Choose fiber laser cuWith the development and adoption of plasma cutting machine, the working gas has a significant impact on the cutting performance, cutting quality and cutting speed of plasma arc. The commonly used plasma arc work and argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gas gas, the plasma cutting machine is widely used in automobiles, motorcycles, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, Steel structure and other industries.

Compared with plasma cutting machine, optical fiber laser cutting machine is more expensive than plasma cutting machine in price, but the cutting quality of optical fiber is better than plasma cutting machine. These two machines are both used to cut metal and belong to metal cutting machine.

Detailed differences between laser cutting machine and plasma cutting machine

1. Compared with plasma cutting, laser cutting is much more accurate, the heat affected area is much smaller, and the gap is much smaller;

2. If accurate cutting is required, the slit is small, the heating area is small, and the plate deformation is small, it is recommended to select the laser cutting machine;

3. Plasma cutting uses compressed air as the working gas, high temperature and high speed plasma arc as the heat source, partially melts the metal to be cut, and blows away the molten metal with high speed air flow to form cutting.

4. Plasma cutting has a large heat affected area and a wide gap, so it is not suitable for cutting thin plates, because thin plates will be deformed due to heat;

5. Cutting speed: 1000W laser cutting 2mm thick low-carbon steel plate, cutting speed can reach 600cm/min. The plasma cutting speed is slow and the relative precision is low, which is more suitable for cutting thick plates, but the end face is inclined.

6. Cutting accuracy: the laser cutting incision is thin and narrow, the cutting seam is parallel to both sides and perpendicular to the surface, and the dimensional accuracy of the cutting parts can reach ± 0.2mm.

7. Gap width comparison: laser cutting is more accurate than plasma cutting. The gap is small, about 0.5mm. The plasma cutting seam is about 1-2mm larger than the laser cutting seam.

We believe that in the future development, laser cutting opportunities will occupy an absolute position in sheet metal processing, including non-metallic cutting, and laser cutting machines will also occupy a considerable part of the market.tter or plasma cutter?
