be taken seriously. By analyzing the causes of alarms and taking corresponding solutions, we can effectively avoid such problems and ensure the normal operation and production efficiency of the laser cutting machine. At the same time, regular maintenance and upkeep of equipment is also a key measure to reduce alarm rates and extend the service life of equipment.
