Qingdao Tianrun (www.gaozhoubo.com.cn) is specialized in "high frequency induction heating equipment, ultrasonic plastic welding machine, welding machine, laser cutting machine" of the enterprise, the company adhering to the "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Yan Lidong. 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. Spontaneous emission process atoms is a completely random process, the process of each light-emitting light emitting atoms are each independently laser cutting machine, unrelated, i.e. radiation in the emission direction of the light is directed in all directions random, is not otherwise phase, polarization state also vary. Since the excitation energy level has a width, the frequency of the emitted light is not a single laser cutting machine price, and there is a range. Under normal conditions of thermal equilibrium, at a high energy level on the atomic number density, and low energy level than in the low atomic number density, it is because in level with the level of the size of atoms, the density of which increases E decreases exponentially, This is the famous 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 cutting machine as a new tool to use increasingly sophisticated variety of industries, including laser cutting machine, laser engraving machine, laser marking machine, laser welding machines. So in the end is how the use of laser cutting and laser cutting is good or bad but how different? First, the energy of the laser light is concentrated into the form of a high-density beam, the beam delivered to the work surface, to generate enough heat to melt the material, combined with the high pressure gas coaxial with the beam directly to the molten metal is removed, so as to achieve the purpose of cutting, This shows that the difference is essentially the same machine laser cutting machining. It is the use of a laser generator emitted from the laser beam, via the optical system, a high power density focused laser beam irradiation conditions, the laser heat is absorbed workpiece material small laser cutting machine, a sharp rise in temperature of the workpiece, after reaching the boiling point, the material begins to vaporization and formation of holes, with high pressure air, with the movement of the laser beam and the relative position of the cutting machine workpiece supply, ultimately the material forms slits. Process parameters (cutting speed, laser power, gas pressure, etc.) and when the slit trajectory by CNC control system, slag slotted auxiliary gas at a certain pressure is blowing.
