Laser cutting machine cutting 7 kinds of metal, tips about high quality cutting
Because carbon steel contains carbon, the reflection of the laser is not strong, and the absorption beam is very good. Carbon steel is suitable for laser cutting processing in all metal materials. Therefore, carbon steel laser cutting machine has an unshakable position in carbon steel processing.
The application of carbon steel is becoming more and more extensive. Modern laser cutting machines can cut the maximum thickness of carbon steel plates up to 20MM. The slit of carbon steel can be controlled within a satisfactory width range by the oxidation melting cutting mechanism. To about 0.1MM.
Laser cutting stainless steel uses the energy released when the laser beam is irradiated to the surface of the steel plate to melt and evaporate the stainless steel. For the manufacturing industry that uses stainless steel sheets as the main component, laser cutting stainless steel is a fast and effective processing method. The important process parameters affecting the cutting quality of stainless steel are cutting speed, laser power, air pressure and so on.
Compared with low carbon steel, the laser power and oxygen pressure required for stainless steel cutting are higher. Although stainless steel cutting achieves a satisfactory cutting effect, it is difficult to obtain a seam with no sticky residue. The method of laser beam coaxial injection blows away molten metal so that no oxide is formed on the cutting surface. This is a good method, but it is more expensive than traditional oxygen cutting. One way to replace pure nitrogen is to use filtered plant compressed air, which consists of 78% nitrogen.
When laser cutting the mirror stainless steel, in order to prevent serious burns to the plate, a laser film is required!
Aluminum and alloy
Although laser cutting machine can be widely used in the processing of various metallic and non-metallic materials. However, some materials, such as copper, aluminum and their alloys, are difficult to process due to their own characteristics (high reflectivity).
At present, laser cutting of aluminum plates is widely used by fiber lasers and YAG lasers. Both devices, whether cutting aluminum or other materials, such as stainless steel and carbon steel, have good performance, but they cannot be processed thick Aluminum. Generally, the maximum thickness of 6000W can be cut to 16mm, and 4500W to 12mm, but the processing cost is high. The auxiliary gas used is mainly used to blow away the molten product from the cutting zone, and usually a better cut quality can be obtained. For some aluminum alloys, care should be taken to prevent micro-cracks on the surface of the slit.
Copper and alloy
Pure copper (purple copper) cannot be cut with a CO2 laser beam due to its high reflectivity. Brass (copper alloy) uses higher laser power, and the auxiliary gas uses air or oxygen to cut thinner plates.
Titanium and alloys
The laser cutting of titanium alloy commonly used in aircraft industry is of good quality. Although there will be a little sticky residue at the bottom of the slit, it is easy to clean. Pure titanium can be well coupled with the thermal energy converted by the focused laser beam. When the auxiliary gas uses oxygen, the chemical reaction is fierce and the cutting speed is fast. However, it is easy to form an oxide layer on the cutting edge. Inadvertently, it will also cause over-burning. For the sake of stability, it is better to use air as the auxiliary gas to ensure the cutting quality.
Most alloy structural steels and alloy tool steels can obtain good trimming quality by laser cutting method. Even for some high-strength materials, as long as the process parameters are properly controlled, straight, non-sticky slag trimming can be obtained. However, for tungsten-containing high-speed tool steels and hot die steels, erosion and sticky slag will occur during laser cutting machine processing.
There are many varieties of nickel-based alloys. Most of them can be oxidized, melted and cut.
