3 Focal Points Of Laser Cutting Machine

Dec 22.2017

1. the cutting focus is on the workpiece
In this way, we also become a negative focus, because the cutting point is not located on the surface of the cutting material, nor on the inside of the cutting material, but on the top of the cutting material. This method is mainly used in material with high cutting thickness. This way focuses on cutting the material above, mainly because the thickness needed for the thick plate is large, otherwise the oxygen transported by the nozzle is very easy to appear, which leads to the lack of cutting temperature. One drawback of this approach, however, is that the cutting surface is relatively rough and not too solid for high precision cutting.

2. the cutting focus is inside the workpiece
This way also becomes a positive focal length. When you need to cut the workpiece for stainless steel or aluminum steel plate, it is often used to cut the pattern inside the workpiece. But one drawback of this way is that because the focus principle cuts the surface, the cutting amplitude is bigger than the cutting point on the workpiece surface. At the same time, the cutting air flow needs to be large, the temperature is enough and the cutting time is a bit longer. So when you choose the material of the workpiece mainly for stainless steel or aluminum material hardness of the material when the material is selected.

3. the cutting focus is on the surface of the workpiece
This way has also become the 0 focus, generally seen in SPC, SPH, SS41 cutting, the focus of the use of the time machine in close to the surface of the workpiece, the workpiece under the pattern of surface smoothness is not the same, generally close to the focus of the cutting surface is relatively smooth, while cutting away from the focus the surface is rough. This model should be based on the technical requirements of the upper and lower surfaces of the actual application.

Anyways, we use laser cutting machine to process different parts, so we need to use different focus modes. We can play a better performance advantage of laser cutting machine.
