The cutting different effects of fast fiber laser cutter
However, different materials have different characteristics, and fast fiber laser cutter is to cut the material by firing the high-temperature melting material.
Therefore, the chemical reaction of laser cutting for different materials is different. So the material is laser process.
When we do laser processing according to the characteristics of different materials, we will get more ideal processing results.
1. Structural steel
Good results are obtain when the material is cut with oxygen. When oxygen is use as the processing gas. The cutting edge is slightly oxidize.
For plates up to 4 mm thick, high pressure cutting can perform with nitrogen as the process gas. In this case, the cutting edge will not oxidize.
For plates with a thickness of 10 mm or more, special plates are use for the laser .And oil is apply to the surface of the work piece during processing to obtain better results.
2. Stainless steel
Cutting stainless steel requires: using oxygen, if the edge oxidation is not tight.
using nitrogen to obtain an oxidize, burr-free edge, no further processing is require.
Coating the oil film on the surface of the board will result in better perforation without sacrificing processing quality.
3. Aluminum alloy tube
With high reflectivity and thermal conductivity, aluminum with a thickness of 6mm or less can cut. Depending on the alloy type and laser capability.
When cut with oxygen, the cutting surface is rough and hard. When nitrogen is use, the cutting surface is smooth.
Pure aluminum is very difficult to cut because of its high purity. And aluminum can only cut when a “reflective absorption” device is install on the system. Otherwise the reflection will destroy the optical components.
To sum up
For the industrialized 21st century, the term laser cutting machine is no longer unfamiliar.
And it has achieve an irreplaceable position in our industrial production field.
With the development of technology, the field of laser cutting is becoming more and more extensive, and more and more materials are available.
