We have been talking about the wide application of laser cutting equipment. No matter what kind of metal sheet, the laser cutting equipment can cut. So what kind of materials can the laser equipment cut in our daily operations? Is it really possible to achieve a perfect cut during the cutting process? This requires us to be able to master the use of clinker during the use process, and pay attention to related matters to maximize the performance of laser cutting equipment.
At present, the main laser cutting machines for processing metal materials on the market are as following:
Stainless steel sheet is the mainstream component in the manufacturing market at present. The efficiency and effect of processing by laser cutting machine is the best method. Under the strict control of heat input in the laser cutting process, the heat-affected zone of the cutting edge can be restricted to be very small, thereby effectively maintaining the good corrosion resistance of such materials.
The modern laser cutting machine can cut the maximum thickness of carbon steel plate up to 20MM. The slit for cutting carbon steel using the oxidative melting cutting mechanism can be controlled to a satisfactory width range, and the slit for thin plates can be narrowed to about 0.1mm.
3.Aluminum and aluminum alloy
Aluminum cutting belongs to the melting laser cutting mechanism. The auxiliary gas used is mainly used to blow away the molten product from the cutting zone, and usually a better cut surface quality can be obtained. For some aluminum alloys, care should be taken to prevent micro-cracks on the surface of the slit.
Laser cutting can be used for most alloy structural steels and alloy tool steels to obtain good cutting edge quality. Even for some high-strength materials, as long as the process parameters are properly controlled, straight and slag-free cutting edges can be obtained. However, for tungsten-containing high-speed tool steels and hot-mold steels, erosion and slagging can occur during laser cutting.
5.Titanium and titanium alloys
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, and accidental overburning can also occur. For the sake of stability, it is better to use air as the auxiliary gas to ensure the cutting quality. Laser cutting of titanium alloys commonly used in the aircraft industry has good quality. Although there will be a little sticky slag at the bottom of the slit, it is easy to remove.
6.Copper and copper alloys
Pure copper (copper) cannot be cut with a CO2 laser beam due to its too high reflectivity. Brass (copper alloy) uses higher laser power, and the auxiliary gas uses air or oxygen, which can cut thinner plates.
Nickel-based alloys are also called super alloys, with many varieties. Most of them can be subjected to oxidative fusion cutting.
