A wood laser cutting machine is a laser equipment that uses a CO2 laser source to engrave and cut wood to create 2D or 3D crafts. It uses CNC system to control the machine to carve and cut wood, it is easy to operate, you only need a few steps to complete a woodworking project.
Although the operation of laser wood cutting machines are very simple, there are still many things to be aware of for laser machine beginners. This article provides you with a guide for using a wood laser cut machine, hoping to help you operate the machine.
Since laser cutting wood uses laser energy to melt the wood, blackening occurs during the cutting process. Usually, cutting wood below 5mm thickness will not darken too much. When cutting boards with a thickness of more than 5mm, improper operation will cause serious blackening. For this problem, blackening of laser cut wood can be avoided by the following methods.
1. Set ideal cutting parameters
Use high speed and low power when laser cutting. It should be noted that faster cutting speed is not always better, lower power is better. Because the faster the speed and the lower the power, the harder it will be to cut in. If the cutting is not ideal, multiple cuttings are required, and the carbonization blackening phenomenon will be more serious. Therefore, we must first ensure a successful cutting.
According to our cutting tests, fast speed is more important than low power. Therefore, you can try to obtain the lowest power at the fastest cutting speed, which is the ideal cutting parameter. Of course, this needs to be tested by the user according to the cutting material and specific cutting thickness to obtain the best value.
2. Use auxiliary gas
Another important factor in avoiding blackening of laser-cut wood is blowing air. Compressed air is directed into the cutting gap through nozzles, which allows for faster removal of dust and heat. In addition to preventing blackening of wood, assist gas also reduces the risk of burning wood with CO2 laser cutting
. As you gain more experience with wood laser cutter, you will learn by trial and error about using air assist to get the best results.
3. Adjust the laser focus
You can switch the setting on the laser machine to "manual" and then exit the laser focus. Manually adjust the laser focus to zoom out slightly. A more dispersed laser can reduce the amount of smoke produced while still providing enough energy to engrave or cut your woodworking project.
The above methods will help you get the cleanest possible cut edge when cutting wood. In addition to taking a way during the cutting process, you can also avoid the problem of blackening with laser cutting by choosing a more suitable wood. For example, softer woods with simple grain patterns tend to be better suited for laser cutters.
The wood laser cutting machine adopts non-contact cutting, which can minimize cutting deformation. Moreover, the edge of the wood after laser cutting is smooth and burr-free, no post-grinding is required, and labor time is reduced. Even if you end up with marks on the finished product when laser cutting wood, there is no need to worry too much. In most laser-cut wood projects, leaving a brown or amber color on the edges won't spoil those projects.
The ability of laser cutting wood has a great relationship with the laser power. ACCTEK factory has CO2 laser cutter for sale
in the power range of 80W-300W for you to choose. You can customize different laser powers and laser cutting table sizes to suit your wood cutting and engraving plans.
