Before making the final decision to purchase laser equipment, we need to know what we want to do with this machine. The market is full of various CO2 laser marking machines, we must make the best choice for future work. To know what a laser can do, we need to know how a CO2 laser marking machine works.
The following knowledge points are listed below:
The laser scheme of CO2 laser marking machine
The wave length of CO2 laser marking machine
The power of CO2 laser marking machine
Adjust the speed of the CO2 laser marking machine
To understand how the CO2 laser marking machine works, it is important to understand how the laser works. The laser beam is emitted by the laser tube on the back of the device. Through the reflection of each mirror surface, the lens is transferred to the head outlet where the lens is installed. It reflects from the mirror at a right angle and emits in the direction of the laser head.
Here, the laser beam is reflected from the last mirror to the direction of the workpiece. Place the focusing lens at the end of the laser head. Collect the radius of the laser beam on the material. The carriage moves along the moving material guide (X axis). The guide rail and mirror surface pass through the material (Y axis). In this way, the car can find materials anywhere.
On the controller screen of the CO2 laser marking machine, you can change the position and speed of the laser head and select the file to be recorded with the USB key or the file directly recorded in the laser memory. You can change the parameters at any time to record or cut and interrupt and resume the laser work. This machine can remember the last file, so in case of a power outage, we can repeat this work.
The laser head of CO2 laser marking machine is software controlled, every 10 and every millimeter. The laser power can be determined by the control panel, and the speed and other parameters are directly controlled by the software.
10600 nanometers or 10.6 micrometers is a wavelength in the frequency range, called mid-infrared. 10600 nm is best used for marking organic materials such as textiles, paper, glass and wood, but also plastic (usually only engraved). 10600mn only has a thermal effect on the material. A carbon dioxide laser (CO2) produces laser light at 10,600 nanometers.
This is the power of the laser beam emitted by the laser tube. The laser uses a service capacity of 25 to 100 watts to record. 30 watts of power is enough to make the traditional materials work properly. This is also a protection for the laser tube in the event of power loss. In mass-produced equipment, greater power is useful. This can shorten the cutting time of various materials.
In the software you cannot directly adjust the laser power in watts, but record and cut the material in percentage. Each material has a different structure and different performance requirements. The dirt of the optical system and the wear of the laser tube will affect the effect of engraving or cutting. The depth of engraving depends on the choice of laser power.
The stronger the power, the deeper marking. Laser tubes have a useful life span, but this useful life span can be reduced in the case of large workloads carried out at maximum power. We can increase the engraving depth by reducing the speed or reducing the dpi resolution of the file.
This is the speed at which the laser head engraves or cuts on the material. The parameter in the software is mm / s. For each material, we have set different marking speeds. Higher speed means faster laser operation. The speed depends on the depth of engraving.
If the laser operation speed is too high, we cannot get the expected results because the design will be recorded. In the case of constant laser power, in order to obtain a better depth of engraving, we need to reduce the speed of laser engraving.
You can increase the speed and decrease the line display to get a lower engraving depth. For laser machines with a laser power of 40 or 60w, such as wood, glass, laminate, aluminum, leather, paper, etc., generally must operate at 20% to 60% power, and the corresponding result is by reducing the speed to the maximum To achieve 20% of the speed.
