During the debugging process before the laser cutting head is used, in order to adapt to different materials, different thicknesses and different shapes, it is necessary to adjust some parameters of the laser cutting head, so how to adjust?

1. Cutting speed
Cutting speed is affected by factors such as laser power density, material properties, and material thickness. When other parameters remain unchanged, factors such as changing the power of the laser cutting head (within the required range), changing the beam mode, and changing the focus size will all have an impact on the cutting.
When cutting thin metals, the cutting speed can still maintain good cutting quality within a relatively specified range. For thicker metals, a slower cutting speed will cause the hot melt material to ablate the cutting surface, making the cutting surface rough and failing to meet the cutting quality requirements.
2. Laser output power
For continuous wave output lasers, laser power and mode have important effects on cutting. Under low power conditions, higher power density and better cutting quality can usually be obtained at the focal point.
3. Adjust the focus position
The laser power density affects the cutting speed. After knowing which focal length lens to use, the relative position of focal length and workpiece surface is very important for cutting quality. Due to the high power density at the focus, in most cases, the focus position is only on the surface of the workpiece or slightly below the surface of the workpiece. During the entire cutting process, not changing the relative position of the focus and the workpiece is an important condition to ensure stable cutting quality. Sometimes due to poor cooling, the lens will be heated, resulting in a change in focal length, requiring timely adjustment.
4. Gas pressure
The type and pressure of the gas have a great influence on the cutting speed of the laser cutting head. For most metal laser cutting, reactive gas (only oxygen) and incandescent metal form an oxidative exothermic reaction. The extra heat can speed up the cutting speed by 1/3 to 1/2.
