Laser Machine Straw Hat Nozzle

• For thin plates below 3mm, the aperture of the selected nozzles should be φ1mm, so that the cutting gap will be relatively small. If the gap is larger, the gap will be thicker and the corner position will not be smooth.

• For cutting thick plates of 3mm-10mm, choose φ1.5mm. The heat dissipation area is relatively large, which will slow down the airflow and make the cutting more stable.

• When cutting plates of more than 10mm, fiber laser nozzles with a diameter of 2mm or more are generally selected.

The difference between single layer nozzle and double layer nozzle

• The single-layer nozzle uses nitrogen and air as auxiliary gases to cut stainless steel, aluminum, copper, etc.

• The double-layer nozzle uses oxygen as an auxiliary gas to cut iron plates, etc.
