Answer common questions about fiber laser cutting machine

If you have some questions in the process of using the fiber laser cutter, here, you can find some solutions to the common problems of the fiber laser cutting machine.

How is the fiber laser cutting machine working?

Laser cutting is to illuminate the workpiece with a high-power density laser beam to quickly melt, vaporize, ablate or reach the ignition point. At the same time, the high-speed airflow blows the molten material away. The workpiece is coaxial with the beam and is controlled by CNC mechanical system , Realize the workpiece cutting by moving the position of the light spot.

Is the fiber laser cutting machine dangerous to operate?

Laser cutting is an environmentally friendly cutting method, which is harmless to our body. Compared with plasma cutting machine and oxygen cutting, laser cutting produces less dust, light and noise. Even if you do not follow the correct operation method, it may cause Personal injury or machine damage.

1. Pay attention to flammable materials when using the machine. Some materials cannot be cut with a fiber laser cutting machine, including foam core materials, all PVC materials, high-reflective materials, etc.

2. During the working process of the machine, it is strictly forbidden for the operator to leave to avoid unnecessary losses.

3. Do not stare at the laser cutting process. It is forbidden to observe the laser beam through a lens such as a magnifying glass to avoid damage to the eyes.

4. Do not place explosive materials among explosive materials.

What factors will affect the fiber laser cutter cutting accuracy ?

There are many factors that affect the accuracy. Some factors are caused by the equipment itself, such as the accuracy of the mechanical system, the vibration of the workbench, the quality of the laser beam, auxiliary gas, nozzles, etc. Other factors are caused by the material itself. Caused by properties, such as the physical and chemical properties of the material, the degree of reflection of the material, etc. Other parameters such as parameters can be adjusted according to the specific processing object and user’s quality requirements, such as output power, focus position, cutting speed, auxiliary gas, etc.

How to find the focal position of the fiber laser cutter?

The influence of the laser beam power density of the fiber laser machine is important to the cutting speed, so selecting an accurate focus position is particularly important. Since the expansion of the laser beam is proportional to the length of the lens, we can take advantage of this feature, there are three simple ways to find cutting focus locations in the industry file:

1. Pulse method: Print the laser beam on the plastic plate, move the laser head from top to bottom, check all holes, and focus on the smallest diameter.

2. Inclined plate method: Use an inclined plate below the vertical axis, move it horizontally, and look for the laser beam at the minimum focus point.

3. Find blue sparks: Remove the nozzle parts on the machine, blow parts, stainless steel plates, move the laser head in the direction from the top until you find a blue spark as a focus.

At present, many manufacturers’ machines have auto-focus functions. The auto-focus function can significantly improve the efficiency of the laser cutting machine and greatly reduce the time to punch holes in the thick plate; the machine can automatically adjust to find the focus position according to different materials and thicknesses.

How many types of finer laser machines? What is the difference between them?

At present, laser cutter used for processing and manufacturing mainly include CO2 lasers, YAG lasers, fiber lasers, etc. Among them, high-power CO2 lasers and YAG lasers are more used in high-precision and confidentiality processing. The fiber laser with fiber matrix has obvious advantages in lowering the threshold, reducing the range of the oscillation wavelength and the tunability of the wavelength, and has become an emerging technology in the laser industry.

What is the thickness that the fiber laser cutting machine can cut?

At present, the cutting thickness of the laser cutting machine is less than 25mm. Compared with other cutting methods, the laser cutting machine has obvious advantages when cutting materials less than 20mm, and requires high precision.

What is the application range of laser cutting machine?

Laser cutting machine has the advantages of fast speed, narrow width, good cutting quality, small heat-affected area, and good processing flexibility. Therefore, it is widely used in automobile manufacturing, kitchen industry, sheet metal processing, advertising industry, machinery manufacturing, cabinet processing, elevator manufacturing , Fitness equipment and other industries.
