Around the 1970s, laser cutting technology was first used in modern industrial production. In the subsequent development process, metal CNC fiber laser cutting machine were gradually applied to the cutting of different materials such as sheet metal processing, becoming an industrial An indispensable and important process in the production process.

Generally speaking, the factors that affect the cutting quality mainly include the following aspects: the first is the spot size of the laser beam after focusing; the second is the positioning accuracy of the worktable; the third is the thickness of the workpiece; the fourth is the workpiece material. The smaller the laser beam spot, the higher the table precision, and the thinner the workpiece thickness, the better the cutting quality is.

Improve cutting accuracy

First, to achieve accurate control of the focus point. The smaller the focal depth of the focusing lens, the smaller the light spot at the focal point, so it can effectively control the focal position on the metal surface and improve the cutting quality.

Second, optimize the cutting and perforating technology. Since the metal CNC fiber laser cutting machine belongs to thermal cutting, it is also necessary to penetrate a small hole in the metal plate first, and then the laser beam starts to cut the plate from the small hole.

Third, optimize nozzle design and airflow control technology. In the process of processing the sheet metal by the metal CNC fiber laser cutting machine, the oxygen is squeezed through the nozzle and the laser beam acts on the surface of the material to be cut.

The basic requirements for the air flow are large flow and high speed, so as to ensure that there is enough oxygen to react thermally with the material, and at the same time, there is also enough air flow to blow away the slag.

The above content is the main method to improve the cutting quality of metal numerical control fiber laser cutting machine. In fact, metal numerical control fiber laser cutting machine has many unique use tips, which are related to the improvement of cutting quality. We hereby remind our customers to pay attention to learning and timely. Keep abreast of the latest industry trends and improve machine performance.
