What common materials are not suitable for fiber laser cutting machine to process?

 

Most people think that the fiber laser cutting machine can cut any material, and the processing range should be very wide, and the fiber laser cutting machine generally uses imported lasers, and its processing effect should be very good. But in fact, the fiber laser cutting machine is divided into categories, and each type of equipment has its own processing materials. Here is an introduction.

We know that fiber laser cutting machines are usually equipment for processing metal materials, so they can only cut most metal materials, not non-metals such as cloth, leather, and stones. This is because the wavelength range of the fiber laser cutting machine is not within the absorption range of materials other than most metal materials, or the absorption is insufficient, and satisfactory cutting results cannot be obtained. Under the premise of the current equipment technology, the advantages of non-metal cutting are not very obvious. Of course, the possibility of future development in this area is not ruled out.

For high-reflective metal materials, fiber laser cutting often encounters problems. Equipment manufacturers should advise fiber laser cutting machine users not to cut aluminum, copper and other metal materials for a long time, because these materials are highly reflective materials, and the wavelength of the laser is not It is not very suitable for the absorption of these materials. The absorption rate of the beam energy is very low, and a lot of energy will be reflected to damage the protective lens in front of the laser head, which will increase the consumption of consumables. If you want to cut aluminum and copper, additional special protective devices must be made.

The cutting thickness of the fiber laser cutting machine varies according to its power. The greater the power, the greater the cutting thickness, the thinner the metal material, and the faster the cutting speed. Therefore, the fiber laser cutting machine has obvious advantages for cutting medium and thin plates.
