Las razones de las rebabas de la placa de corte por láser compacto de nanosegundos de alta tasa de repetición

El corte de chapa por láser ya es común. Debido a su alta eficiencia de trabajo y alta calidad de corte del producto terminado, se ha convertido en el equipo estándar de las estaciones de procesamiento de chapa. Sin embargo, cuando algunos clientes utilizan la máquina de corte por láser, las piezas de trabajo se cortan con muchas rebabas. Mucha gente piensa que es un problema de calidad de la máquina de corte por láser, pero no es así.

En el proceso de procesamiento de láminas de metal, la pureza del gas y la configuración de los parámetros de la máquina de corte por láser afectarán la calidad del procesamiento. Si los parámetros del equipo + gas + se ajustan de la mejor manera, la pieza de trabajo cortada estará libre de rebabas.

¿Cómo ocurren los fallos?

In fact, burrs are excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the surface of the workpiece vaporizes and evaporates the surface of the workpiece to achieve the purpose of cutting. But here is a device that we must pay attention to, which is gas.

The gas is to blow off the molten slag on the surface of the workpiece when the irradiated surface of the workpiece is vaporized. If no gas is used, after the molten slag is cooled, it will form burrs attached to the cutting surface. Therefore, the purity of the gas should be high. You can switch to a higher-quality gas supplier. The purity of the gas is very important. Do not use cylinder gas, because after two fillings, the purity is not good and the gas is wasted.

Another reason is the quality of the equipment itself, as well as the parameter setting factor. Therefore, after the customer purchases the laser cutting machine, it is necessary to have an experienced operator debug the equipment. Therefore, the cutting parameters should be adjusted as best as possible. The air pressure, flow, focal length and cutting speed must be adjusted many times. The parameters provided by the machine cannot be used to cut high-quality workpieces.

If a piece of material has burrs, it can be qualitatively defective. The more burrs, the lower the quality.

Generally speaking, when the laser cutting machine has burrs, it can be checked and solved from the following aspects:

1. The output power of the laser cutting machine is not enough.

Solution: Check whether the laser cutting machine is working properly. If it is abnormal, it needs to be repaired and maintained in time. If it is normal, check whether the output value is correct.

2. The up and down position of the focus of the beam is deviated.

Solution: Adjust the position of the focus and adjust it according to the offset position it produces.

3. The purity of the gas of the cutting machine is not enough.

Solution: Change the gas.
