How To Solve Burning In Metal Fiber Laser Cutting Machine-Anne

How To Solve Burning In Metal Fiber Laser Cutting Machine

The fiber  laser cutting process produces a lot of heat when the sheet metal part is processing, the heat is not diffused in time, and the burning edge phenomenon is caused.In the machining of metal fiber laser cutting machine, the outside of the hole can be cooled, but the part of the small hole inside the single hole has less heat diffusible space, and the heat is too concentrated to cause over burning, slagging and so on.In addition, in the thick plate cutting, the molten metal accumulated on the material surface and the heat accumulation during the perforation will make the auxiliary airflow disordered, and the heat input will be excessive, which will lead the burning of the edge.

So how to solve the problem of burning and slagging?

Solution of over burning during fiber laser cutting of small hole in carbon steel:

In the carbon steel cutting with oxygen as the auxiliary gas, the key to solve the problem is how to suppress the generation of oxidation reaction heat. It is cut by auxiliary oxygen during perforation and lagg switch to auxiliary air or nitrogen.

The pulse cutting condition with low frequency and high peak output power can reduce the heat output and optimize the cutting condition.

Setting the condition as a single pulse laser beam, the high peak output of high energy intensity and the low frequency condition can reduce the accumulation of molten metal on the surface of the material during the perforation process and reduce the heat output.

The solution of Laser cutting of aluminum alloy and stainless steel:

In the processing of such materials, the auxiliary gas used is nitrogen, which does not burn during cutting. However, because of the high temperature of the material inside the pore, the phenomenon of slagging on the inside will be more frequent.

The solution to this problem is to increase the pressure of the auxiliary gas and to set the condition as the pulse condition of high peak output and low frequency.

When the auxiliary gas use air, it will not overburn, but it is easy to appear slags at the bottom. It is necessary to set the conditions as high auxiliary gas pressure, high peak output, low frequency pulse condition.

How to operate fiber laser metal cutting machine – Jennifer

Fiber laser cutting machine has now become an indispensable modern sheet metal industry processing equipment, with the upgrading of the industry, the processing requirements of the upgrade, not only in the efficiency of a very high upgrade in the optimization of the operation is to do the ultimate , The following to tell you about the specific operation process.

Fiber laser cutting machine operation steps:

1. Determine the need to process the material, the sheet metal material fixed flat on the machine, and then determine the stability of the material placed in order to avoid jitter in the cutting process, resulting in cutting accuracy can not meet the requirements.
In the case of
2. Operate the console, enter the product cutting pattern, and cut the material thickness and other parameters, and then adjust the cutting head to the appropriate focus position, and then reflect and adjust the nozzle center.
In the case of
3. Start the regulator and the chiller, set the water temperature of the chiller and the water pressure.
In the case of
4. Start the laser and then turn on the machine.

Although the above four points are very short, but in the actual operation of the process have to spend a lot of time to practice, to familiar with each operation details. It is inevitable in the operation of fiber laser cutting machine, there will be some problems and problems, the following also to share with you.

Familiar problems happened in fiber laser metal cutting machine:

1. Boot without any reflection
Is the power fuse burned: Replace the fuse.
Power input is normal: Check the power input and make it normal.
The main power switch is damaged: replace the total power switch.

2. No laser output or laser is weak
Light path is offset: carefully adjust the optical path.
Whether the focus of the device is changed: Adjust the focus.
Whether the laser tube is damaged or aging: Replace the laser tube.
Whether the laser power is energized: Check the laser power supply circuit to make it normal.
Laser power is damaged: replace the laser power.

3. The processing size has errors or errors
Is the signal line normal: replace the signal line.
Power supply is unstable or interference signal: install the regulator or remove the interference signal.

Whether the processing parameters are set correctly (such as layout, etc.): reset the corresponding parameters.
Processing program is normal: check the preparation of the processing procedures, modify until it is normal.
