How to improve the cutting precision of laser cutting machine?
Nowadyas more and more people choose fiber laser cutting machine for sheet metal processing. There are many factors affecting the cutting quality.
Factors that affecting the cutting quality
Firstly, the size of the spot after the laser beam is focused;
Secondly, the positioning accuracy of the working table;
Thirdly, the thickness of the workpiece;
Fourthly, the workpiece material. The smaller the laser beam spot, the higher the precision of the workbench. The thinner the workpiece, the more conducive to improve the quality of cutting.
How to improve the cutting precision of laser cutting machine
Firstly, it is necessary to achieve accurate control of the focus.
The smaller the focal depth of the focusing lens is, the smaller the spot at the focal point will be. Therefore, the focal position can be effectively controlled on the metal surface to improve the cutting quality.
Secondly, the cutting and piercing technology is optimized
Because the laser cutting machine belongs to thermal cutting, it is also necessary to penetrate a small hole in the metal plate. And then the laser beam begins to cut the plate at the small hole.
Thirdly, optimize nozzle design and flow control technology
During the processing of sheet metal by laser cutting machine, gas is squeezed by nozzle and acted on the surface of the material by laser beam. The basic requirements for airflow are large flow rate and fast speed. Then can ensure that there is enough gas and material thermal reaction. At the same time, there is enough gas flow to blow away the slag.
The above content is the main method to improve the cutting quality of laser cutting machine. In fact, laser cutting machine still has a lot of unique use skills to the improvement of cutting quality. Here, we remind customers to pay attention to learning. Keep abreast of the latest industry trends, and improve the performance of the machine.
