The optical fiber laser cutting machine will produce dust in the laser cutting process. The dust is not only harmful to the machine and equipment, but also polluting the air and affecting the health of the body. Therefore, efficient dust removal during the production process of the machine is crucial.

The current optical fiber laser cutting machine mainly has two dust removal methods: 1. The exhaust system, as its name implies, is to discharge the dust particles into the atmosphere through the exhaust fan. Although this method is simple, it does not fundamentally solve the dust problem, and the pollution to the air environment is unavoidable; 2. With the use of filtering technology, filtering and dedusting equipment has appeared as early as the 1970s, and it has the advantages of small size and high efficiency. However, due to its small capacity and low filtering wind speed, it cannot handle large air volume and has a narrow application range. Due to the emergence of new filter materials and the improvement of dust removal equipment design, filter type dust removal equipment is gradually applied in dust removal projects. The features of filter element dust removal equipment are as follows:

1. It is used for filter material folding, with large layout density, compact structure and small volume of dedusting equipment, and high rigidity of filter material performance requirements;

2. The filter element is small in height and easy to install;

3. Compared with dedusting equipment of the same volume, the filtering area is relatively large, the filtering wind speed is small, and the resistance is small;

4. Both ends of the filter material folding grid shall be sealed strictly without air leakage, or the effect will be reduced.

The dust particle size of the optical fiber laser cutting machine is very small, the flue gas may contain oil and sparks, and its filter has a high probability of ignition. The filter material of the dust remover itself must be of good quality before it can be used for a long time. The use of film coated flame retardant filter material is necessary. At the same time, in combination with reasonable filtering wind speed, internal split distribution of the six dust removers, efficient pulse ash removal system, and reasonably selected fans, it can ensure the long-term safe operation of the cutting dust remover.

Therefore, in order to effectively remove dust, it is recommended that the optical fiber laser cutting machine be equipped with filtering and dust removal equipment to effectively remove dust.
