在便攜式數控切割機在開展激光切割工作中的那時候，倘若有仔細觀查過，堅信大伙兒也可以或多或少的看得出，手持式激光切割機的激光切割速度效果之間有著深切的聯系，所以大家以后再使用便攜式數控切割機的時候，不要認為切割速度與切割效果之間并沒有什么相關性。

At that time when the portable CNC cutting machine was carrying out laser cutting work, if you have looked carefully, you firmly believe that we can see more or less that there is a deep connection between the laser cutting speed effect of the handheld laser cutting machine, so when you use the portable CNC cutting machine in the future, do not think that there is no relationship between the cutting speed and the cutting effect. What relevance.

在金屬加工中，許多金屬材料，不管它是什么樣的硬度，都可以使用便攜式數控切割機進行切割。便攜式數控切割機激光切割過程中添加與被切材料相適合的輔助汽體。鋼切割時利用氧作為輔助汽體與熔融金屬產生放熱化學反應氧化材料，同時幫助吹走割縫內的熔渣。切割聚丙烯一類塑料使用壓縮空氣，棉、紙等易燃材料切割使用惰性汽體。進入噴嘴的輔助汽體還能冷卻聚焦透鏡，防止煙塵進入透鏡座內污染鏡片并導致鏡片過熱。

In metal processing, many metal materials, no matter what kind of hardness it is, can be cut by portable CNC cutting machine. In the laser cutting process of the portable numerical control cutting machine, the auxiliary steam body suitable for the material to be cut is added. During steel cutting, oxygen is used as the auxiliary material to generate exothermic chemical reaction oxidation between steam and molten metal, and at the same time, it helps blow away the slag in the slit. For cutting polypropylene, compressed air is used, and inert gas is used for cutting cotton, paper and other flammable materials. The auxiliary vapor entering the nozzle can also cool the focus lens, prevent smoke from entering the lens base to pollute the lens and cause the lens to overheat.

數控機床手持式激光切割機在激光切割時激光切割速率的挑選我覺得也很關鍵，**激光切割速率范疇可依照機器設備表明選中或用實驗來明確，因為原材料的薄厚度，材料不一樣，溶點高矮，導熱系數尺寸及其熔融后的界面張力等要素，激光切割速率也相對的變

In my opinion, the selection of laser cutting rate of CNC machine tool hand-held laser cutting machine is also very important. The best range of laser cutting rate can be determined according to the selection of machine and equipment or by experiments. Because of the thin thickness of raw materials, different materials, high and low melting point, thermal conductivity size and interface tension after melting, the laser cutting rate also changes relatively.http://www.jnzrtcsk.com
