Precise laser wood cutting exceeds the expectations of machine owners. Original drawings made of valuable material captivate buyers. Manufacturers prefer radiation treatment due to the lack of waste and non-burning edges of the workpieces. The technology does not require a constant change of an expensive tool.
Positive selection criteria
Laser cutting of wood is used to obtain aesthetic patterns on details. The cutting place is exposed to thermal effects. A hard edge is formed that does not require additional protection. This allows you to cut thin materials into fragments of less than 0.6 mm.
We highlight the main advantages that a machine for laser cutting of wood has:
- The quality of the picture due to the high accuracy of processing. Deviation from dividing lines is not more than 0.2 mm. The seam is almost imperceptible. So, the masters achieve clear contours of small details of the pattern.
- The absence of waste simplifies the process. Hence the rational use of the material.
- Saving money consists of two factors: lack of marriage, no purchase of an instrument is required.
- Conversion to another size does not take time. Parameters are loaded in advance into the controller memory.
- Power consumption is reduced due to the exclusion of strong electric motors from the design.
- The machine for laser cutting of wood is capable of multitasking. In addition to cutting blanks, engraving is applied, and it is also used in the processing of other materials: metals, plastic.
Installation device
The dimensions of the machine vary depending on the size of the original workpieces. The clamping table of sheet materials can be of tape type. Laser cutting of wood is carried out with a CO 2 device. The gas method requires air blowing of the treatment area.
The movement of the cutting part occurs along the guides of a lightweight design. Due to the lack of clamping of the tool to the part, the machine is not demanding on the rigidity of the installation. The laser is built on the effect of crossing rays. The central point has the most powerful energy. Therefore, thick parts are cut with an uneven seam. Distortions form a semicircular shape.
disadvantages
Laser cutting on wood with all its advantages has negative aspects:
- At the scene of the beam, the result of heat treatment remains, since it burns through the tree.
- The limited thickness of the workpieces for a high-quality seam is not more than 20 mm.
- If the operator is inexperienced, there is a risk of fire of the workpiece.
- An air cooling unit is required.
- Creating three-dimensional models requires operator training. However, for ease of operation, the conversion of graphic images to machine codes occurs automatically.
The surface of the pattern of metal products becomes dense, hardening occurs. This makes difficulties with other treatments, such as drilling. Some materials are poorly laser treated. These include impregnated plywood. Transparent materials distort the perpendicularity of the beam, which leads to a violation of the boundary of the seam.
Selection recommendations
If laser cutting is required on wood, the price of machines differs from analogues of the contact principle of operation. Their cost starts from 80 thousand rubles. And the price of the procedure itself depends on the thickness of the workpiece and the length of the laser cut (from 30 p. For p / m). The first criterion for analyzing a model is beam power. The thickness of the cut blanks depends on it.
The working stroke of the axes is selected according to the size of the resulting figure. The dimensions of the table depend on the length and width of the workpiece. For cutting material, portable single-coordinate systems can be used.
The electronic control system is selected by the parameter - resolution or discreteness of movement of the cutting part. The quality of the engraving of the parts depends on it.
