What to pay attention to when processing different metal materials in laser cutting machine
We may process different metal materials in our daily production work. The two parts of the same metal materials need to be paid attention to when they are processed. What is the specific situation? Let's listen to the introduction of experts. At present, the metal materials that need to be processed by laser cutting machines are mainly the following: 1, titanium and alloys. Pure titanium can well couple the heat energy converted by the focused laser beam. When the auxiliary gas is oxygen, the chemical reaction is fierce, and the cutting speed is faster, but it is easy to form an oxide layer on the cutting edge, and it can cause overburn if you are not careful. For the sake of safety, it is better to use air as the auxiliary gas to ensure the cutting quality. The laser cutting quality of titanium alloy commonly used in the aircraft industry is better. Although there will be a little sticky slag at the bottom of the cutting seam, it is easy to remove. 2, nickel alloy. Nickel-based alloys are also called super alloys, and there are many varieties. Most of them can be oxidized fusion cutting. 3. Carbon steel. Modern laser cutting machines can cut carbon steel plates with a maximum thickness of up to 20mm. The cutting seam of carbon steel can be controlled within a satisfactory width by using the oxidation melting cutting mechanism, and the cutting seam for thin plates can be as narrow as about 0.1mm. 4. Stainless steel. Laser cutting is an effective processing tool for the manufacturing industry that uses stainless steel sheet as the main component. Under strict control of the heat input in the laser cutting process, the heat-affected zone of the trimming can be restricted from becoming very small, thereby effectively maintaining the good corrosion resistance of this type of material. 5. Alloy steel. Most alloy structural steels and alloy tool steels can be used to obtain good trimming quality by laser cutting. Even for some high-strength materials, as long as the process parameters are properly controlled, straight, non-sticky slag cutting edges can be obtained. However, for tungsten-containing high-speed tool steel and hot mold steel, there will be erosion and slag sticking during laser cutting machine processing. 6, aluminum and alloys. Aluminum cutting is a melting laser cutting mechanism, and the auxiliary gas used is mainly used to blow away the molten product from the cutting area, and usually a better cut surface quality can be obtained. For some aluminum alloys, attention should be paid to prevent the occurrence of intercrystalline micro-cracks on the surface of the slit. 7, copper and alloys. Pure copper (red copper) basically cannot be cut with CO2 laser beam due to its high reflectivity. Brass (copper alloy) uses higher laser power, and the auxiliary gas uses air or oxygen, which can cut thinner plates.
