Why lasers can t cut white fibers

Fiber laser cutting is a kind of thermal processing, which cannot cut the MDF, which will cause melting or burning, so that the cut edge will gelatinize, and the cutting requirements cannot be met.

Laser communication has gone through two important stages of development: atmospheric communication and optical waveguide (optical fiber) communication. In the early days, laser atmospheric communication had set off a worldwide research boom, and many developed countries with strong economic and technical strength had invested a lot of manpower, financial and material resources at this stage to carry out extensive research and development on laser atmospheric communication. Most of the light sources used in early laser-atmosphere communication were carbon dioxide gas lasers, YAG solid-state lasers, He-Ne gas lasers, etc.

The output laser wavelength of carbon dioxide gas laser is in the low-loss window of atmospheric channel transmission, which is an ideal light source for communication. Fiber optic waveguide communication is basically synchronized with the research of laser atmospheric communication technology, so that the laser wireless communication (laser space communication) and laser wired communication (laser fiber communication) corresponding to the traditional communication in laser communication have been formed in technology.

In 1975, the world's first optical fiber communication experimental application line was opened in Chicago, USA, which opened the prelude to the application of optical fiber communication. Since then, with the continuous improvement and maturity of optical fiber production technology, semiconductor device technology and optical communication system technology, optical fiber communication has set off a boom in application all over the world since the 80s, and has been quickly recognized as an important communication means with the most potential for the development of terrestrial wired communication, so that it has been developed and popularized by leaps and bounds. At the same time, due to many objective factors such as device technology, system technology and the instability of the optical transmission characteristics of the atmospheric channel, the laser atmospheric communication technology has not been well solved and made up for a while, and it has retreated almost without a trace in the vigorous optical fiber communication boom.

This involves the problem of laser wavelength (the wavelength of the fiber laser cutting machine is not easy to be absorbed by non-metals, so it cannot cut non-metallic materials);

The reason why the processing scope of the metal laser cutting machine can only cut metal, not cloth, skin, stone and other non-metals, the reason is very simple, the wavelength range of the fiber laser cutting machine is not within the absorption range of the above materials, or the absorption is not suitable, and the ideal cutting effect cannot be achieved.

Secondly, the fiber laser cutting machine is not recommended to cut rare metal materials such as aluminum and copper for a long time, because these materials are highly reflective materials (note: high reflection has little to do with the smoothness of the cutting surface of the plate, mainly because the wavelength of the laser is not within the ideal absorption range of these materials, the absorption effect is not good, most of the energy is reflected back, and it is easy to damage the protective lens in front of the laser head), the long-term use effect is not good, and the use of consumables will be increased;

Finally, the special magnesium laser cutting machine, according to its different power, the cutting thickness of the bottom also changes, the greater the power, the greater the cutting thickness, the thinner the metal material, the faster the cutting speed, the special magnesium fiber laser cutting machine for thin plate cutting advantages are very obvious.

Hello, there are several types of laser cutting machines, which can cut metal and non-metal profiles, and you can choose CO2 laser cutting machine. I hope it can help you, Ou Rui.

The wavelength is different, not suitable for cutting acrylic materials, CO2 laser cutting machine is suitable for cutting!

The fiber laser cutting machine can only cut metal materials, if: stainless steel, galvanized sheet, carbon steel, aluminum, copper and other metals, non-metallic materials can not be cut.

The fiber laser cutting machine is mainly used to cut metal, and the general low-power laser cutting machine can be used to cut acrylic, and the effect is also good, ** is also relatively different, you can go to the new light source to learn about it, they have a professional cutting acrylic machine, and the effect is very good.

Because of the problem of wavelength, it will not be suitable for cutting acrylic sheets, Yumu Laser has a laser cutting machine suitable for cutting acrylic plates, because the plate is cut by a special cutting machine, in order to give full play to the maximum efficiency of the cutting machine!

The fiber laser cutting machine does not produce light for the following reasons:

1. Check whether the power supply of the fiber laser cutting machine is in good contact to ensure that the power supply is in good contact 2. Check whether the circulating waterway of the fiber laser gas cutting machine chiller is blocked, and the waterway should be kept unobstructed. The special dual-temperature chiller is specially designed for fiber lasers and has triple filtration; There are two refrigerations, one for the laser and the other for the lenses.

Hello answer, my side is inquiring for you, please wait a while, my side will reply to you 1Whether the laser power switch (green switch) of the machine is on or not2Check whether the chiller is turned on, and check whether the light signal, control signal, and water protection signal of the chiller are normal.

3.Check whether the light from the laser tube is normal; Low light (purple) is abnormal, normal is pink, whether the water flow of the laser tube is normal.

4.Check whether the laser optical path of the machine is normal, press the light to see if the laser tube is bright, bright and the laser head is not bright, then there is a problem with the optical path.

Radium laser will answer for you:

1.Check whether the water tank of the fiber laser cutting machine is alarmed.

a.Alarm, connect the water inlet and outlet behind the water tank with a water pipe, and the water tank is energized to see if it is alarmed. If you call the police, the tank is broken.

If it is not alarmed, it is that the waterway of the fiber laser cutting machine is not smooth, check whether the water pipe is bent or pressed by something, and whether there is any debris in the water tank (replace the pure water in the water tank).

b.If you don't give the alarm, check whether the power supply fan of the fiber laser cutting machine is rotating. The power supply of the fiber laser cutting machine is turned by the fan, and the laser power supply is shorted with the wire.

2.Whether the fiber laser cutting machine produces light.

a.If the light is out, the wire on the motion control card is loose, or the motion control card is broken (replace the board).

b.There is no light, and the laser power supply is broken. (In rare cases, the fiber laser cutting machine is broken) (Check whether there is ignition at the high-voltage end of the fiber laser cutting machine, and the ignition is easy to burn the laser power supply and the electronic components of the board).

The power supply fan of the fiber laser cutting machine does not rotate, and the 220v port of the laser power supply is tested with a pen, whether there is electricity. There is electricity, and the laser power supply is bad. (repair or replacement of power supply); If there is no power, check the power switch and line of the fiber laser cutting machine.

If it can't be solved, you can contact the manufacturer and fix it in time.

When using a fiber laser cutting machine, there will occasionally be no light. When such a situation occurs, first of all, we should not panic, we must calm down to check the whole laser cutting machine, troubleshooting, Bond laser for you to analyze several places that need to be troubleshooting.

1.Check the focal length of the laser cutting machine, whether there is any shift or change, then check whether the focusing lens is clean and clean, strictly check whether the optical path is offset, and carefully adjust the optical path.

2.Check the mirrors for contamination or damage, and clean or replace the mirrors.

3. Check whether the cooling water is circulating normally, and secondly, check whether the water quality or water temperature of the cooling water is normal.

4.Check whether the laser power supply is powered on, if not, it is necessary to consider whether the laser power supply is damaged and replace the power supply.

5.Check whether the laser tube is damaged or aged.
