From the perspective of the development trend of the manufacturing and processing industry, laser equipment has been widely used in the metal sheet material processing and manufacturing industry, and the domestic CNC machine tool laser cutting CNC lathe has a rapid development trend. Little do they know that equipment manufacturers have less scientific research on the harm of smoke and dust caused by laser cutting metal sheet materials to the body and the natural environment, resulting in poor awareness of safety protection.

Some manufacturers use a simple fan design out of cost considerations, resulting in a less effective smoke and dust removal. At this stage, various types of laser processing equipment are basically equipped with laser soot and smoke purifiers as standard, and some well-known domestic and foreign manufacturing and processing enterprises are also equipped with some air extractor for eyelash extension, but most manufacturers are more casual, and some are only paired with one The exhaust fan will discharge smoke and dust without purification, and continue to pollute the surrounding area. Even some companies do not know the existence of air extractor for laser machines, and do not plan to support these air extractor for co2 laser machines.

Hazards of industrial smoke

(1) The smoke and dust released during laser processing are mainly metal material dust and thick smoke.

(2) If there is grease on the surface of metal material, it may cause more complicated nitrogen oxide gas and dust, generally xylene, xylene, indoor formaldehyde, o-xylene, formate, toluene, tolualdehyde, butyl alcohol, butyrate, etc.

(3) When the high-pressure polyethylene protective film is applied on the surface of the metal material, ester and cyclohexanol chemicals will be released during processing, and a significant odor will be felt.

(4) 97% of the smoke and dust caused by laser processing and manufacturing are less than 5.7µm in diameter, which means that most of them can be inhaled into the body, causing respiratory system, skin diseases, and carcinogens.

(5) A lot of smoke and dust will not only pollute the environment, but also endanger the service life of the laser head if it is not rectified immediately!
