那么激光切割机与其他切割机相比较它的优势在哪里呢
 

与其他热切割方法相比,热切割过程与其它方法一样,不能像激光束作用在一个很小的区域上,导致切口宽、热影响区大、工件变形明显。激光切割机切割金属和非金属。

那么激光切割机与其他切割机相比较它的优势在哪里呢

氧燃料(如乙炔)切割。这种方法主要用于切割低碳钢。由于其巨大的热输入和较低的切削速度,它很少用于加工材料在6mm以下的精确尺寸。等离子切割。切割速度明显快于氧乙炔切割,但切割质量差。刀刃顶端为圆头,刀刃明显呈波浪状,防止电弧产生的紫外线辐射。它比激光切割机稍好一些,因为它适用于切割较厚的钢板和高反射率的铝合金。


模具冲裁。大量的冲压零件的冲压方法,成本低,生产周期短。但其对设计变更的适应性很差,新模具需要长时间的设计,成本高,适合中小型生产,激光切割的特性将得到充分展示。此外,激光编程切割有利于工件的紧密排列和节省材料,而模具冲压要求材料保留在每个工件周围。

复杂零件的分段冲孔。在一般情况下,工件比模具冲头经常枢纽规模大得多,有些复杂,导致切削刃是许多小贝壳状的边缘,二初步加工改造。此外,冲头形成一个比激光切割机更广泛的切口,产生大量的铁屑。锯。切削薄金属时,其速度比激光切割速度慢得多,而激光作为一种灵活的非接触式仿形刀具,从材料的任何一个点切割,任意切割。这一点,锯切很难做到。


电火花加工。一般来说,利用电蚀或熔化的电火花加工和电解加工两种方法对硬质材料进行精细加工,切口的粗糙度比较好,但切割速度比激光切割机的速度高出几个数量级。水切割。许多金属可以被削减,但成本高。



Compared with other thermal cutting methods, the same way as the thermal cutting process, other methods can not act as a laser beam acting on a very small area, resulting in wide incision, large heat affected zone and obvious deformation of the workpiece. The laser cutting machine cuts metal and nonmetal.


Oxygen fuel (such as acetylene) cutting. This method is mainly used for cutting low carbon steel. Because of its great heat input and low cutting speed, it is rarely used to cut materials with exact sizes under 6mm. Plasma cutting. The cutting speed is obviously faster than oxyacetylene cutting, but the cutting quality is poor. The top of the cutting edge is round headed, the cutting edge is obviously wavy, and the ultraviolet radiation produced by the arc is also prevented. It is slightly better than the laser cutting machine, because it is suitable for cutting the thicker steel plate and the aluminum alloy with high reflectivity to the beam.


Die blanking. A large number of parts die punching method, low cost, short production cycle. But its adaptability to the design changes is very poor, the new mold needs a long time design, high cost, for medium and small-scale production, the characteristics of laser cutting will be fully displayed. In addition, the laser programmed cutting facilitates the close arrangement of the workpiece and saves material, while the die stamping requires the material to be reserved around each workpiece.


Segment punching of complex parts. In general, the workpiece is much larger than the size of the die punch often hub, some parts are complex, which leads to the cutting edge is many small conchoidal edge, second preliminary processing renovation. In addition, the punches form a much wider incision than the laser cutting machine, producing a large amount of iron filings. Sawing. Cutting thin metal, its speed is significantly slower than laser cutting, and laser as a flexible non-contact, profiling cutting tool, cutting from any point of the material, cutting it in any direction. This point, sawing is difficult to do.


Edm. In general, use electric corrosion or melting effect of EDM and ECM two methods used for fine processing of hard material, the roughness of the incision is better, but the cutting speed is higher than that of laser cutting machine speed several orders of magnitude. Water cutting. Many metals can be cut, but the cost is high.
