What types of laser cutting machines are there?

Laser cutting machine, flame cutting machine laserpecker 2 pro, plasma cutting machine, water jet and so on.

Laser cutting machine efficiency, cutting precision is the highest, cutting thickness is generally smaller. The plasma cutting is also very fast and has a certain slope on the cutting surface. The flame cutting machine is suitable for carbon steel material with large thickness laserpecker 1.

After 20 years of development, according to the different laser generators laser cutter, the laser cutting machines on the market can be roughly divided into three types: CO2 laser cutting machine, YAG (solid state) laser cutting machine and fiber laser cutting machine. Here Xiao Xin will briefly introduce the characteristics of three kinds of laser cutting machines:

The first type: CO2 laser cutting machine.

CO2 laser cutting machine can be stable cutting carbon steel, stainless steel, 8 mm below. Aluminum alloy. The wavelength of CO2 laser is 10,6 microns, easy to be absorbed by non-metal. It can cut wood, acrylic, polypropylene, plexiglass and other non-metallic materials, and CO2 laser photoelectric conversion rate is only about 10% . The CO2 laser cutting machine is provided with an oxygen, Compressed air or inert gas N2 nozzle at the beam outlet to improve cutting speed and cut smoothness. In order to improve the stability and lifetime of power supply, the discharge stability of high power CO2 laser was studied. According to the International Safety Standard, the danger level of the laser is divided into 4 levels, and the CO2 laser is the lowest dangerous level of the laser.

Main advantages: high power, generally between-,can cut full-size stainless steel, carbon steel and other conventional materials within 25mm, and can also cut aluminum plates, acrylic plates, wood plates and PVC plates within 4mm, with very fast cutting speed. In addition, because CO2 laser outputs continuous laser, it is the smoothest and best cutting section among the three laser cutting machines.

Main market positioning: 6-25mm plate cutting, mainly for large and medium-sized enterprises and some pure processing laser cutting processing enterprises. In recent years, due to the great impact of fiber laser cutting machine, the market is shrinking significantly.

The second type: YAG (solid state) laser cutting machine

YAG solid laser cutting machine has the advantages of low cost, good stability, but the energy efficiency is generally less than 3% , the output power of most of the current products are as follows, because of the output power is small, mainly used for punching, spot welding and sheet cutting. Its green laser beam can be applied in the case of pulses or continuous waves. Short wavelength, good concentration of light. Suitable for precision machining, especially under the pulse hole processing. This is the most efficient. It can also be used for cutting, welding and lithography. YAG solid laser cutting machine is not easy to be non-metallic absorption of laser wavelength, can not cut non-metallic materials, YAG solid laser cutting machine need to solve the problem of improving power stability and life, namely, the development of large-capacity, long-life optical pump excitation light source, such as the use of semiconductor optical pump, which can greatly improve energy efficiency.

Main advantages: it can cut aluminum, copper and most non-ferrous metal materials that other laser cutting machines can't cut. This kind of machine is cheap, low in utilization and easy to maintain. Most of the key technologies have been mastered by domestic enterprises. The price of accessories and maintenance costs are low, the machine operation and maintenance are simple, and the quality of workers is not high.

The main market positioning: 8mm cutting, mainly for self-use small and medium-sized enterprises and most users in sheet metal manufacturing, home appliances manufacturing, kitchenware manufacturing, decoration, advertising and other processing requirements of the industry, gradually replace the wire cutting, CNC punching, water cutting, low-power plasma and other traditional processing equipment

The third type: fiber laser cutting machine

Optical fiber laser cutting machine, because it can be transmitted through optical fiber, has unprecedented flexibility, fewer fault points, easy maintenance and extremely high speed, so it has great advantages when cutting thin plates below 4mm, but when cutting thick plates, the laser quality is poor due to the solid wavelength. The laser wavelength of fiber laser cutting machine is 1, which is not easily absorbed by nonmetal, so it can't cut nonmetal materials. The photoelectric conversion rate of fiber laser is as high as 25%. In terms of power consumption and supporting cooling system, fiber laser has obvious advantages. According to international safety standards, the laser hazard level is divided into four levels. Fiber lasers are the most dangerous because of their short wavelength and harmful to eyes. For safety reasons, fiber laser processing needs a completely closed environment. As a new laser technology, fiber laser cutting machine is far less popular than CO2 laser cutting machine.

Main advantages: high photoelectric conversion rate, low power consumption, can cut stainless steel and carbon steel plate within the fine cutting, the main market positioning of the following cutting, especially high-precision thin plate processing, main needle
