Laser cutting is to focus the laser emitted from the laser into a laser beam with high power density through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. With the movement of the relative position between the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting.
At present, there are many kinds of laser cutting machines, including CO2 laser cutting machine, fiber laser cutting machine, precision laser cutting machine and other different laser cutting machines, which not only use different lasers, but also have great differences in application. Different materials have different characteristics, and the absorption of laser is also different. Some materials may absorb the laser in this band, but not in other bands, which makes us choose laser equipment according to the specific material characteristics. For objects with different thicknesses, sizes and shapes, different laser equipment will also be used in the process of processing in order to obtain better processing results.
At present, there are three main application directions of laser equipment:
1、 It refers to the processing materials used for decoration, advertising, lamps, kitchenware, thin sheet metal parts, electrical cabinets, elevator panels, engineering boards, high and low switch cabinets. These materials are generally thin, 1-5mm thick stainless steel plate materials. With medium power excitation, it refers to cutting plastic (polymer), rubber, wood, paper products, leather and natural or synthetic organic materials. Because these kinds of materials are not metal products, The absorption of laser is also different, so this kind of material is best cut by CO2 laser cutting machine.
3、 It is low carbon steel with a thickness of 8-20mm and stainless steel with a thickness of 12mm. Such materials need high-power laser cutting machines to cut quickly and instantaneously. You can consider buying high-power fiber laser cutting machines or high-power CO2 laser cutting machines. Therefore, when choosing laser equipment, we should not only consider the characteristics of our products, but also consider the performance of laser equipment, so that we can find laser equipment suitable for our own industry products.
