生锈铁板可以直接用激光切割机切割吗?

来源:www.4066.com 时间:2020-02-28 

在炎热潮湿的南方,铁板和碳钢等金属材料生锈是一种非常正常的现象。生锈的钢板,你能用激光切割机直接切割吗?答案当然是:不。
In the hot and humid South, rust of metal materials such as iron plate and carbon steel is a very normal phenomenon. Can you cut the rusty steel plate directly with a laser cutter? The answer, of course, is: No.
我们都知道激光切割机是一种粘土制品,但激光切割机的激光对锈蚀表面是无能为力的。因为激光本身不能成为光源,只有通过薄板工件的表面吸收才会产生热量。对于未生锈的材料和生锈的材料,激光吸收是非常不同的,切割效果也不同。
We all know that laser cutting machine is a kind of clay product, but the laser of laser cutting machine can't do anything to rusty surface. Because the laser itself can not be a light source, only through the absorption of the surface of the thin plate workpiece can heat be generated. For rust free materials and rusty materials, laser absorption is very different, and the cutting effect is also different.

以5mm以下的生锈片为例,整个均匀锈蚀板的切削条件优于不均匀锈蚀板。由于整个均匀锈蚀板吸收激光器也是均匀的,可以进行良好的切削。对于表面锈蚀不均匀的材料,在切削前材料的表面条件应该是均匀的。当然,如果条件允许,建议先用磨床去除锈蚀。
For example, the cutting condition of the uniform corrosion plate is better than that of the uneven corrosion plate. Because the absorption laser of uniform corrosion plate is also uniform, it can be cut well. For the material with uneven surface corrosion, the surface condition of the material should be uniform before cutting. Of course, if conditions permit, it is recommended to use a grinder to remove rust first.
对于生锈较厚的板材,如果直接用激光切割机切割生锈板材,很容易造成防渗切割现象,切割质量不佳,甚至出现溅渣现象,可能会导致保护镜片,甚至聚焦镜片破损,导致陶瓷体爆裂。因此,如果切割生锈较厚的材料,必须先除锈后切割。
For thick rusted plates, if the rusted plates are directly cut by laser cutting machine, it is easy to cause the phenomenon of anti-seepage cutting, poor cutting quality, and even slag splashing, which may lead to the damage of protective lenses, even focus lenses, resulting in the bursting of ceramic body. Therefore, if cutting the material with thick rust, the rust must be removed before cutting.
