1.首先检查激光输出是否有问题，打的光斑是不是很圆(圆的说明激光能量的横向分布是均匀的,切割质量才好)

2.检查激光传输过程中的镜片是否有脏，或者是否透镜有脏,透镜是否有肉眼不易发现的细小裂痕，这些都会影响激光的传输。

3.之后是工艺参数方面的调整。如果是不锈钢激光切割后产生的毛刺是有一定硬度的，很难去除，非常耗时，还影响美观。最好是从根源上解决。

首先辅助气体的纯度要高，可以换一家质量好一点的气体供应商。气体的纯度很关键。

激光切割如何减少毛刺的出现？

再就是把切割参数调到最佳，焦距、切割速度、功率、运行时间等等，要经过多次调整（请务必让专业的工程师调试），靠机器提供的参数是割不出精美的工件的，所以只有经过多次尝试才能把毛刺降到最低。

1. First check whether there is a problem with the laser output and whether the light spot is round(the circle indicates that the lateral distribution of laser energy is uniform and the cutting quality is good)
2. Check whether the lenses in the laser transmission process are dirty, or whether the lens is dirty, and whether the lens has small cracks that are not easily visible to the naked eye, these will affect the transmission of the laser.
3. The following is the adjustment of process parameters. If it is stainless steel laser cutting after the burr is a certain hardness, difficult to remove, very time consuming, but also affect the aesthetic. It's best to address the root causes.
First of all, the purity of the auxiliary gas should be high, you can replace a better quality gas supplier. The purity of the gas is crucial.
How can laser cutting reduce the appearance of burrs?
The other is to set the cutting parameters to the best, focal length, cutting speed, power, running time, etc.. After many adjustments(please make sure that professional engineers debug), the parameters provided by the machine can not cut out exquisite workpieces. So only after many attempts can the burr be minimized.
