激光切割以其、切割速度高、切缝窄、切割质量好、热影响区小、加工柔性大等优点在现代工业中得到广泛的应用,同时它也是激光加工技术中最为成熟的技术之一。随着科技发展,现在激光切割都是通过与数控技术、计算机辅助设计与辅助制造(CAD/CAM)软件相结合,通过预先在计算机内设计,可进行众多复杂零件的整张板料套排切割,既节省材料,也可实现多零件同时切割以及全自动化操作,甚至可实现三维空间曲线的激光自动切割。
1.切割速度
其实不管是什么样的材料,能够使切割的速度和材料极度吻合,那么这个时候的切割效果就是最好的,过快或是过慢都会对激光切割有所影响。
2.材料的厚度和粗糙程度
激光切割最适合切割薄板,效果最好的厚度是12mm以下的碳钢和6mm以下的不锈钢,加工出来的质量明显增强,效率上也出现了保障。如果说切割<1mm材料,切口也会极为光滑的。材料表面粗糙度,材料表面粗糙度也决定着切割质量的好坏,一般越光滑的材料,切割出来的质量也就越好。
3.辅助气体压力和种类
压力越高的辅助气体,气体的纯度就高,材料粘附的杂质就会很少,切割口越来越光滑。一般来说,氧气切割的速度是最快的,氮气的切割效果最好,成本也低。不同的气体,切割的效果也会有所差距。
4.激光设备的工作功率和模式
经过研究证明了,激光设备的功率越高,即使是切割同样的板材,效果也会比一般的要好。
激光切割的模式和材料是有一定的契合度,越高效果越好。文章来源:(http://www.akstzs.cn )
5.焦点位置
激光切割机的焦点能对上,切割的精度和准确度才能达到想要的要求。
Laser cutting, cutting speed, cutting slit, good cutting quality, small heat affected zone, processing flexible advantages in modern industry are widely used. At the same time, it is the laser processing technology most one of mature technology. With the development of science and technology now laser cutting is combined with numerical control technology, computer aided design and computer aided manufacture (CAD / CAM) software, through the advance in computer design, many complex parts of the whole plate nesting row of cutting, saving materials, also can realize multi parts and cutting, and automatic operation, or even a three-dimensional space curve automatic laser cutting.
1 cutting speed
Actually no matter what kind of material, can make the cutting speed and material is extremely consistent, then the cutting effect is the best, too fast or is too slow will of laser cutting effect.
2 thickness and roughness of material
Laser cutting is the most suitable for cutting thin plate, the effect of the best thickness is below 12mm carbon steel and 6mm of the following stainless steel, the quality of the processing is obviously enhanced, the efficiency also appeared the guarantee. If you cut <1mm material, the cut will be extremely smooth. Material surface roughness, material surface roughness also determines the quality of the cut, the general smoother material, cutting out the quality is better.
3 auxiliary gas pressure and type
The higher the pressure, the higher the purity of the gas, the impurities in the material will be less, and the cutting mouth is more and more smooth.. In general, the speed of oxygen cutting is the fastest, the cutting effect of nitrogen is the best, the cost is also low. Different gases, the effect of cutting will also be a gap.
4 working power and mode of laser equipment
After research, the power of laser equipment is higher, even cutting the same board, the effect will be better than the general. Laser cutting of the mode and material is a certain degree of fit, the higher the better.
5 focus position
The focus of laser cutting machine can be on the accuracy and accuracy of the cutting can achieve the desired requirements.
