How Do Laser Cutting Machines Deal With Burrs?


Jan 12.2018
The problem of how to deal with the burr by laser cutting machine is puzzled. How does the burr come into being? What is the cause of the burr in the laser cutting machine? Let's give you a simple analysis.
Laser cutting technology is how to deal with the burr problem, some customers in the use of laser cutting machine processing of sheet metal workpiece, cutting out the effect is not ideal, but the burr is very much, the quality problem and many customers began to suspect that the laser cutting machine products, in fact. In the cutting process of metal laser cutting machine, because of improper operation and technical problems, the material in its processing will not produce burr. Burr is only produced in metal cutting, and there is no burr in non-metal cutting. How does the burr come into being? In fact, the burr is too much residue on the surface of a metal material. If a piece of material has burr, the material can be qualitatively inferior, the more the burr, the lower the quality. What is the cause of the burr in the laser cutting machine? Let's give you a simple analysis.



The principle of the laser cutting machine, the technical analysis of the causes of its burr and solution.
First, there is a deviation in the upper and lower positions of the focus of the beam.
The solution: adjust the position of the focus, and adjust it according to the position of the offset.

Two, the output power of the machine is not enough.
Solution: check the work of the laser cutting machine is normal. It is not normal to repair and maintain in time. If normal, check whether the output value is correct.

Three, the cutting speed of the cutting machine is too slow.
Solution: adjust and improve the speed of wire cutting in time.

Four. The purity of the auxiliary gas of the cutting machine is not enough.
The solution is to explain the improvement of the purity of the auxiliary gas.

Five, the increase of the laser beam of the cutting machine has been offset.
Solution: focus on the debugging, timely adjustment

Six, the laser cutting machine operation time is too long and the instability.
The solution: turn off the machine and reboot the machine.

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.

Laser cutting machine is the main reason for burr of sheet metal. When laser cutting machine processes workpiece, laser beam irradiates the high energy generated on the workpiece surface, which makes the surface of the workpiece vaporized quickly and evaporates to achieve the purpose of cutting. But there is a core device that we have to pay attention to, that is, the auxiliary gas. The auxiliary gas is when the workpiece surface irradiation after gasification, blew the slag on the surface of workpiece, without the use of auxiliary gas, slag after cooling, will form a burr attached to the cutting plane. This is the main reason for the formation of burrs.

Another reason is the quality problem of the equipment itself, as well as the parameter setting factors. All customers must have professional operators debugging the equipment after buying the laser cutting machine.
The solution of the burr in the laser cutting machine to process the sheet metal.
1. must be equipped with air compressor, the use of auxiliary gas to cut.
2. find the professional operator to debug the parameters of the laser cutting machine until it is normal.
