Fiber laser cutting machine is already common in sheet metal processing. Due to their high processing efficiency and high cutting quality of finished products, they have become standard equipment for sheet metal processing stations. However, some customers have many burrs on the workpieces cut when using laser cutting machines. Many people think that it is a quality problem of the fiber laser cutting machine products, but it is not. Now let me explain to you the causes and solutions for burrs on fiber laser cutting machines!

Several reasons for burrs in cutting:

1. The purity of the auxiliary gas of the fiber laser cutting machine does not meet the required standards, which will also cause burrs on the workpiece.

2. The cutting line speed of the fiber laser cutting machine is too slow, which destroys the surface quality of the cutting surface and produces burrs.

3. The output power of the fiber laser cutting machine is not enough, and the metal cannot be effectively vaporized, resulting in excessive slag and burrs.

4. The fiber laser cutting machine has been working for too long, causing the equipment to be in an unstable working state, which will also cause burrs.

5. The upper and lower positions of the laser beam focus generated by the fiber laser cutting machine deviate, resulting in the energy not being gathered exactly on the workpiece, the workpiece is not fully vaporized, the amount of slag generated increases, it is not easy to blow off, and it is easier to produce burrs.

Several ways to solve burrs:

1. Replace the auxiliary gas with higher purity.

2. Adjust and increase the cutting line speed in time to reach the normal value.

3. Adjust the position of the laser beam focus to the best state according to the offset position it produces.

4. Turn off the fiber laser cutting machine, restart it after a period of time, and let it get enough rest.

5. Check whether the fiber laser cutting machine is working normally. If it is not normal, it needs to be repaired and maintained in time; if it is normal, check whether the output value is correct.

In fact, burrs are excessive residue particles on the surface of metal materials. When the fiber laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the workpiece surface vaporizes and evaporates the workpiece surface to achieve the purpose of cutting. If a material has burrs, then the material can be qualified as a defective product. The more burrs, the lower the quality. Therefore, we must pay more attention in the future processing!
