Laser cutting machine to cut a variety of materials need to pay attention to
With the development of laser cutting technology, the field of laser cutting is becoming more and more extensive, and more and more materials are available. However, different materials have different characteristics, so there are different things to be aware of when using laser cutting. The senior engineers of the laser cutting machine below have prepared the precautions for laser cutting for different materials.
First, the steel structure
Good results are obtained when the material is cut with oxygen. When oxygen is used, the cutting edge is slightly oxidized. Metal laser cutting machine For high thickness cutting of 4mm plate, nitrogen can be used as processing gas for high pressure cutting, and the cutting edge will not be oxidized. For plates with a thickness of 10 mm or more, special plates are used and oil is applied to the surface of the workpiece during processing to obtain better results.
Second, stainless steel
Cutting stainless steel requires: using oxygen, where edge oxidation does not matter; use nitrogen to obtain an oxidized, burr-free edge. Coating the oil film on the surface of the board will result in better perforation without sacrificing processing quality.
Third, aluminum
Despite the high reflectivity and thermal conductivity, aluminum with a thickness of less than 6 mm can be cut, depending on the alloy type and laser capability. When cut with oxygen, the cutting surface is rough and hard. When nitrogen is used, the cutting surface is smooth. Pure aluminum is very difficult to cut because of its high purity, and can only be cut when a "reflective absorption" device is installed on the fiber laser cutting machine system. Otherwise the reflection will destroy the optical components.
Fourth, titanium
The titanium plate was cut with argon and nitrogen as processing gases. Other parameters can be referred to nickel-chromium steel.
