Six methods for laser cutting machine to realize bright surface cutting

Today, the Laser cutting machine manufacturer Ande Laser will talk to you about the six methods of laser cutting machine to achieve bright surface cutting.

In the processing technology of the laser cutting machine, the cross section of carbon steel can be cut very smoothly to achieve a "mirror surface" effect, commonly known as "smooth cutting". Bright surface cutting is mainly used for medium-thick carbon steel. If the steel plate is too thin or too thick, bright surface cutting cannot be achieved.

1. Control the cutting speed. If the cutting speed is too fast, the material will burn 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 height of the nozzle will affect the beam quality, oxygen purity and gas flow direction. The lower the nozzle, the better the beam quality, the higher the oxygen purity, and the smaller the airflow direction, so the cutting of the bright surface should be as low as possible.


3. Adjust the cutting pressure. In carbon steel oxygen cutting, the combustion of the material will release a lot of heat, so the oxygen pressure cannot be too high. Generally speaking, the lower the pressure in the cutting range, the brighter the cutting section, but in order to ensure the stability of the cutting, a certain percentage is usually based on the cutting pressure.


4. Adjust the cutting power. For plates of different thicknesses, the greater the thickness, the higher the power required.


5. Adjust the cutting focus. The light beam emitted by the fiber laser from the nozzle has a certain diameter. When cutting the bright surface, a smaller nozzle is usually used. If the focus is too large, it will cause the nozzle to heat up, affect the cutting quality and stability, and even directly damage the nozzle. Therefore, it is necessary to find the large focus value that the nozzle size can withstand, and then adjust it.


6. Select the nozzle size. The smaller the half nozzle, the brighter the cutting section and the better the effect.
