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