在便携式数控切割机在开展激光切割工作中的那时候，倘若有仔细观查过，坚信大伙儿也可以或多或少的看得出，手持式激光切割机的激光切割速度效果之间有着深切的联系，所以大家以后再使用便携式数控切割机的时候，不要认为切割速度与切割效果之间并没有什么相关性。

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.

在金属加工中，许多金属材料，不管它是什么样的硬度，都可以使用便携式数控切割机进行切割。便携式数控切割机激光切割过程中添加与被切材料相适合的辅助汽体。钢切割时利用氧作为辅助汽体与熔融金属产生放热化学反应氧化材料，同时帮助吹走割缝内的熔渣。切割聚丙烯一类塑料使用压缩空气，棉、纸等易燃材料切割使用惰性汽体。进入喷嘴的辅助汽体还能冷却聚焦透镜，防止烟尘进入透镜座内污染镜片并导致镜片过热。

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.

数控机床手持式激光切割机在激光切割时激光切割速率的挑选我觉得也很关键，激光切割速率范畴可依照机器设备表明选中或用实验来明确，因为原材料的薄厚度，材料不一样，溶点高矮，导热系数尺寸及其熔融后的界面张力等要素，激光切割速率也相对的变

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
