Why is the air compressor important to the fiber laser cutting machine?

Fibre laser cutting machine as an important equipment for metal processing has a wide range of applications in aviation, automotive, machinery and other fields. And the air compressor is an important part of the fibre laser cutting machine, which can provide high-pressure, dry and stable compressed air for the cooling of the laser generator, the cleaning of the air circuit system and the supply of cutting gas. During the laser cutting process, the air compressor plays an important role and directly impacts the cut’s quality. This article will introduce the importance of air compressors to fibre laser cutting machines from the following four aspects:

Why choose air compressor?

Air compressor has a great impact on the cutting quality, mainly reflected in the following aspects:

Pressure: The higher the pressure, the greater the flow and speed of the cutting gas, and the greater the depth and width of the cut. However, too high or too low pressure will affect the cutting effect, so choose the right pressure according to the material and thickness.
Dryness: The higher the dryness, the better the purity and stability of the cutting gas, and the higher the quality and life of the cutting. However, too low a dryness will lead to impurity and instability of the cutting gas, resulting in oxidation, discoloration, and deformation of the cutting edge.
Temperature: the lower the temperature, the lower the density and expansion coefficient of the cutting gas, and the better the cutting effect and energy consumption. However, too high or too low temperature will affect the cutting effect, so use equipment such as coolers and heat exchangers to ensure the temperature, generally required between 15°C and 25°C

3 Main Advantages of air compressors

  1. Firstly, the air compressor can provide enough air pressure to the laser cutting machine to ensure a stable gas supply. Laser cutting machines require high-pressure gas to drive the cutting head, which produces a high-energy laser beam. If the air pressure is unstable or insufficient, it will directly affect the cutting speed and cutting quality. Therefore, the operational stability of the air compressor directly affects the quality of the cut.
  2. Secondly, the air compressor can filter and purify the air to ensure the cutting quality. In the laser cutting process, the impurities and moisture in the air will hurt the cutting effect. The air compressor filters out the impurities and moisture in the air through equipment such as filters and dryers, making the cutting process more stable and reliable.
  3. In addition, it can clean the air circuit system. The air compressor filters out impurities and moisture from the air through equipment such as filters and dryers, making the cutting process more stable and reliable.

Main Types of air compressors

The type of air compressor will also have an impact on the cutting effect of the laser cutting machine.
There are two common types of air compressors on the market today: piston air compressors and screw air compressors. Piston air compressors are suitable for small and medium-sized laser cutting machines, with good efficiency and stability. Screw air compressors are suitable for large laser cutting machines and offer high energy efficiency and high air outlet pressure. Therefore, choosing the right type of air compressor can improve the efficiency and cutting quality of the laser cutting machine.

4 Maintenance precautions of air compressor

The use and maintenance of air compressors need to follow certain norms, such as regular replacement of filter elements, oil-water separator, lubricating oil, etc., to keep the air compressor clean and ventilated, and to avoid overloading, overheating and leaking of the air compressor, etc., to ensure the normal operation of the fiber laser cutting machine and the cutting effect. The following are some common air compressor maintenance considerations:

Check the working condition of the air compressor: Before using the air compressor, you should check the working condition of the air compressor, such as whether the power supply, switches, instruments, valves, pipelines, etc. are normal, whether there is any abnormal sound, vibration, temperature, smell, etc. If you find any problem, you should deal with it or report it for repair promptly, to avoid affecting the performance and safety of the air compressor.
Clean the filter element of the air compressor: the filter element is an important part of the air compressor, it can filter out the dust, moisture, grease and other impurities in the air to ensure that the compressed air is dry and pure. The filter element will be gradually clogged during use, affecting the efficiency and life of the air compressor. Therefore, the filter element needs to be cleaned or replaced regularly, usually every 3 months or every 500 hours, and every 6 months or every 1000 hours.

Replace the oil-water separator of the air compressor: the oil-water separator is an important part of the air compressor, which can separate the oil and water in the compressed air to ensure the dryness and purity of the compressed air. The oil-water separator will gradually fail during use, affecting the efficiency and life of the air compressor. Therefore, the oil-water separator needs to be replaced regularly, usually every 12 months or every 2000 hours.
Replace the lubricating oil of the air compressor: Lubricating oil is an important part of the air compressor, it can lubricate the moving parts of the air compressor, and reduce the wear and tear and heat, to ensure that the air compressor is smooth and efficient. The lubricating oil will gradually deteriorate during use, affecting the efficiency and life of the air compressor. Therefore, the lubricant needs to be changed regularly, usually every 6 months or every 1000 hours.

Conclusion

In conclusion, the air compressor is very important in the laser cutting machine. It has a direct impact on the cutting quality, can provide a stable gas supply, and filter and purify the air. Choosing the right type of air compressor and maintenance specifications can improve the efficiency and cutting quality of your laser cutting machine. If you have a sufficient budget, you can purchase an air compressor configuration to further improve the cutting quality.
