Metal Cutting Machine

Metal cutting machine as a new type of tool is now more and more mature applied to various industries. So how to use laser cutting in the end, laser cutting how good is it? First, the laser energy in the form of light concentrated into a high-density beam, the beam is transmitted to the working surface, generate enough heat to melt the material, combined with the beam coaxial high-pressure gas directly to remove the metal melt, so as to achieve the purpose of cutting , Which shows that the laser cutting machine with a mechanical processing is essentially different. It is the use of laser beam emitted from the laser generator, the external circuit system, focusing into a high power density of the laser beam irradiation conditions, the laser heat absorbed by the workpiece material, the workpiece temperature rose sharply, reaching the boiling point, the material began to vaporize and form The hole, with the relative movement of the beam and the workpiece, eventually causes the material to form a kerf. Cutting process parameters (cutting speed, laser power, gas pressure, etc.) and the trajectory are controlled by the numerical control system, kerf slag was a certain pressure of the auxiliary gas blowing. In general, the quality of laser cutting can be measured by the following six criteria. The company is located in:
