How to handle the burr of laser cutting ?

How the Laser cutting technology deal with the burr problem, some customers in the use of laser cutting machine processing of sheet metal workpiece, the effect of cutting out workpiece is not ideal, and there are many burrs,and then many customers began to suspect the quality problems of products cutted by the laser cutting machine . In fact ,during the cutting process of metal laser cutting machine, because improper operation and technical problems cause processing materials to produce the burr.

The burr is only produced in metal cutting. There is no burr problem in non-metal cutting.How did the burr come from?In fact, the burr is the excess residue particles of metal materials.If a material has a burr, then the material can be qualitatively inferior. The more burrs, the lower the quality.

Metal laser cutting machine is a precision machine. Operation is also a fine work. Often a data error will cause its work to run erroneous, so we must be careful and meticulous in work, reduce and avoid mistakes.

The main reason of sheet metal burrs for the laser cutting machine processing ; The high energy produced by the laser beam on the surface of the workpiece causes the workpiece surface to vaporize rapidly, and evaporation, to achieve the purpose of cutting device. But there is a core device, we must pay attention to, is the auxiliary gas. The gas is to blow off surface slag when the irradiation surface after gasification, without the use of auxiliary gas, slag will form a burr attached to the cutting surface after cooling. This is the main reason for the formation of burr. Another reason is that the quality problems of the equipment itself, then there is the parameter setting factor, So when customers after buying laser cutting machines, it is necessary to have the professional operator debug the equipment.


The working principle of the laser cutting machine and the technical analysis obtained the cause and solution of the burr.

First, there is a deviation between the upper and lower positions of the focus of the beam. The solution is to adjust the position of the focus and adjust it according to the position of the offset.

Second, the output power of the machine is not enough. The solution is to check whether the laser cutting machine works normally. If it is abnormal, it needs timely repair and maintenance. If normal, check whether the output value is correct.

Third, the cutting speed of cutting machine is too slow. The solution is to adjust and improve the speed of wire cutting in time.

Fourth, the purity of the auxiliary gas of the cutting machine is not enough. The solution is to improve the purity of the auxiliary gas.

Fifth, The laser beam of the cutter has been offset. Solution: focus on debugging, timely adjustment.
Sixth, the unstable operation time of the laser cutting machine is too long. Solution: turn off the machine and let the machine rest.
