The main wearing parts of laser cutting machine:
1. The protective lens mainly includes the upper protective lens and the lower protective lens, and the lower protective lens is generally vulnerable.
2. Ceramic ring
3. Nozzles are divided into single and double nozzles, thin plates below 1.3mm: use φ1.5mm, the cutting surface will be thinner, use φ2mm, the cutting surface will be thicker, and the corners are prone to melt stains. Thick plates over 3mm: due to higher cutting power, The relative heat dissipation time is longer, and the relative cutting time also increases. With φ1.5mm, the gas diffusion area is small, so Not very stable in use, but basically usable. With φ2mm, the gas diffusion area is larger and the gas flow rate is faster Slow, so it is more stable when cutting. The hole diameter of φ2.5mm can only be used for cutting thick plates over 10mm. In summary, the size of the nozzle aperture has a serious impact on the cutting quality and perforation quality. At present, laser cutting Use more nozzles with φ1.5mm and φ2mm apertures.
Regular cleaning of optical components: The optical components of the laser cutting machine include lenses, mirrors, etc. These parts require regular cleaning to remove dust and dirt to ensure the quality of laser beam transmission. Use cleaning paper and cleaning fluid To clean, be careful not to touch the surface of the lens to avoid scratches or fingerprints.
Check the status of the laser: Regularly check the output power and wavelength of the laser to ensure the normal operation of the laser work regularly. If the laser is found to be abnormal, it needs to be repaired or replaced in time.
Replacement of filters and lenses: The filters and lenses of laser cutting machines are often damaged by the laser beam worn or damaged. These parts need to be replaced regularly to ensure the cutting effect and stable work of the laser cutting machine sex.
Regularly check and replace the gas pipeline: the laser cutting machine needs to use auxiliary gas for cutting. regular inspection and Replace the gas pipeline to ensure the smooth flow of gas to ensure cutting quality and efficiency.
Regularly check and replace the water cooling system: The laser needs to be cooled by water to keep the temperature stable. regular inspection and replace the water pump, water tank and water pipes in the water cooling system to ensure the normal operation of the water cooling system.
Regularly calibrate the optical path: regularly calibrate the optical path of the laser to ensure the transmission quality and cutting accuracy of the laser beam.
Keep the working environment clean: keep the working environment of the laser cutting machine clean and tidy, avoid dust, oil and Damage to the laser and optical components from debris, etc.
