Today, laser cutting machines have been widely used in all walks of life, equipment development and technological updates are becoming faster and faster. However, many customers still have many problems when cutting thick plates, mainly in two aspects.
Cutting combustion process is easy to fluctuate, resulting in cutting difficulties. Laser cutting of steel plates with a thickness of less than 10mm is no longer a problem, but if you want to cut plates with a thickness greater than 10mm, high-power laser support is usually required, and the cutting quality is also significantly reduced, which is mainly related to the combustion instability of the cutting front.
On the other hand, the iron oxide produced during the combustion process will also hinder the diffusion of oxygen, resulting in a lower combustion temperature. In order for the combustion process to continue, the temperature at the top of the gap must reach the ignition point.
Due to the cost of high-power laser equipment, its output laser mode is not conducive to laser cutting, so the traditional laser cutting method has no advantage in cutting thick plates. Due to the intense burning of the laser radiation area, the oxygen concentration will be reduced, which will also cause the temperature of the blade to fluctuate, which will cause the blade mass to fluctuate with the blade temperature.
