Wood laser cutting machine is a laser device that uses CO2 laser source to carve and cut wood to make 2D or 3D handicrafts. It uses numerical control system to control machine carving and wood cutting. The operation is very simple. It only takes a few steps to complete the production of a wood cutting.
The operation of the wood laser cutting machine is very simple, but there are still many matters needing attention for the initial users of the laser machine. Now let's take stock of the matters needing attention.
Because laser cutting wood uses laser energy to melt wood, blackening will occur during the cutting process. Generally, wood with a thickness of less than 5mm will not blacken too much. However, when cutting wood boards with a thickness of more than 5mm, improper operation will cause serious blackening.
For this problem, the following methods can be used to reduce or avoid wood blackening during laser cutting.
1. Set ideal cutting parameters
High speed and low power are used for laser cutting. It should be noted that the faster the cutting speed is, the better the power is. Because the faster the speed is, the lower the power is, the harder it is to cut in. If the cutting is not ideal and multiple cutting is required, the carbonization and blackening will be more serious. Therefore, it is necessary to ensure a successful cutting.
According to our cutting test, 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 requires the user to test according to the cutting material and specific cutting thickness to obtain the best value.
2. Use auxiliary gas
Another important factor to avoid laser cutting wood blackening is blowing. Compressed air is introduced into the cutting gap through the nozzle, which can make the dust and heat be removed faster. In addition to preventing wood from blackening, auxiliary gas can also reduce the risk of burning wood by CO2 laser cutting. As you gain more experience in using the wood laser cutting machine, you will know how to use air assistance to obtain the best cutting effect through repeated experiments.
3. Adjust the laser focus
You can switch the settings on the laser machine to manual, and then exit the laser focus. Manually adjust the laser focus to make it slightly smaller. More dispersive lasers can reduce the amount of smoke generated, while still providing enough energy to carve or cut your woodworking projects.
The above methods can help you to get the cleanest cutting edge when cutting wood. In addition to taking measures in the cutting process, you can also avoid the problem of laser cutting blackening by selecting more suitable wood. For example, softer wood with simple texture patterns is often more suitable for laser cutting machines.
The wood laser cutting machine adopts non-contact cutting, which can minimize the cutting deformation. Moreover, the edge of the wood cut by laser is smooth without burr, which does not need to be polished in the later stage, thus reducing the labor time. Even if you leave a mark on the finished product when cutting wood with laser, there is no need to worry too much. In most projects of laser cutting wood, brown or amber color on the edge will not damage these projects.
The ability of laser cutting wood has a lot to do with the laser power. ACCTEK Factory has CO2 laser cutting machines in the power range of 80W to 300W for you to choose from. You can customize different laser power and laser cutting table size to suit your wood cutting and carving plan.
