Classification of metal and non-metal laser cutting machines

The principle of CO2 laser cutting machine is to use the transition between the vibration and rotational energy levels of carbon dioxide molecules to generate laser light. It is a very common machine in our daily life, which is usually used to cut non-metallic materials in our life. But then we have mixed laser cutting machines that can be used for both cutting metal and non-metal materials. What does the difference between the two machines bring to our industry?
The world's first CO2 laser cutting machine was born in the 1970s. For more than 30 years, due to the expansion of application fields, CO2 laser cutting machines have been continuously improved, and many international and domestic companies have been engaged in the production of various CO2 laser cutting machines to meet the market demand, including two-dimensional flat cutting machines, three-dimensional space curve cutting machines, tube cutting machines, etc. According to the 2000 annual report of "Industrial Laser Solution", an authoritative magazine on laser industry applications in the United States, the total number of laser cutting systems sold worldwide in 1999 (mainly CO2 laser cutting systems) was 3325 units, with a total of 1.174 billion dollars. Although the development trend of laser cutting is fast, but the application level compared with the developed countries, the gap is large. By 2003, the total number of CO2 laser cutting systems used in industrial production in China had reached about 500 units, accounting for about 1.5% of the total number of systems in operation worldwide.
CO2 laser cutting machine is one of the main products of our company. Combined with on-site production operation and give full play to motion control performance and laser processing effect, the unique interactive design allows free switching between single and double laser heads, offline work, uniform and consistent cutting effect, doubling the processing efficiency, making the goal of cost saving to provide output within reach. CO2 laser cutter is mainly through the motor and belt or screw drive, drive the laser head position change to achieve the laser cutting function.

CO2 laser cutting machine generally rely on laser power driven laser tube light, through the refraction of several reflectors, so that the light transmission to the laser head, and then the laser head installed by the focusing mirror will converge the light into a point. This point can reach a very high temperature, so that the material instantly sublimated into gas, sucked away by a fan, so as to achieve the purpose of cutting. General laser cutting machine using the laser tube filled with the main gas is CO2, so this laser tube becomes a CO2 laser tube, and the use of this laser tube laser cutting machine called CO2 laser cutting machine.
Co2 laser machine equipment processing a wide range of materials, cutting edge smooth burr-free, no polishing, no dust and chips, no noise, high efficiency, less waste, is the ideal choice for professional engraving and cutting users.

But only cutting non-metals cannot meet the needs of more customers. In the past, we usually choose fiber laser cutting machine to cut metals, but fiber laser cutters are expensive and cannot meet the needs of customers with low budgets. The co2 mixed laser cutting machine helped us solve this problem. For some customers who cut thin metal and non-metal materials and have a low budget, the laser mixed cutting machine has become the best choice for them.
The shape of metal and non-metal laser cutting machine is not much different from ordinary CO2 laser cutting machines, but the control of the main board is different. In addition, mixed laser cutting machine cutting metal when you generally have to add oxygen as an auxiliary gas.

The co2 mixed laser cutting machine is not as specialized as the fiber metal laser cutting machine. Fiber laser cutting machine have the power to cut very thick metals, but CO2 mixed laser cutters tend to cut thinner metals. For thin metals, the co2 mixed laser cutting machine is the most cost-effective option. Then what is the difference between the two for what we think of everyday as professional metal cutting machines fiber laser cutting machines?
In CO2 laser cutting technology, CO2 gas is the medium for generating the laser beam, compared to laser equipment construction. However, fiber lasers work with diodes and fiber optic cables for transmission. Instead of transmitting the beam through a reflector, the fiber laser system generates the laser beam by pumping multiple diodes and then transmits it through a flexible fiber optic cable to the laser cutting head. This has a number of advantages. Unlike gas laser technology where the reflector must be set at a certain distance, fiber laser technology has no range limitation. Likewise, the ability to bend the fiber makes the system more compact when compared to a gas cutting system of the same power.
The most important and meaningful advantage of fiber cutting technology should be its energy efficiency. With the fiber laser's complete solid-state digital module, a single design, fiber laser cutting systems have a higher electro-optical conversion efficiency than CO2 laser cutting. For the individual power supply units of a CO2 laser cutting system, the actual typical utilization rate is about 8% to 10%. For fiber laser cutting systems, users can expect higher power efficiencies in the range of 25% to 30%. In other words, the overall energy consumption of a fiber laser cutting system is much less than that of CO2 machine.
In terms of cutting performance, the fiber laser has a short wavelength, which improves the absorption of the beam by the material being cut, and allows for cutting materials such as brass and copper, as well as non-conductive materials. The more focused beam produces a smaller focal point and deeper depth of focus, which allows the fiber laser cutting machine to cut thinner materials quickly and medium-thick materials more efficiently.
Fiber laser cutting machine
After reading today's explanation, do you have a deeper knowledge and understanding of CO2 laser cutting machine, CO2 mixed laser cutting machine and fiber laser cutting machine? In production life, we often see many items made by these machines. Seemingly esoteric things are actually inseparable from our lives.
