With the continuous improvement of processing precision and efficiency requirements of sheet metal enterprises, laser cutting machines have gradually become mainstream processing equipment. Laser cutting machines can be distinguished according to the type of laser. Each type has its own advantages and disadvantages. Now there are three general types:
First, CO2 laser cutting machine
CO2 laser cutting machine, many early cutting 6-25mm steel plate, but the photoelectric conversion rate of CO2 laser is only about 10%, due to the large loss of laser maintenance, the host power consumption is too large to overcome the factors, in recent years, by the fiber The huge impact of the laser cutting machine, the metal cutting market is in a state of significant shrinkage. The CO2 laser has a wavelength of 10.6 μm and is easily absorbed by non-metals. It is suitable for high-quality cutting of non-metallic materials such as wood, acrylic, PP, and plexiglass.
Second, YAG (solid) laser cutting machine
The overall price of YAG solid-state laser cutting machine is low, and the energy efficiency is generally less than 3%. At present, the output power of the product is mostly below 600W, which is mainly used for punching and spot welding and thin plate cutting. Its green laser beam can be applied in the case of pulse or continuous wave. It has short wavelength and good condensing properties. It is most effective for precision machining, especially for pulse processing under pulse. It can also be used for cutting, welding and lithography. . The wavelength of the YAG solid-state laser cutting machine laser is not easily absorbed by non-metals, so it is impossible to cut non-metallic materials. Main advantages: It can cut aluminum plates, copper plates and most non-ferrous materials that can not be cut by other laser cutting machines. The purchase price of the machine is cheap, the maintenance is simple, and the quality of workers is not high.
Third, fiber laser cutting machine
The principle of the fiber laser cutting machine is that the laser beam is transmitted through the optical fiber, the flexible processing is good, the fault is small, the maintenance is convenient, and the speed is fast, so the fiber cutting machine has great advantages when cutting the thin metal plate. The fiber laser cutting machine has a wavelength of 1.06 um and is not easily absorbed by non-metals, so it cannot cut non-metallic materials. The photoelectric conversion rate of fiber laser is as high as 25% or more. The advantages of fiber laser in terms of electricity consumption and supporting cooling system are quite obvious. As an emerging laser technology, fiber laser cutting machines are currently gaining popularity in the market. Main advantages: high photoelectric conversion rate, low power consumption, one-time molding, saving the next process, saving labor, high cutting precision and high efficiency. It is the fastest laser cutting machine for cutting thin plates in these three machines, with small slits. The spot quality is good and can be used for high precision cutting.
