With laser machine is widely promoted in all walks of life, more and more users benefit. Laser engraving machine is master and use many small craft laser machining process, especially the non-metallic and non-metallic laser engraving machine marking machine is widely used in wood, glass, bamboo bamboo, folk paper-cut, shadow puppets and other processing industries. Laser cutting machine a wide range of applications in industrial production and processing of laser machine manufacturers, such as sponges cut packaging, industrial foam cutting, sheet metal cutting, sheet metal cutting, and other kitchen utensils. With laser applications in industry to increase the share of the laser machine types are also increasing, so in the future will have a huge space for development. Laser cutting laser melting melting laser cutting machine brand, with the flow of the molten material ejected after the workpiece is partially melted. Because the transfer material in its liquid state occurs only case, so that the melting process is known as laser cutting. Laser beam cutting coupled with high purity inert gas to promote the melted material leaving slotted, and the gas itself is not involved in cutting. Laser cutting can be compared gasification melting cutting higher cutting speeds. Gasification is generally higher than the energy required for the energy required to melt the material. In cutting laser melting, a laser beam is absorbed only partially. The maximum cutting speed increased as the laser power increased, and increases with increasing melting temperature of the material sheet thickness and almost inversely proportional to decreases. Under certain circumstances the laser power, limiting factor is the cutting pressure and material joints of the thermal conductivity. Laser cutting for melting iron material and titanium oxide can be obtained without incisions. But less than the melting gasifier to produce a laser power density, for steel material, in between 104W / cm2 ~ 105 W / cm2. Common sources emitting laser source (such as lights, flames, sun, etc. luminescence) is due to the material when subjected to external energy (such as solar energy, electricity, heat, etc.) the role of electrons in atoms will absorb external energy from low energy level transition to the high energy level, that atoms are excited. The excitation process is a "stimulated absorption" process. High energy level of electrons in a very short lifetime (typically 8 to 10 seconds), in the absence of external action under spontaneously transition to a low energy level, will produce light (electromagnetic) radiation transition. This radiation is called spontaneous emission. Atomic spontaneous emission process is a completely random process, light-emitting atoms each process independent, unrelated, that the radiation emitted in the direction of the light is random shooting in all directions, while not the phase, the polarization state is also different are not the same. Since the excitation energy level has a width, the frequency of the emitted light is not a single, but a range. Under normal conditions of thermal equilibrium laser machine, the density of atoms in a high energy level, than in the low atomic number density of low energy level, which is level with the level as in the size of the atomic number density increases exponentially reduced E small, which is famous for the Boltzmann distribution. Seen at 20 ℃, almost all of the hydrogen atoms in the ground state, make atom light emission, energy must be provided outside excited states of atoms arrive, so the ordinary light emission is broad contains two processes stimulated absorption and spontaneous radiation. In general, the energy radiated by this source of light is not strong, with emission in all directions, but the energy dispersion of the laser machining | Qingdao Tianrun High Frequency (certified) | laser machine from Qingdao Tianrun High Frequency Electric Co.
