Guide | Precautions for buying 4000W fiber laser cutting machine


In recent years, the competition around “intelligence” has become increasingly fierce, and it is giving birth to a great change in the production method of the manufacturing industry. With this opportunity, laser cutting machines have become widely used processing equipment in the industrial field. Due to its superior performance, the fiber laser cutting machine is gradually conquering the city. Here, KRRASS will introduce to you what you should pay attention to when buying a 4000W fiber laser cutting machine!

4000W fiber laser cutting machine belongs to high-power laser cutting, generally used for thick plate cutting, and is widely used in engineering machinery, automobile and ship, locomotive sheet metal cutting, aerospace, pressure vessel, military, metallurgical steel rolling and other industries.

We all know that the higher the power of the laser cutting machine, the stronger the cutting ability.


The 4000W laser cutting machine can quickly cut sheet materials with good cutting edge quality. The 4000W laser processing 10mm thick stainless steel is about twice as fast as the 2000W laser processing. For thick plate cutting, high-power laser cutting machines perform better. For example, 4000W laser cutting machine can process carbon steel up to 20mm thick. In the actual application process, the cutting capacity of the 4000 watt fiber laser cutting machine is also related to many factors such as auxiliary gas, laser machine configuration, cutting environment, cutting speed, etc. Therefore, there is no absolute standard to judge its cutting thickness.



When purchasing a 4000W fiber laser cutting machine, you must learn more about it and compare it. On-site inspection is an indispensable process. Don’t trust the text data of major manufacturers. Because some informal manufacturers, the parameters of the product display are one thing, and the cutting effect from the actual performance of the cutting effect is another. It is best to take your own board to make a sample to see if the actual cutting effect can meet the requirements, or go directly to the factory to inspect and conduct a comprehensive evaluation.


There are many brand manufacturers of 4000W fiber laser cutting machine, and generally they will launch related products in big brands. The inspection should be carried out from the following aspects.

  • Laser


Most use imported lasers. Because foreign research and development are earlier, related technologies are more mature, and the quality of lasers is relatively stable, but the price is also higher. The 4000W laser cutting machine of Realdo Laser generally uses imported lasers.


  • Software system


The software system is provided by the manufacturer of the laser cutting machine, and large companies will have a professional technical department to develop and update the CUT software. Its advantages are self-evident, and it is better compatible with the hardware and perfect matching Together, you can maximize the functionality.


  • Accessories and supplies


The core of the laser cutting machine is also the laser. Occasionally, optical isolators, xenon lamps, mechanical consoles, and some water-cooled equipment are also considered. The accessories of optical equipment include half mirror, total mirror, refractor and so on.
