Laser cutting technology is a new technology developed in recent decades. And with the improvement of the power level of laser components, the improvement of stability and reliability, and the improvement of processing technology, the type of fiber cutting machine has gradually grown, and there are more and more fiber cutting machines on the market. The quality is also uneven, if you encounter some problems in the process of using the fiber laser cutting machine, here, you can find some solutions to the common problems of the fiber laser cutting machine.

First of all you need to know how the fiber laser cutting machine works?

Laser cutting is to irradiate the workpiece with a high power density laser beam to rapidly 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, controlled by the numerical control mechanical system, and the workpiece is cut by moving the spot position.

Secondly, is the operation of the fiber laser cutting machine dangerous?

Laser cutting is an environmentally friendly cutting method that is harmless to the human body. Laser cutting produces less dust, light and noise than plasma and oxygen cutting. Personal injury or machine damage may result even if proper operating methods are not followed.

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

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

3. Don’t stare at the laser cutting process. It is forbidden to observe the laser beam through a lens such as a magnifying glass to avoid eye damage.

4. Do not place explosives between explosives.

What factors will affect the cutting accuracy of fiber laser cutting machine?

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

How to find the focus position of fiber laser cutting machine?

The influence of the beam power density of the fiber laser on the cutting speed is very important, so it is particularly important to choose an accurate focus position. Since the expansion of the laser beam is proportional to the length of the lens, we can take advantage of this feature, and there are three easy ways to find the cutting focus position in the industry documentation:

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

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

3. Find the blue spark: Remove the nozzle part, blowing part, stainless steel plate on the machine, move the laser head up from the top, until you find the blue spark as the focus.

Currently, many manufacturers’ machines have autofocus. The auto-focus function can significantly improve the efficiency of the laser cutting machine and greatly shorten the time for punching holes on thick plates; the machine can automatically adjust to find the focus position according to different materials and thicknesses.

How many finer laser machines are there? What is the difference between them?

At present, the laser cutting machines 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 for high-precision and confidential processing. Fiber matrix fiber lasers have obvious advantages in lowering the threshold, reducing the range of oscillation wavelength and wavelength tunability, and have become an emerging technology in the laser industry.

What thickness can a fiber laser cutting machine cut?

At present, the cutting thickness of laser cutting machine is less than 25mm. Compared with other cutting methods, laser cutting machines have obvious advantages in cutting materials smaller than 20mm, and require high precision.

What is the application range of laser cutting machine?

Laser cutting machines have the advantages of high 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.
