1.首先檢查激光輸出是否有問題，打的光斑是不是很圓(圓的說明激光能量的橫向分布是均勻的,切割質量才好)

2.檢查激光傳輸過程中的鏡片是否有臟，或者是否透鏡有臟,透鏡是否有肉眼不易發現的細小裂痕，這些都會影響激光的傳輸。

3.之后是工藝參數方面的調整。如果是不銹鋼激光切割后產生的毛刺是有一定硬度的，很難去除，非常耗時，還影響美觀。最好是從根源上解決。

首先輔助氣體的純度要高，可以換一家質量好一點的氣體供應商。氣體的純度很關鍵。

激光切割如何減少毛刺的出現？

再就是把切割參數調到最佳，焦距、切割速度、功率、運行時間等等，要經過多次調整（請務必讓專業的工程師調試），靠機器提供的參數是割不出精美的工件的，所以只有經過多次嘗試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.
