1. Add cooling point at the corner

When cutting sharp-corner metal sheets, the location where overburning is more likely to occur is often at the sharp corners. Overburning will cut the sharp corners into rounds. At this time, add a cooling point at the sharp corners and stop at the sharp corners. Click, blow.

2: Use high power laser generator

Fiber laser cutting machine can use higher power laser when cutting carbon steel,Adopting the bright surface cutting process,can avoid pverburning effectively, and this cutting process can cut finished products with no burrs and bright cut surfaces

3. Cutting with nitrogen

In sheet metal cutting with oxygen as the auxiliary gas, nitrogen can be used for cutting. When cutting with nitrogen, the material is completely melted by laser energy, and the nitrogen is blown out of the slit to avoid inappropriate chemical reactions. The temperature in the melting point region is relatively low, coupled with the cooling and protection of nitrogen, the response is stable and uniform, and the cutting quality is high. The section is fine and smooth, the surface roughness is low, and there is no oxide layer.

4: Increase the air pressure

When the fiber laser cutting machine is used to process aluminum alloy and stainless steel, the auxiliary gas used is nitrogen or air, and edge burning will not occur during the cutting process. However, due to the high temperature of the material inside the small hole, the slagging phenomenon on the inside will be reduced. More frequently. In this case, burrs and dross can be reduced by increasing the pressure of the auxiliary gas.
