How to operate fiber laser cutting machine to cut coated materials?

May 10,2023 | TOPTEK

Many metallic materials require special handling to maintain their integrity, otherwise they are prone to scratches during many transfer projects. For workpieces with high material requirements, this kind of problem is very difficult, so many metal materials will have coatings. Metal coating can ensure that the raw material is damaged by friction as little as possible during the transfer process, which has higher requirements for laser cutting machine cutting metal. The operation process of fiber laser cutting machine cutting coated metal.

The laser cutting machine must first cut the coated metal plate so that the side of the coated film is facing up, first cut the film, and then cut the metal plate after cutting the coated film. This secondary processing can effectively guarantee the quality of the material. How big the laser tube should be depends on the type and thickness of our board.

So, why don't we put a layer of film down, so that we can not only avoid damage to the material by the table, but also complete the cutting in one go? Those who have tried it should come to this conclusion: cutting after debugging the equipment, if the coating is cut off at one time, it is easy to leave residues on the coating during laser cutting, which has a great impact on the quality of the finished product. Although there are certain advantages in speed, the yield is low and the product quality is poor. Therefore, it is recommended to cut the coating before cutting the sheet metal.
