Can laser cutting machine cut wood? At present, traditional sawblade is mostly used to cut wood, but it will produce a lot of sawdust and noise pollution. Cutting wood with laser can not only reduce noise, but also reduce the generation of sawdust particles and reduce the harm to human body. The quality of laser cutting wood slices is also better than that of traditional cutting methods.
There are two basic methods for laser cutting wood: instant gasification and burning. The way of laser cutting wood depends on the power density absorbed by wood. Instantaneous gasification is an ideal method for wood cutting. Under the irradiation of a focused laser beam, the wood is gasified to form a cutting seam. Gasification cutting is characterized by fast cutting speed, less heat transfer to the uncut substrate, no carbonization on the profile, only slight blackening and polishing.
The cutting of combustion mode is mainly due to the low power density of the beam, which is characterized by slow cutting speed, wide cutting seam, large cutting thickness, and smoke and burning smell. The energy consumption per unit material cut by burning is higher than that of the material gasified, and there is carbonization at the cutting edge. However, in the actual wood cutting process, gasification is basically accompanied by combustion, because although the gasification method has the advantages of high efficiency, it requires high power density to achieve it. However, in the actual laser irradiation process, due to the influence of the laser output power and beam mode, there are always areas where the laser beam power density is lower than the power density required for material surface gasification, so there is little chance of combustion.

What kind of laser can cut wood
Generally, CO2 laser is used to cut wood, and its wavelength is 10.6 μ M。 However, the photoelectric conversion rate of CO2 laser is low (only 5% – 10%), and the energy consumption is relatively large; The laser needs frequent air exchange, and the maintenance cost is high. The external optical path is very complex, so it is difficult to install, debug and maintain. Therefore, CO 2 laser is limited in practical industrial production and application.
At present, in the market, fiber laser (wavelength 1 μ m) Cutting sheet metal is very common. Can this fiber laser be used to cut wood? If the wavelength is 1 μ M fiber doped fiber laser cutting wood, the answer is: more difficult. This is because the wood μ The absorption of m wavelength laser is relatively low, and it is difficult to form a slit
