Q: Which master please teach about aluminum alloy doors and windows under the material calculation method? Flattened; push-pull can be the best example. Thank you!: laser cutting Laser cutting is a new type of processing technology, has been widely used in metal cutting, glass cutting, sculpture and other industries. The laser is a kind of light, which is produced by the transition of atoms (molecules or ions, etc.), but it is different from ordinary light that the laser depends only on spontaneous emission only in the first short time, and the process is completely determined by laser radiation, So that the laser has a high coherence, high strength, high direction, laser cutting machine through the laser to produce laser, the mirror transmission and through the cluster mirror to the processed items, so that processed items (surface) by the strong heat and temperature A sharp increase, so that the point due to high temperature and quickly melt or vaporization, with the laser head of the trajectory to achieve the purpose of processing. The advantages of laser cutting machine are: the processing of the workpiece without mechanical pressure, so cut out the product with high precision, no secondary processing; cutting speed, easy operation, high degree of automation; can cut any complex shape of the product, Cut, the model compression process is more preferred, although the processing rate is slower than the punching, but it saves mold costs, low economic costs. But for the thickness of more than 6mm aluminum alloy sheet, the use of laser processing, cutting effect is not good, and the equipment on the use of high environmental requirements, equipment failure in the service after a long time.
