How to Improve the Accuracy of Fiber Laser Cutting Machine
With the development of modern laser technology, the fiber laser cutting machine have been applying in progressive metal industry.
In the subsequent development process, laser cutting technology was gradually applied in sheet metal processing, plastic, wood and other materials cutting.
It is gradually becoming an indispensable and important process in industrial production.
So, how to increase the laser cutting accuracy?
First, it needs to achieve accurate control of the laser focus.
The smaller focal depth of the focusing lens is, the smaller spot at the focal point will be.
Therefore, the focus position can control on the metal surface very effect to improve the cutting quality.
Secondly, optimize the cutting and piercing technology.
Because the laser cutting machine work process is hot cutting processing, it needs to penetrate a small hole in the metal plate, and then the laser beam starts to cut the plate from the small hole.
Third, optimize nozzle design and flow control technology.
During the cutting processing of sheet metal, oxygen is squeezed by a nozzle and acted on the surface of the material to be cut by laser beam
The basic requirements for airflow are large flow rate and fast speed, so as to ensure that there is enough oxygen thermal reacts with material, at the same time, there is enough gas flow to blow away the slag.
Generally speaking, the laser factors affecting the cutting quality, it mainly includes the following aspects: first, the size of the spot;
Secondly, the positioning accuracy of the work table;
The third is the thickness of the workpiece;
The fourth is the workpiece material.
The smaller laser beam spot is, the higher the precision of the workbench, the thinner the workpiece thickness is, the more conducive to improve the quality of cutting.
