Product model: High power laser fiber cutting machine
The customized beam shape in fiber laser cutting machines is based on a principle that, compared to traditional laser cutting using a single circular laser beam, the new cutting process adopts a complex laser beam shape
The situation. By utilizing the unique focusing characteristics of high-power single-mode fiber lasers, complex beam shapes can be generated, making it possible to separate a portion of the overall laser energy in order to create a "keyhole"
In laser welding or laser cutting applications.
The remaining energy will be distributed to the melt; Prior to this, the main beam was used to create an appropriate high vapor pressure distribution on the surface of the molten material. This allows it to apply local pressure on the incision outflow
On the melt, this far exceeds the pressure of coaxial gas injection commonly used in laser cutting. The result is that the incision is very narrow.
The new process has great potential, as it does not produce burrs within a large cutting speed range, and can also perform high-speed cutting in narrow contour cutting, producing high-quality incisions.
