How To Stop Sheet Metal Laser Cutting Machine Based On Material Characteristics
2019-09-16


In the 21st century against industrialization, the word sheet metal laser cutting machine is no longer unfamiliar. It has taken a position to be replaced in our industrial production. With the growth of technology, the scope of laser cutting applications is becoming more and more common, and more and more materials are available. However, the divergent materials have different characteristics. In addition, the laser cutting is to stop the cutting of the material by burning the low-temperature melting material. Therefore, the chemical reaction caused by the laser cutting of the different materials is also different, so that the material is stopped. At the moment of laser processing, we must stop the laser processing according to the characteristics of the divergent materials to obtain the processing result of double ambition. Next, Perfect Laser will be used for everyone to apply the laser cutting effect of ambition based on the divergent characteristics of the material.



1. Structural steel

This material will give better results when cut with oxygen. When oxygen is used as the processing gas, the cutting edge is slightly oxidized. For plates up to 4 mm thick, low pressure cutting can be stopped with nitrogen as the processing gas. In this case, the cutting edge will not be oxidized. For plates with a thickness of 10 mm or more, special plates are applied to the laser and oil can be applied to the outside of the workpiece during processing to obtain better results.


2. Stainless steel

Cutting stainless steel is necessary: ​​the application of oxygen, in the case of edge oxidation does not matter; the application of nitrogen to obtain the edge of the oxidation-free burr, no need to deal with it. Coating the oil film on the outside of the board will result in better perforation without sacrificing processing quality.


3. Aluminum

Even with high reflectivity and thermal conductivity, aluminum with a thickness of 6 mm can be cut, depending on the alloy example and laser capability. When cut with oxygen, the outside of the cut is rough and strong. When using nitrogen, the outside of the cut is slippery. Pure aluminum is difficult to cut due to its high purity. As long as the "reflective absorption" assembly is installed on the system, the aluminum can be cut. Otherwise reflection can damage the optical components.


4. Titanium

The titanium plate was cut with argon and nitrogen as processing gases. Other parameters can refer to nickel-chromium steel. Both copper and brass have high reflectivity and exceptionally good thermal conductivity. Brass having a thickness of 1 mm can be cut with nitrogen; copper having a thickness of 2 mm can be cut, and the processing gas must be oxygen. Copper and brass can be cut as long as the "reflective absorption" assembly is installed on the system. Otherwise reflection can damage the optical components.


5. Decomposition materials

When cutting the material, remember the risks of cutting and the risk materials that can be emitted. Processable decomposition materials are: thermoplastics, thermosoftening materials and elastomers.


6. Organic matter

There is a risk of fire in all organic cutting (using nitrogen as a process gas and compressed air as a process gas). Wood, leather, cardboard and paper can be laser cut and the cutting edges burnt (brown).
