Cutting high light reflective materials with metal fiber laser cutting machine is a crucial one faced by many metal material laser cutting machine manufacturers. Specular metal materials, including copper and aluminum, cannot be cut by metal laser cutting machine for a long time. This kind of material is also a very common material in people's daily production and processing.
High reflective metal materials have always been difficult to cut by metal laser cutting machines, including copper, aluminum, gold and other metal materials, which are also common materials in our daily processing. Solving the problem of cutting high reflective materials by metal laser cutting machines is an important problem for many metal laser cutting machine manufacturers.   
Why is it necessary to add auxiliary gas to cut highly reflective metal materials? When the metal laser cutting machine cuts metal copper, the added auxiliary gas reacts with the material under high temperature conditions to increase the cutting speed. For example, the combustion supporting effect can be achieved by using oxygen. For laser cutting equipment, nitrogen is an auxiliary gas to improve the cutting effect. For copper materials below 1mm, metal laser cutting machine can be used for processing.   
Therefore, when using the metal laser cutting machine, don't worry about whether it can cut. At this time, we should pay attention to the processing effect, so it is best to use nitrogen as the auxiliary gas. When the thickness of metal copper reaches 2mm, nitrogen cannot be used for processing. At this time, oxygen must be added and oxidized to realize cutting.
