In recent years, with the increasing calls for energy saving, emission reduction and green environmental protection around us, Jinan REBOUND CNC believes that enterprises in the south of my country with moderate cutting processing volume can give priority to using plasma underwater cutting method. The reason is: in addition to the good economy, what we value more is the efficiency of its smoke and dust control and its good sustainability. After all, under the current situation, when selecting equipment, the pros and cons of its environmental performance often have a vote. veto power.

As we all know, CNC plasma cutting machine often use dry processing or wet processing to remove dust generated during processing.

In recent years, my country's manufacturing industry has shown a rapid growth trend, and the amount of steel plate cutting processing has increased sharply. People are eager to maximize the efficiency of cutting processing. Therefore, the dry type has advantages in terms of cutting speed, cutting quality, and shortening the time for changing the upper and lower plates. Plasma cutting has gradually become a trend. Of course, we should not ignore the possible adverse effects of blindly following the trend, because our past work has had too many experiences and lessons in this regard.

The dry processing method (dry cutting) is to add a set of smoke and dust collection device to the cutting work platform, and directly transport the collected smoke and dust to the smoke and dust filter and purification equipment, and then discharge it after the treatment reaches the standard. The smoke and dust generated by plasma cutting are basically formed below the workpiece incision, so the suction-type negative pressure cutting platform has become the most common smoke and dust capture device. In order to save equipment investment and improve the extraction efficiency, that is, to achieve a higher amount of dust collection with a smaller suction volume - only the area that is in the cutting process is vacuumed, so the cutting platform along the main guide rail of the cutting machine will be removed. Divided into (even) closed small areas with air outlets on the side. The working form of the suction port is divided into a side suction mobile suction port and a valve suction port on the side wall of the vacuum chamber. Among them, the former is widely used because of its simple structure, reliable operation and good dust removal effect.

The so-called wet processing method of CNC plasma cutting machine (wet cutting) is to make a waterbed cutting platform, place the workpiece in water or water surface, and then complete the cutting operation underwater or close to the water surface, and use water to capture the cutting process. so as to achieve the purpose of purifying the environment.

For most new users who lacked practical experience in this aspect in the past, which of the above methods is more suitable for production, it is difficult to give a standard judgment.
