Focus position of automatic fiber laser cutting machine
Fully automatic fiber laser cutting machine Fiber laser cutting machine focus position analysis Fiber laser cutting machine is more and more widely used due to its excellent beam quality and cutting effect. Regarding the focus position of the laser cutting machine, there are three methods, which are analyzed below. When the focus is on the surface of the sheet, it also becomes 0 focal length. When using, the focus of the cutting machine is selected close to the surface of the workpiece. In this mode, the upper and lower surfaces of the workpiece are different in smoothness. Generally speaking, the cutting surface close to the focus is relatively smooth. The lower surface away from the cutting focus appears rough. This mode should be determined according to the process requirements of the upper surface and the lower surface in the actual application. This way the focus is inside the plate also becomes a positive focal length. When the workpiece you need to cut is stainless steel or aluminum steel plate, the mode that the cutting point is inside the workpiece is often used. But a disadvantage of this method is that due to the focus principle, the cutting width is relatively larger than the cutting point on the surface of the workpiece. At the same time, the cutting airflow required in this mode is large, the temperature is sufficient, and the cutting and piercing time is slightly longer. So when you choose the material of the workpiece is mainly stainless steel or aluminum with high hardness. The method of focusing on the plate is also a negative focal length, because the cutting point is not located on the surface of the cutting material or inside the cutting material, but positioned above the cutting material.
This method of automatic fiber laser cutting machine mainly uses and cuts materials with high thickness. The reason why the focus is positioned above the cutting material in this way is mainly because the thick plate requires a large cutting width, otherwise the oxygen delivered by the nozzle is very likely to be insufficient and cause the cutting temperature to drop. But one disadvantage of this method is that the cutting surface is relatively rough and not suitable for high-precision cutting. In short, the focus position should be different according to the material being cut. Fiber laser cutting machine, laser engraving machine, marking machine, welding machine, fan! Laser cutting machines, light engraving machines, marking machines, welding machines, and camouflage are here for your service! There are also large quantities of overseas companies who come to purchase machinery and equipment! Because buying machines at the exhibition is really cost-effective! Really cost-effective! There are many supporting gifts! And there are also many value-added services! Partners in Jiangsu, Zhejiang and Shanghai, don’t you consider buying new high-performance equipment? The Shanghai exhibition that Lecai participated in not only attracts friends from the domestic advertising industry from all over the world, Today, the industry is increasingly competitive, bringing revolutionary changes to industries such as spokes, flags, and printing. Let's see if the company can withdraw cash. Today, with full coverage of high technology, exquisite printing can be completed even at high speed and low resolution, and high-quality printing without graininess. For cutting machines. Not only in high-resolution printing, looking at k-color and easy-color. Even in the 4-color mode, by jetting 3 different sizes of ink droplets, I heard that the engraving machine.
