First, we need to make it clear that the optical fiber laser cutting machine belongs to the category of metal cutting machine, so generally can only be used to metal processing, non-metallic materials can not be processed, such as stone, glass and other materials.
The reason is that the wavelength range of fiber laser cutting machine is not in the absorption range of this type of material, or is not suitable for absorption, can not reach the ideal range.
Second, the optical fiber laser cutting machine is unable to cut the density plate, optical fiber laser cutting machine belongs to the hot processing, cutting density plate will cause combustion, so that the cutting edge will burn, can not meet the requirements of cutting.
This kind of material basically is the raw material of fiber board, woodiness fiber, plant fiber, still have the material such as the artificial board that a few are to apply urea formaldehyde resin, adhesive to make.
These types of materials belong to the category of density plate, which cannot be processed by optical fiber laser cutting machine at present.
Three, as well as some of the high reflective material, such as metal materials such as copper, although this type of material to use of optical fiber laser cutting machine for cutting, but as a result of these materials for laser wavelength is beyond the scope of these materials an ideal absorption, will reflect energy burned protection lenses, it is also need to be aware of.
