The laser cutting machine has performed well in recent years. Its laser cutting processing, whether in appearance, efficiency and stability, far surpasses traditional cutting processing. With the seemingly simple laser cutting, what is its cutting principle? Let's take a look together below.
The principle of cnc fiber laser cutting machine: fiber laser is to dope the pump material into the fiber. After the laser of a specific wavelength emitted by the semiconductor laser is combined, the fiber will generate laser light and focus on the surface of the workpiece, so that the workpiece is The area irradiated by the spot is melted and vaporized instantaneously, and the spot irradiation position is moved by the computer-controlled numerical control mechanical system to realize automatic drilling. It is a high-tech equipment integrating laser technology, numerical control technology, and precision machinery technology.
Materials that can be processed by the sheet metal laser cutting machine: It can cut a variety of metal plates and pipes, mainly suitable for stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, galvanized steel, pickling Cutting of plates, copper, silver, gold, qin and other metal plates and pipes.
The scope of application of stainless steel laser cutting machine price: metal sheet processing, advertising sign production, high and low voltage electrical cabinet production, mechanical parts, kitchenware, automobiles, machinery, metal crafts, saw blades, electrical parts, glasses industry, spring sheets, circuit boards , Electric kettles, medical microelectronics, hardware, knife measuring tools and other industries.
Fiber laser cutting machine has the following characteristics:
(1) Use cutting-edge fiber lasers, with extremely high photoelectric conversion efficiency, stable performance, and service life of key components
Up to 100,000 hours;
(2) The laser generation process does not require gas, air-assisted cutting, optical fiber transmission, and no need to adjust the optical path;
(3) The laser is transmitted by optical fiber, no reflective lens is required, which can save a lot of maintenance costs;
(4) Compared with other medium laser equipment, fiber laser cutting machine has a smaller focus spot and higher working efficiency.
Better processing quality;
(5) Simple structure and small area;
(6) Capable of handling any harsh working environment, that is, it has high resistance to dust, vibration, impact, humidity and temperature
(7) High precision and fast speed, mainly for fast and precise cutting of metal plates below 4mm.
The processing advantages of fiber laser cutting machine are as follows:
(1) High precision, fast speed, narrow cutting seam, minimum heat-affected zone, smooth cutting surface without burrs;
(2) The stainless steel laser cutting machine price head does not touch the surface of the material and will not scratch the workpiece;
(3) The slit is the narrowest, the heat-affected zone is the smallest, the local deformation of the workpiece is small, and there is no mechanical deformation;
(4) Good processing flexibility, can process any graphics, and can also cut pipes and other profiles;
(5) It can cut any hardness materials such as steel plate, stainless steel, aluminum alloy plate, cemented carbide, etc. without deformation.
Laser cutting machines generally range from hundreds of thousands to millions. Generally, the price of 300W-500W fiber laser cutting machine is between 200,000 and 600,000; the price of 500W to -1000W fiber laser cutting machine is between 500,000 and 1.2 million; the price of 1000W-2000W laser cutting machine is between 1 million- It ranges from 1.5 million and may be higher. More than 2000W belongs to high-power laser cutting machine. Relatively speaking, there are fewer choices on the market, and there are many factors that affect the price of high-power laser cutting machine. The main influences include: laser type, laser cutting machine power, machine configuration, Brand and other factors.
First of all, the prices of large sheet metal laser cutting machine using different lasers are different. The basis for selection is the material of the cutting machine. There are three types of YAG lasers, CO2 lasers, and fiber lasers on the market. Among them, YAG laser cutting machine is used for punching, spot welding and cutting of thin plates. The energy efficiency is low and non-metallic materials cannot be cut. The CO2 laser cutting machine can cut thicker metal sheet materials and has a good cutting effect on non-metallic materials. The fiber laser cutting machine is mainly used to cut thin metal sheets within 20mm. Various lasers have advantages and disadvantages. When considering the price of a large laser cutting machine, the cost of use should also be considered: From the perspective of cost, YAG has high maintenance costs and CO2 lasers have good non-metal cutting effects, but the photoelectric conversion efficiency is low and maintenance costs are high. , Fiber lasers have low cost without consumables, but the range of cutting materials is small.
Then, the power directly affects the price of a large laser cutting machine, and the cutting power is directly related to the thickness of the cutting material. Take our commonly used stainless steel and carbon steel as an example. At present, the 1000W fiber laser cutting machine can cut carbon steel with a maximum thickness of 10mm and stainless steel with a maximum thickness of 5mm; 4500W laser cuts stainless steel with a maximum thickness of 20mm, but the quality of the cutting surface above 12mm is not guaranteed, and below 12mm Absolutely bright cut. The cutting capacity of 6000W will be better, but the price is also higher.
About the brand of large laser cutting machine. At present, large-scale laser cutting machine brands have blossomed everywhere, all over the country, but there is a mixture of fish and dragons, the quality of various equipment is uneven, and after-sales disputes are frequent. Large-scale laser cutting machines cost tens of millions and are expensive, and their quality and after-sales guarantee are very important. Therefore, do a good job of investigation when choosing a brand, and try to choose the manufacturer that has cooperated.
Finally, I have determined what kind of large-scale laser cutting machine needs how much power, and there are several intentional brands, and the approximate budget is already known. Finally, you can negotiate one by one, compare the parameters of large-scale laser cutting machine format, cutting speed, cutting accuracy, CNC system, etc., and buy the best.
