How to Select the Best Process Gas Supply Method for a 12kw and less Laser Cutting Machine?

Low to medium power (<12kw) laser cutting machines, with their efficient and precise processing capabilities, play a significant role in various industries. They are not only suitable for the field of metal processing, offering notable advantages for cutting metal components with complex shapes and fine structures, but are also widely used in the electronics industry for cutting circuit boards and precision components. In the automotive manufacturing industry, low to medium power laser cutters enable rapid and accurate cutting of automotive parts, enhancing production efficiency. Moreover, the high-precision cutting requirements of the aerospace sector have made low to medium power laser cutters an indispensable piece of processing equipment. At the same time, in the manufacturing of medical devices, low to medium power laser cutters are also widely applied due to their high precision and cleanliness requirements for material cutting.

Laser cutting with a power of 12kw or less has been widely applied in various industries due to its characteristics of high precision, high efficiency, and non-contact processing, especially suitable for the processing of thin plate materials and precision parts. To ensure the correct execution of the cutting process, different materials require various types of process gases for laser cutting. However, currently, on the market, fiber laser cutting equipment, in the processing scenarios, has many common pain points regarding the use of process gases:

• Oxygen cutting of carbon steel is inefficient, resulting in oxidation scale on the cut surface;
• Cutting stainless steel with liquid nitrogen is costly;
• Air cutting of carbon steel leads to slagging, increased manual grinding, deburring machine, and grinding consumables/electricity costs;
• Using air cutting can easily cause pipe contamination, affecting cutting quality, and increasing the frequency of optics replacement;

In order to ensure cutting quality and effectively reduce cutting costs, Raysoar introduces a new developed series of one-stop process gas supply system tailored for medium and low-power laser cutting - the Bright Cutting Series. With this system  you can escape from the troubles of gas container and liquid nitrogen and oxygen storage tanks.

The advantages include:

• Compared to traditional liquid nitrogen cutting of carbon steel and stainless steel, costs can be saved by more than 50%;
• Compared to traditional liquid oxygen cutting of carbon steel, efficiency can be increased by 2-3 times;
• Compared to traditional liquid nitrogen cutting of aluminum alloys, the cross-section is smoother, with less slag, and medium-thin aluminum alloy plates can achieve burr-free cutting;
• Compared to traditional air cutting, the gas quality is superior, reducing path contamination.  

PSA Nitrogen Generation Principle Ensures Quality of Nitrogen Output

The Bright Cutting laser process gas supply solution mainly utilizes the principle of Pressure Swing Adsorption (PSA) to separate oxygen and nitrogen from the air. PSA is an advanced gas separation technology that holds an irreplaceable position in the field of on-site rapid gas supply and cost savings. It uses high-quality carbon molecular sieves (CMS) as the adsorbent and employs the Pressure Swing Adsorption principle (PSA) at room temperature to separate air and produce high-purity nitrogen.

Multi Function Available meets the high-quality cutting requirements for various sheet materials.

The Bright Cutting Process Gas Supply System can output nitrogen of different purities according to various processing materials, and different working modes meet the cutting requirements for different materials. For cutting of stainless steel bright surface, it outputs a continuously stable 99.99% high-purity nitrogen, achieving cutting quality equivalent to liquid nitrogen on the basis of reducing cutting costs, which can truly realize non-oxidizing bright surface cutting, meeting the requirements by different cutting users. In addition to stainless steel cutting, this gas supply system can also be set to cutting modes for carbon steel and aluminum alloy. By setting the working mode with one key, it is easy to switch between cutting modes. The flow rate and purity of nitrogen are precisely controllable, achieving high-quality cutting of carbon steel and aluminum alloy.

What’s more,high-end models of the machine can be equipped with 2~4 laser cutting machines, completing the centralized process gas supply simultaneously, perfectly interpreting the economic and efficient cutting scenarios.
