At present, the popular cutting machine used in the market as a laser cutting process is the fiber laser cutting machine. Its excellent characteristics such as wide laser cutting coverage, faster laser cutting speed, very good laser cutting effect and maintenance free are widely used. Especially in the laser cutting of sheet metal materials, fiber laser cutting machine has more advantages. Then the fiber laser cutting machine laser cutting which materials, and listen to Xiaobian together.
1. High carbon steel. When the optical fiber laser cutting machine uses O2 as the production and processing vapor, the laser cutting edge will be slightly oxidized. For plates with a thickness of 4mm, N2 can be used as the production and processing vapor to carry out high-pressure laser cutting. In this case, the edge of laser cutting is not easy to be oxidized. For plates with a thickness of more than 10mm, applying a unique plate to the laser of the steel laser cutting machine and oiling the surface of the product workpiece during production and processing can obtain a better practical effect.
2. Copper and brass. Both materials have high transmittance and very good thermal conductivity. Brass with thickness less than 1mm can be cut by N2 laser; Copper with a thickness of less than 2mm can be laser cut, and O2 must be used in the production and processing of steam. Copper and brass can be laser cut only when the "reflection absorption" device is installed on the system software. Otherwise, the reflection will destroy the electronic optical components.
3. Stainless steel, which is the most selected in all fields. When laser cutting stainless steel, the fiber laser cutting machine applies N2 to obtain the edge without oxidation and burr under the condition that the edge is not affected by oxidation. Coating oil film on the surface of the sheet will get a better practical effect of punching, and it is not easy to reduce the production and processing quality.
4. Aluminum. Aluminum for fiber laser cutting machine, although it has high transmittance and thermal conductivity, aluminum with a thickness of less than 6mm can be laser cut, which depends on the alloy type and laser working ability. When cutting with oxygen laser, the laser cutting surface is rough and hard. When using N2, the laser cutting surface is smooth. Pure aluminum is very difficult to laser cut because of its high purity. Only when the "reflection absorption" device is installed on the system software of the fiber laser cutting machine can laser cut aluminum. Otherwise, the reflection will destroy the electronic optical components.
5. Titanium. Titanium sheet is laser cut with argon and N2 as production and processing vapor. Other main parameters can refer to nickel chromium steel.
