The cutting process of highly reflective materials is often challenging and difficult for many fiber laser cutting equipment manufacturers to solve. However, as common high reflective materials such as copper, aluminum, and gold, they also require frequent processing in daily production.
One of the solutions proposed by many manufacturers is to use corresponding auxiliary gases. When cutting copper with a fiber laser cutting machine, the auxiliary gas can effectively increase the cutting speed after the material melts and reacts.
The use of oxygen as an auxiliary gas and nitrogen as an auxiliary gas can also improve the cutting speed and effectiveness of fiber laser cutting machines. Of course, for copper plates below 1mm, no auxiliary gas is required for cutting and processing.
Why is it necessary to use auxiliary gas when cutting high reflective materials to increase the speed of cutting them?
1. The auxiliary gas undoubtedly enhances the cutting effect;
2. By assisting the chemical reaction between gas and metal materials, the cutting ability can be improved;
3. Help the equipment blow away slag from the cutting area to clean the cutting seam;
4. Cooling the area near the cutting seam and protecting the focusing lens;
The selection of gas pressure and type is crucial for the cutting process. The selection of the type of auxiliary gas has a certain impact on the cutting performance, including cutting speed, cutting thickness, etc.
The processing operation of fiber laser cutting machine is a professional technology that requires high experience and technical skills from the operator. Only with sufficient technology and suitable cutting methods can better results be achieved when processing high reflective materials such as copper.
