The meaning of the word "LASER" is "Light Amplification by Stimulated Emission of Radiation". In order to further increase the efficiency in cutting, the efficiency is increased by adding nitrogen and helium gas to the carbon dioxide gas. The cutting process performed on various machines with the obtained laser beam is called Laser Cutting.
Focusing of the laser beam can be done with a special lens or conical mirror that occurs in the laser cutting head. The beam must be fully focused so that the shape of the focal point and the energy density at that point are perfectly circular, uniform, and centered within the nozzle. By focusing a wide beam on a sensitive point, the thermal intensity at that point can be increased. Consider using a magnifying glass to focus the sun's rays on the leaves and what kind of flame it might cause. Now consider concentrating 6 KW of energy in one spot and imagine how hot that spot could be.
High power density can cause the material to heat up quickly, melt and partially or completely evaporate. When cutting low-carbon steel, the heat of the laser beam is sufficient to trigger the typical "oxygen fuel" combustion process, so the resulting high-shear beam can easily cut through metal. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high-pressure nitrogen can be used to fix the molten metal.
In the laser cutting machine, the laser cutting head can be easily cut by moving over the metal parts to be cut. The capacitive height control system can keep the distance between the open end and the cutting board. In terms of cutting quality, the importance of this distance is very important, because if the focus is not well adjusted, efficiency will not be achieved. You can increase or decrease the cut quality by raising or decreasing the focus directly above, just above or below the panel.
There are many parameters that affect the cutting quality, but if all these parameters are properly controlled, the laser cutting process will be of good quality, reliable and perfect.
