How does laser cutting machine technology deal with burrs?

Superwave Laser Technology Co.,Ltd | Updated: Jun 09, 2018


Laser cutting machine technology is how to deal with the burr problem, some customers in the use of processing sheet metal laser cutting machine, cutting out the artifacts that effect is very not ideal, and the burr is very much, and many customers begin to doubt the quality problem of the laser cutting machine products, actually otherwise. In the cutting process of metal laser cutting machine, because of improper operation and technical problems, the materials it processes will produce burrs. Burrs can only be produced in metal cutting, there is no burr problem in non-metal cutting. How did the burrs come about? A burr is an excess of particles of residue on the surface of a metal material. If a material has a burr, the material can be qualitatively inferior. The more burrs, the lower the quality. What are the causes of the burrs in sheet metal processing by laser cutting machine? Let's give you a brief analysis.



Based on the working principle of laser cutting machine, the causes and solutions of the burrs are obtained.
First, the upper and lower position of the focal point of the beam deviates.
Solution: adjust the focus position according to the offset position.
2. The output power of the machine is insufficient.
Solution: check the laser cutting machine is working properly. If it is abnormal, it needs to be repaired and maintained in time. If normal, check to see if the output value is correct.
3. The wire cutting speed of the cutting machine is too slow.
Solution: adjust and improve wire cutting speed in time.
4. The purity of auxiliary gas of the cutting machine is insufficient.
Solution: explain to increase the purity of the auxiliary gas.
5. The laser beam of the cutting machine is offset by the point of the laser beam.
Solution: focus on the debugging, timely adjustment
The instability caused by the laser cutting machine running for too long.
Solution: turn off the machine and restart it and let it rest.
Metal laser cutting machine is a sophisticated machine, the operation is a delicate work, often a data error will cause its work is not normal, so in the work to strict careful, reduce and avoid mistakes.
The main reason of the burr in the processing sheet metal of laser cutting machine; When the laser cutting machine is working on the workpiece, the high energy produced by laser beam irradiation on the workpiece surface causes the workpiece surface to vaporize rapidly and evaporate to achieve the purpose of cutting. But there's a core device that we have to pay attention to, which is the auxiliary gas. The auxiliary gas is that when the workpiece's irradiation surface is vaporized, the slag on the workpiece surface is blown off. If the auxiliary gas is not used, the slag will cool down and form a burr attached to the cutting surface. This is the main cause of burrs.
Another reason is the quality problem of the equipment itself, and also the parameter setting factor, so when customers buy laser cutting machine, it is necessary for professional operators to adjust the equipment.
Laser cutting machine processing sheet metal burr solution;
1. Be sure to equip air compressor and use auxiliary gas for cutting.
2. Find a professional operator to adjust the parameters of laser cutting machine until normal.
