In the laser cutting machine market, there are two kinds of machines that are very popular. One is fiber laser cutting machine and the other is CO2 laser cutting machine.CO2 laser cutting machine occupies the mainstream position in the traditional sense, while fiber cutting machine has started to take the market by storm in recent years and become more and more popular. However, do you know the difference between these two machines? Which machines can meet our needs, and how to choose?
Laser cutting machine
1. First of all, let's understand the working principle of these two laser cutting machines
The working principle of fiber laser cutting machine: fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as the light source. Fiber laser cutting machine is a new type of fiber laser, which can output a high energy density laser beam, and will be gathered on the surface of the workpiece, so that the workpiece is instantly melted and vaporized by the ultra-fine focus spot irradiation area, through the CNC mechanical system to move the spot irradiation position to achieve automatic cutting, fast and high precision.
The working principle of CO2 laser cutting machine is that the laser power supply drives the laser tube to emit light, refracted by a number of reflective mirrors, so that the light is transmitted to the laser head, which is then installed on the laser head of the focusing mirror laser head will converge the light into a point that can reach a very high temperature, so that the material is instantly sublimated into gas, which is sucked away by the extractor fan, thus achieving the purpose of cutting.
2. The working principle of the two laser cutting machine determines the application areas in which they excel
CO2 laser wavelength of 10.6um, fiber laser wavelength of 1.06um. the former is more easily absorbed by non-metals, can be high-quality cutting wood, acrylic, PP, organic glass and other non-metallic materials. Fiber laser cutting machine can only cut metal, can not cut fabric, leather, stone and other non-metals, the reason is simple, fiber laser cutting machine wavelength range is not in the absorption range of the above materials, or absorption is not appropriate to achieve the desired cutting effect, the current advantages of fiber laser cutting machine in the application of non-metal cutting is not very obvious.
3. Then we should choose which laser cutting machine?
Of course, we have to choose according to the material and the area where the machine is applied.
Fiber laser cutting machine is widely used in electronics, electrical appliances, mechanical hardware, new energy equipment, solar energy, LED, automotive and other industries. It is good at processing common metal products in daily life, such as advertising metal letters, kitchenware, environmental protection equipment, etc. Widely used in stainless steel, carbon steel, alloy steel, copper, brass, silicon steel, galvanized steel, nickel-titanium alloy, chromium-nickel-iron alloy, titanium alloy, etc.
CO2 laser cutting machine, capable of engraving and cutting various non-metals, such as acrylic, marble, wood, density board, plywood, textile, leather, glass, paper, etc. It is widely used in many industries such as handicrafts and gifts, souvenirs, Chinese paper cutting, billboards, garments, furniture, etc.
So what about cutting both metal and non-metal materials?
Buying two machines is certainly an option, but two-in-one machines are more advantageous in terms of cost and space occupation. Jinan Youben Machinery Co., Ltd. produces two types of machines that can cut both metal and non-metal.
1. One type is hybrid laser cutting machine. This machine adopts CO2 laser as laser source, and adds laser head that can cut metal to the standard CO2 laser machine. This hybrid metal laser cutting machine can be widely used to cut non-metal materials and metal plates with smooth cutting edge and no burr.
The machine has fast processing speed, high precision and high efficiency. The running speed is fast, the laser energy is adjustable in real time and the operation is very easy.
2. The other model is a hybrid model, which combines two laser sources, fiber laser generator and CO2 laser tube, on one machine for cutting. Two systems are used to control the fiber laser cutting head and CO2 laser cutting head respectively to achieve metal and non-metal cutting.
CO2 & fiber two-in-one metal and non-metal laser cutting machine adopts double gantry structure, which has the advantage that it can be equipped with two independent control systems to control fiber laser and CO2 laser respectively.
So with two heads, metal materials can be processed with fiber laser head and non-metal materials can be processed with CO2 laser cutting head. One machine has more functions, which is more cost-effective than buying two machines separately.
