Fiber Laser cutting is a heated cutting process that uses a concentrated high-energy-density light beam as the primary heat source to light the workpiece, causing the irradiated materials to melt quickly, evaporate, ablate, or reach the internal temperature. Simultaneously, high-speed airflow that is concentric with the beam is used to blast away molten material, allowing the workpiece to be sliced. With the maturation and perfection of high power fiber laser generator technology in recent years, its application area has been steadily increasing. The fiber laser milling machine manufactured by has become a center of industry research and development.
The following are some of the basic fiber laser cutting tips and techniques to help you out in the cutting process:
Concerns regarding materials:
A fiber laser cannot cut effectively through low-quality material. When an operator removes a component from the nest and notices severe striations, the trouble is frequently traced back to the material. When a beam strikes a plate edge with mill scale, craters, or other defects, a hot spot can form that enters the material and includes a vein along the side of the cut. Pitting and cratering can also alter the dynamics of the assist gas flow, therefore changing the way the laser cuts. The more consistent the laser cutting, the smoother the plate.
Take into account all of the small details:
If anything isn’t working properly with a fiber laser, it’s usually not the focus, flow rate settings, nozzles offset, or other cutting-conditions ingredients. It’s frequently the little things: A beam that is not completely centered, requiring the operator to verify it with a tape shot, acrylic puck, or spark shot on a sacrificial plate (the spark and each pattern, if concentric around the nozzle, shows the operator if the beam is centered). If it isn’t the nozzle, it might be a small spot on the cover glass, a tab in the wrong location, or a thin web portion that causes parts to become unstable. Take care of the minor details, and the fiber laser will remain the fab shop’s incredibly productive workforce today and for many years to come.
Keep your cover glass clean:
A fabricator receives a new fiber machine and prepares to be amazed not just by its incredible speed but also by its ease of maintenance. After all, the operator and maintenance technician no longer have to be concerned about mirrors and gas resonators. They must clean the machine, chiller, and dust collector, but that is it. After a few days of installation and testing, the first shift operator arrives and begins the next task, only to discover that the machine is making horrible cuts. Why? He looks through the cover glass pane and notices a small spot. That is the perpetrator. He cleans or changes the cover glass pane that protects the sensitive op of the fiber laser.
