Three Focus Relations of Zhucheng Fiber Laser Cutting Machine:
切割焦点在工件上面 1 cutting focus on the workpiece


This way we also become negative focal length, because the cutting point is not located on the surface of the cutting material or inside the cutting material, but is positioned above the cutting material. This method mainly uses materials with high cutting thickness. The main reason why this method locates the focus above the cutting material is mainly because the thick plate needs a large cutting width, otherwise the oxygen delivered by the nozzle is very likely to cause shortage and cause the cutting temperature to drop. However, a disadvantage of this method is that the cutting surface is relatively rough, which is not practical for high-precision cutting.

This method also becomes a positive focal length. When the workpiece you want to cut is stainless steel or aluminum steel plate, the mode of cutting point inside the workpiece is often used. However, a disadvantage of this method is that due to the focus principle cutting surface, the cutting width is relatively larger than the cutting point on the workpiece surface. At the same time, the cutting airflow required in this mode is larger, the temperature is sufficient, and the cutting perforation time is slightly longer. So when you choose the material of the workpiece is mainly stainless steel or aluminum material with high hardness.

This method also becomes 0 focal length. It is generally used when cutting workpieces such as SPC, SPH, SS41. When using, the focus of the cutting machine is selected close to the surface of the workpiece. The smoothness of the upper and lower surfaces of the workpiece in this mode is different. The cutting surface close to the focal point is relatively smooth, while the lower surface far from the cutting focal point appears rough. This mode should be based on the process requirements of the upper and lower surfaces in practical applications.
