The laser stamping compound machine first uses a hole, and then uses a laser to gradually cut from the hole. With the further improvement of laser output power and the gradual improvement of technology, laser perforation has become popular. So what is the opening of the laser cutting machine? Lab air filter.

(1) Engineering blasting and perforation: The raw material is directly irradiated with a continuous laser to produce a dent in its core, and then the molten raw material is quickly eliminated by the laser beam coaxial oxygen flow to produce holes. Generally, the size of the hole is half of the wall thickness of the engineering blasting perforated plate with the thickness and average diameter of the plate. Therefore, the thickness of the plate’s engineering blasting perforation diameter is relatively large, not round, and it is not very suitable for the application of higher standards (such as crude oil). Sieve pipe), only for consumption. In addition, because the o2 working pressure of the perforation is the same as that of the cutting, the splashing is also relatively large. lab air filtration

(2) Pulse perforation: The highest output power of pulsed laser is used to melt or volatilize a small amount of raw materials, and gas or nitrogen is the more commonly used auxiliary vapor because of causticization, reducing hole expansion and air pressure lower than when cutting o2 Work pressure. Each laser pulse only causes a small particle to be ejected, which slowly penetrates, so it takes a few seconds to perforate the plate. Once the perforation is carried out, the assisting vapor is replaced by o2 for cutting. The perforation quality is better than the engineering blasting perforation with a smaller diameter. The laser used for this purpose must not only have a higher power; more importantly, the optical characteristics of the light, so the general diffuse CO2 laser cannot meet the requirements of laser cutting. lab dust collector
