Metal fiber laser cutting machine has become the main force of metal cutting
XT laser – fiber laser cutting machine.
Optical fiber laser cutting machine is known as the tailor of metal processing. It has become the core equipment of manufacturing and processing mainly because of its advantages of good processing quality and high efficiency, and plays an irreplaceable role in various fields. Optical fiber laser cutting machine is simple, fast and efficient in cutting various metals, replacing the traditional process and becoming the mainstream process of metal processing.
Fiber laser cutting machine is widely used in carbon steel cutting. The advantages of the carbon steel laser cutting machine are that it can cut any design pattern on the plate, with high speed and precision, and one-time forming without subsequent processing. The laser cutting machine cuts carbon steel without casting mould, saving cost, visual layout, tight fitting and material saving. Carbon steel is more and more widely used. Xintian Laser-3000W optical fiber laser cutting machine can cut carbon steel plates with a maximum thickness of 20MM. By using the oxidation melting cutting mechanism, the slit of carbon steel can be controlled within a satisfactory width range, and the slit of thin plate can be narrowed to about 0.1MM. Because carbon steel contains carbon, the reflected light is not strong and the absorption light is also good. Carbon steel is the most suitable material for laser cutting machine processing among all metal materials, and its processing effect is also the best. Therefore, the use of carbon steel laser cutting machine in carbon steel processing has an unshakable position.
Stainless steel is widely used, such as kitchen equipment, general wire drawing materials, gas stoves, refrigerators, electrical appliances, building materials, regrinding, elevators, interior and exterior decoration materials, chemical equipment, heat exchangers, boilers, etc. When laser cutting stainless steel, the energy released when the laser beam strikes the surface of the steel plate is used to melt and evaporate the stainless steel. Laser cutting of stainless steel is a fast and effective processing method for the manufacturing industry with stainless steel sheet as the main component.
The most important process parameters affecting the cutting quality of stainless steel are cutting speed, laser power, air pressure, etc. Alloy steel Most alloy structural steel and alloy tool steel can obtain good trimming quality by laser cutting. Even for some high-strength materials, as long as the process parameters are properly controlled, a straight cutting edge without slag can be obtained. However, for tungsten containing high speed tool steel and hot die steel, erosion and slag sticking will occur during the processing of fiber laser cutting machine.
Compared with low carbon steel, stainless steel cutting requires higher laser power and oxygen pressure. Although stainless steel cutting has achieved satisfactory cutting effect, it is difficult to obtain fully adhesive slit. The beam coaxial injection method blows away the molten metal, so that the cutting surface will not form oxides. This is a great method, but it is more expensive than traditional oxygen fuel cutting. One way to replace pure nitrogen is to use filtered workshop compressed air, which contains 78% helium.
Although laser cutting machine can be widely used in the processing of various metal and non-metallic materials. However, some materials, such as copper, aluminum and their alloys, are difficult to be processed by laser cutting due to their own characteristics (high reflectivity). Nickel alloy nickel-base alloy, also known as superalloy, has many varieties. Most of them can be oxidized and melted. Because of its high emissivity, pure copper can not be cut by CO 2 laser beam.
Brass uses higher laser power, and auxiliary gas uses air or oxygen to cut thinner plates. At present, the aluminum plate laser cutting machine has good performance in cutting aluminum plate and other materials, such as stainless steel and carbon steel. Performance, but it can not process thicker aluminum. The auxiliary gas used is mainly used to blow molten products away from the cutting area, usually in order to obtain better cutting surface quality. For some aluminum alloys, attention should be paid to prevent microcracks between grains on the notch surface.
The laser cutting quality of titanium alloys commonly used in the titanium and alloy aircraft manufacturing industry is good, although there will be a little sticky residue at the bottom of the cutting, which is easy to clean. Pure titanium can well couple the heat energy converted by focused laser beam. When the auxiliary gas uses oxygen, the chemical reaction is fierce and the cutting speed is fast, but it is easy to form an oxide layer on the cutting edge, and a slight carelessness will cause burnout. For safety, it is better to use air as auxiliary gas to ensure cutting quality.
