The program compiled by the optical fiber laser cutting machine no longer needs manual correction, but is a three-dimensional processing program which is completely consistent with the theoretical cutting edge line and can be directly used for cutting products. The laser cutter will focus the laser beam emitted from the laser through the optical system into a high power density laser beam. The laser beam irradiates the surface of the workpiece, so that the workpiece reaches the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will blow away the melted or gasified metal. It can ensure that the cutting process is always consistent with the actual cutting edge state, and there is no two-dimensional line that can not be drawn. The whole cutting process does not need manual intervention, from the source to ensure that each product processing is consistent with the digital model, so that the original need to explore many times before the cutting edge can only be completed 3 to 4 times.

　　用光纤激光切割机加工金属时，线切割精度高，能切割厚板，但其缺点是速度慢。光纤激光切割机利用光纤激光发生器作为光源的激光切割机。光纤激光器是上新发展的一种新型光纤激光器输出高能量密度的激光束，并聚集在工件表面上，使工件上被超细焦点光斑照射的区域瞬间熔化和气化，通过数控机械系统移动光斑照射位置而实现自动切割。有时其他的方法需要穿孔和穿孔来切割，而且切割的尺寸也是非常有限的。激光切割可以冲切材料。切削速度快，加工尺寸范围比线切割大得多。激光切割目前广泛应用于金属加工行业，激光切割速度快，精度高。中薄板、铝板、不锈钢等金属板材的切割具有优势，这就是光纤激光切割机不可替代的原因，相信随着人们对激光切割产品需求的不断增加，光纤激光切割的机会也越来越多。

　　When metal is machined by optical fiber laser cutting machine, WEDM has high precision and can cut thick plates, but its disadvantage is slow speed. Fiber laser cutting machine uses fiber laser generator as light source. Fiber laser is a new type of fiber laser developed in the world. It produces high energy density laser beams and gathers on the surface of the workpiece, which instantly melts and gasifies the area illuminated by the ultra-fine focus spot, and realizes automatic cutting by moving the spot illumination position through the numerical control mechanical system. Sometimes other methods need perforation and perforation to cut, and the size of cutting is very limited. Laser cutting can cut materials. The cutting speed is fast and the processing size range is much larger than that of wire cutting. Laser cutting is widely used in metal processing industry. Laser cutting is fast and accurate. The cutting of sheet metal, such as medium and thin plate, aluminium plate and stainless steel has absolute advantages, which is the reason why the optical fiber laser cutting machine can not be replaced. I believe that with the increasing demand for laser cutting products, the opportunities of optical fiber laser cutting are also increasing.

　　光纤激光切割机与其他切割方法有许多不同之处。光纤激光切割机利用光纤激光发生器作为光源的激光切割机。光纤激光器是上新发展的一种新型光纤激光器输出高能量密度的激光束，并聚集在工件表面上，使工件上被超细焦点光斑照射的区域瞬间熔化和气化，通过数控机械系统移动光斑照射位置而实现自动切割。对于某些金属零件的切削加工，可以采用冲裁剪切工艺，效率高，速度快。而且成本也很低，但需要特定的模具和刀具才能进行切割，只能在薄的板材上进行冲切，而光纤激光切割机的激光切割与切割方法相比具有更好的灵活性，任何形状的工件都可以在任何时候进行切割，而不需要模具上的点。

　　There are many differences between optical fiber laser cutting machine and other cutting methods. Fiber laser cutting machine uses fiber laser generator as light source. Fiber laser is a new type of fiber laser developed in the world. It produces high energy density laser beams and gathers on the surface of the workpiece, which instantly melts and gasifies the area illuminated by the ultra-fine focus spot, and realizes automatic cutting by moving the spot illumination position through the numerical control mechanical system. For the cutting of some metal parts, the punching and shearing process can be adopted, which has high efficiency and high speed. And the cost is also very low, but it requires specific dies and tools to cut, can only be punched on the thinnest sheet, and the laser cutting of optical fiber laser cutting machine is more flexible than the cutting method, any shape of the workpiece can be cut at any time, without the need for points on the die.

　　冲切工艺难以或不可能实现，因此并没有得到广泛的应用。火焰切割也是金属领域中常用的切割工艺之一。切割的厚度范围也很大，但与激光切割相比，切割表面的质量和精度相对较差，但厚板和加工的范围要大于激光切割的范围。因此，光纤激光切割机一般是用来切割较精细的。

　　Punching process is difficult or impossible to achieve, so it has not been widely used. Flame cutting is also one of the common cutting processes in metal field. The thickness range of cutting is also large, but compared with laser cutting, the quality and precision of cutting surface are relatively poor, but the thickness and processing range of thick plate are larger than laser cutting range. Therefore, optical fiber laser cutting machine is generally used to cut more fine.
