Laser cutting is an efficient and accurate processing method, which is widely used in industrial manufacturing.
During laser cutting, the laser beam is emitted through the nozzle, and the diameter and shape of the nozzle will affect the focusing effect and cutting quality of the laser beam. With the increase of cutting time, the aperture of the nozzle will gradually become larger, resulting in a reduction in the focusing effect of the laser beam and a reduction in cutting quality. At this time, replacing the nozzle can effectively improve the efficiency and quality of laser cutting.
In the process of laser processing, the nozzle installed on the processing head of the laser processing equipment in order to perform the processing process is close to the heat source, so the nozzle needs to be replaced regularly; In addition, when processing materials of different thicknesses and different materials, it is also necessary to replace different specifications of nozzles. When laser cutting, the nozzle temperature will rise, manual replacement of the nozzle, you need to wait for the nozzle to cool and then replace, in the closed equipment with a large surround, manual replacement of the nozzle time is longer, extremely inconvenient. In addition, the spray produced during laser cutting is attached to the nozzle, affecting the processing accuracy of the parts and the life of the nozzle, and the surface of the nozzle needs to be polished regularly, but the efficiency of manual polishing is low, affecting the work process.
How to choose the right nozzle?
1. Nozzle material The nozzle material should be matched with the material to be cut to avoid increased nozzle wear and reduced cutting quality.
2. Nozzle shape Nozzle shape will affect the focusing effect and cutting quality of the laser beam.
3. Nozzle aperture Nozzle aperture should be selected according to the thickness of the material to be cut and the laser power.
Matters needing attention
Before replacing the nozzle, turn off the laser processing machine and wait for the nozzle to cool down to avoid burns.
After replacing the nozzle, test cutting should be carried out to check whether the cutting quality meets the requirements.
Pay attention to the installation position and direction of the nozzle to avoid the deterioration of cutting quality caused by installation errors.
