laser cutting machineAs we all know, laser can be used for engraving and cutting. Next, we will introduce the principle of laser engraving and cutting


Laser engraving is mainly carried out on the surface of the object, and it is divided into two types: bitmap engraving and vector engraving

1.Bitmap engraving:

We first carry out the screen processing of the graphics we need to engrave in PHOTOSHOP and convert them into monochrome BMP format, and then open the graphics file in the dedicated laser engraving and cutting software. According to the material we are processing, we can set the appropriate parameters, and then click to run, the laser engraving machine will engrave according to the dot matrix effect produced by the graphic file.


2.Vector engraving

Use vector software such as Coreldraw, AutoCad, Illustrator and other typesetting design, and export the graphics to PLT, DXF, AI format, marking machine, and then use the special laser cutting machine engraving software to open the graphic file and send it to the laser Processing in the engraving machine.


3.Laser cutting:

We can understand it as the separation of edges. For such processing purposes, we should first make the graphics in the form of vector lines in CORELDRAW, AUTOCAD, pneumatic marking machine, and then save the corresponding PLT, DXF format, use the laser cutting machine operating software to open the file, according to our The processed material can be run after setting the parameters such as energy and speed. The laser cutting machine will automatically cut according to the flight path generated by the software after receiving instructions from the computer. For example, the existing laser cutting machine can draw a template according to the computer, and then directly input it into the computer to automatically cut the graphics. Existing laser cutting machines generally have their own hard disk, which can input massive data sources.


4.Laser melting and cutting

In laser melting and cutting, the workpiece is partially melted and the molten material is sprayed out with the help of airflow. Because the transfer of the material only occurs in its liquid state, the process is called laser melting and cutting.

The laser beam is matched with a high-purity inert cutting gas to drive the melted material away from the kerf, and the gas itself does not participate in the cutting. Laser melting cutting can get a higher cutting speed than gasification cutting. The energy required for gasification is usually higher than the energy required to melt the material. In laser melting and cutting, the laser beam is only partially absorbed. The maximum cutting speed increases with the increase of the laser power, and decreases almost inversely with the increase of the thickness of the sheet and the increase of the melting temperature of the material. In the case of a certain laser power, the limiting factor is the air pressure at the slit and the thermal conductivity of the material.


5.Laser flame cutting

The difference between laser flame cutting and laser melting cutting is that oxygen is used as the cutting gas. With the help of the interaction between oxygen and the heated metal, a chemical reaction is generated to further heat the material. Due to this effect, for structural steel of the same thickness, the cutting rate that can be obtained by this method is higher than that of melting cutting.


On the other hand, this method may have worse cut quality compared to fusion cutting. In fact, it will produce wider kerf, obvious roughness, increased heat-affected zone and worse edge quality. Laser flame cutting is not good when processing precision models and sharp corners. A pulsed laser can be used to limit the thermal influence, and the power of the laser determines the cutting speed. In the case of a certain laser power, the limiting factor is the supply of oxygen and the thermal conductivity of the material.
