What can fiber laser cutting machine?

As mentioned above, the wavelength of CO2 laser and solid-state laser such as YAG or fiber laser determines that the former is more easily absorbed by non-metals, and can cut non-metallic materials such as wood, acrylic, PP, organic glass, etc. with high quality, while the latter is not easily absorbed by non-metals. Moreover, the wavelengths of the two differ by an order of magnitude, which greatly increases the flexibility of fiber laser processing.

But both CO2 and YAG laser are helpless when encountering highly reflective materials such as copper and pure aluminum. It always fail to cut a highly reflective material using CO2 laser anyway, because the power or beam transmitted to the material will be reflected back. The YAG laser is only used for thin plate cutting below 8mm.

CNC fiber laser cutting machine does not have these limitations.

However, Senfeng does not recommend using fiber laser for long-term cutting of highly reflective materials. The so-called high reflection has little to do with the smoothness of the cutting surface of the sheet, mainly because the wavelength of the laser is not within the ideal absorption range of these materials. Most of the energy is reflected back, which is easy to damage the protective lens in front of the laser head. If it is used for a long time, the cutting effect is not as expected, but also increase the consumption of consumables.

In the same way, fiber laser cutting equipment cannot process non-metals such as fabrics, leather, and stones, and the advantages of non-metal cutting are not obvious.
