플레이트 콤팩트 고반복률 나노초 레이저 절단 의 버가 발생하는 이유

 

레이저 판금 절단은 이미 일반적입니다. 높은 작업 효율과 완제품 절단의 높은 품질로 인해 판금 가공 스테이션의 표준 장비가 되었습니다. 그러나 일부 고객이 레이저 절단기를 사용하면 가공물이 많은 Burr로 절단됩니다. 많은 사람들이 레이저 절단기의 품질 문제라고 생각하지만 그렇지 않습니다.

판금 가공 과정에서 레이저 절단기의 가스 순도 및 매개 변수 설정은 가공 품질에 영향을 미칩니다. 장비 + 가스 + 매개변수가 최상으로 조정되면 절단된 공작물에 버가 없습니다.

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.
