Optical fiber laser cutting machine will generate a lot of heat when processing sheet metal.

Under normal conditions, the heat generated by cutting will diffuse to the processed sheet metal along the cutting seam and get enough cooling.

The outer side of the hole can be fully cooled during the processing of the small hole of the metal laser cutting machine.

Because the space for heat distribution is very small, the small hole part in the single hole is easy to cause excessive combustion and slag hanging.

How to avoid excessive combustion when using the laser cutting machine?

How to avoid excessive burning when cutting sheet metal with laser cutting machine?

Add cooling points at corners

When cutting sharp metal plates, the position where excessive combustion is more likely to occur is usually at the sharp corner.

Excessive burning will cut the sharp corners into a circle.

Then, you can add a cooling point at the sharp corner, pause at the sharp corner, and blow out the air.

Use high-power laser

When cutting carbon steel, a higher power laser can be used.

Bright surface cutting technology can effectively avoid excessive combustion.

And this cutting technology can cut a bright finished product without burr on the surface.

Nitrogen cutting

In sheet metal cutting with oxygen as auxiliary gas, nitrogen can be switched for cutting.

During nitrogen cutting, the material is completely melted by laser energy.

Nitrogen is blown out of the slit to avoid improper chemical reaction.

The temperature in the melting point zone is low, which has the cooling and protection effect of nitrogen, and the reaction is stable.

Uniform and high cutting quality. The section is fine and smooth, the surface roughness is low, and there is no oxide layer.
