With the continuous advancement of science and technology, various types of fiber optic metal laser cutting machines are also known to more people. Laser cutting, as its name implies, is to irradiate extremely dense light beams to the surface of the material to be processed, light energy generates heat energy, and a large number of light beams make the workpiece instantaneous Heat to extremely high temperature for cutting. In order to ensure the cutting quality and cutting speed, we also need to use auxiliary gas. Different auxiliary gas will also make the cutting surface and affect different.
Laser fusion cutting is to use auxiliary gas to blow out the melted liquid when the processed material is locally heated and melted by the laser. Because it occurs in a liquid state, we call it fusion cutting.
For our metal laser cutter, the laser beam is matched with high-purity inert cutting gas to drive the molten material to leave the kerf, and the gas itself does not participate in the cutting. Laser melting cutting can get a higher cutting speed than gasification cutting.
The laser flame cutting in the metal laser cutting machine is to increase the heat energy by oxygen, and the interaction between the heated metal, so that the material is further heated. This method has the advantages of high efficiency and high speed for the same thickness of metal steel. The difference between laser melting and cutting is that oxygen is used as an auxiliary gas for cutting. The disadvantage is that it will affect the quality of the cut. The material will have burrs after cutting, and the roughness will be large after all. Laser Cutting Methods
This is what we are currently using in many волоконный лазер cutting machines. In the process of laser gasification and cutting, the material is gasified at the slit. In this case, very high laser power is required to instantly generate extremely high heat energy. Laser Cutting Methods
Moreover, to avoid condensation of vapor when the material evaporates, the thickness of the material must not exceed the diameter of the laser beam too much. These conditions limit the application fields of fiber laser cutting machines, and cannot process materials such as ceramics and wood. Now they are widely used in metal materials, such as carbon steel, stainless steel, and aluminum alloys.
