Laser cutting uses the laser beam as the heat source for hot cutting, its working principle is similar to laser welding. The temperature of laser cutting exceed 11000 ℃, which would have made any material gasification, therefore gasification also plays an important role in addition to the melting during laser cutting process.

Laser cutting machine is now the most advanced mechanical processing equipment, laser is first used in the field of mechanical processing, brought unprecedented promotion to the development of mechanical processing.

How Fiber laser Cutting Machine Work?

Fiber laser machine is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing. Fiber nonlinearities, such as stimulated Raman scattering or four-wave mixing can also provide gain and thus serve as gain media for a fiber laser.

Laser cutting machine working principle

The core part of the machine tool is one of the laser generator, it is the core of the whole equipment.Why do you say so?Because it is the secret of the cut metal device.It can convert electrical energy into light energy, release the remarkable feats of laser beam, and with a lot of energy, laser beam by irradiation in sheet metal surface, make the light surface quickly reaching high temperature, radiation surface melting and evaporation of components, through the displacement of the cutting head to achieve the purpose of cutting and engraving.

Generally there are many kinds of laser cutting machine laser, can according to different material to different kinds of laser cutting machine.We have in common solid laser material as medium, its representatives have solid YAG laser cutting machine.With gas as the medium of laser, its representative has CO2 laser cutting machine.Based on optical fiber laser medium, its representatives have optical fiber laser cutting machine.The three machining effect and the thickness is different.
