What is the Laser Engraver Air Assist System?
The laser engraver air assist system is an auxiliary device used in the laser engraving and cutting process. It uses an air jet to help control the byproducts generated during the processing, such as smoke, slag and heat. This system is essential to improve processing quality, protect optical components and ensure operational safety.
The Role of the Air Assist System
Improve processing quality
The air assist system improves the quality of cutting and engraving by removing slag and smoke from the processing area and reducing contamination on the material surface.
Protect optical components
The airflow forms a positive pressure around the optical components to prevent dust and debris from contaminating the optical surface and extend the service life of the optical components.
Ensure safe operation
For flammable materials, the air assist system can reduce the risk of fire and inhibit the combustion reaction by reducing the oxygen concentration.
Reduce maintenance requirements
By maintaining a clean working environment, reducing contamination of optical surfaces and moving components, and reducing maintenance costs.
Working Principle
The working principle of the air assist system of the laser engraver is to spray a gas flow at the laser processing point. This gas flow can be air, nitrogen, hydrogen or oxygen, etc. The functions of the gas flow include:
Mechanical removal of by-products
The air flow helps to remove by-products accumulated on the surface and around the material, making the laser cutting and marking products cleaner and more consistent.
Heat conduction
The air flow helps to eliminate the heat generated by the laser processing, which is particularly important for high-temperature sensitive materials.
Chemical environment control
The gas sprayed at the processing point can replace the surrounding air, control the chemical interactions during the laser processing process, and reduce processing defects.
Scope of Application
The air-assisted system is suitable for laser processing of various materials, including but not limited to:
Carbon steel plate/Q235 plate
When air is used as the auxiliary gas for cutting, if the plate thickness exceeds 1.5mm, certain burrs will be generated on the cutting section.
Stainless steel plate/SUS304 plate
When nitrogen is used as the auxiliary gas, the section presents a silvery luster, while when air is used as the auxiliary gas, the section presents a light yellow luster.
Maintenance and Care
To ensure the best performance of the air-assisted system, regular maintenance and care are required:
Clean the optical components
Regularly use lens paper or cotton wool plus medical alcohol to gently wipe the optical lenses to keep them clean.
Check the airflow
Make sure the airflow is stable and unobstructed to ensure the processing effect.
Check the air source
Select an air source suitable for laser processing, considering the air cleanliness, oil content and water content.
Impact on the Environment
Reduce carbon emissions
By using air as an auxiliary gas, the dependence on gases such as nitrogen or oxygen can be reduced, thereby reducing carbon emissions in the process of gas purification, pressurized liquefaction, storage, and transportation.
Improve the recycling of resource utilization
Using air as an auxiliary gas can be directly obtained from the atmospheric environment, realizing the recycling of resource utilization and reducing dependence on external gas resources.
Reduce dust and smoke
The air-assisted system can reduce the dust and smoke generated during laser processing and reduce pollution to the environment.
Improve the cleanliness of the production process
The use of air cutting technology can reduce pollution at the processing site, meeting the requirements of clean production processes.
Summary
Through the above content, we can fully understand the importance, working principle and maintenance of the air assist system of the laser engraver to ensure the efficient and safe operation of the laser engraving machine.
