Many times, when we are doing laser cutting, we want to achieve a mirror effect. Today, we will share six knowledge points about mirror effect.
1. Control the cutting speed. The cutting speed is too fast, the material burns incompletely, and the workpiece cannot be cut through. If the speed is too slow, it will cause excessive combustion and the workpiece will melt and deform. On the premise of ensuring the quality of the workpiece, the cutting speed should be increased as much as possible.
2. Adjust the nozzle height. The nozzle height can affect the beam quality, oxygen purity, and airflow direction. The lower the nozzle, the better the beam quality, the higher the oxygen purity, and the smaller the airflow direction, so the gloss cutting should be as low as possible.
3. Adjust the cutting pressure. In carbon steel oxygen cutting, the combustion of the material releases a large amount of heat, so the oxygen pressure should not be too high. Generally speaking, the lower the pressure within the cutting range, the brighter the cutting surface. However, in order to ensure the stability of the cutting, a certain proportion is usually determined based on the cutting pressure.
4. Adjust the cutting power. For sheets of different thicknesses, the larger the thickness, the higher the required power.
5. Adjust the cutting focus. The beam emitted by the nozzle of a fiber laser has a certain diameter, and smaller nozzles are usually used when cutting bright surfaces. If the focus is too large, it can cause the nozzle to heat up, affecting cutting quality and stability, and even directly causing nozzle damage. Therefore, it is necessary to find a nozzle size that can withstand a larger focal length value and then make adjustments.
6. Choose nozzle size. The smaller the half nozzle, the brighter the cutting section and the better the effect.
