The difference between fiber laser cutting machine and early laser cutting is analyzed as follows:

YAG solid laser cutting machine (2009-2012).

It has swept the metalworking market, mainly for punching and spot welding and cutting thin plates. YAG solid laser cutting machine has the characteristics of low and good stability, but the energy efficiency is low, the output power of the products in 2009-2012 is mostly below 850W, due to the small output energy, it is mainly used for punching and spot welding and cutting of thin plates.

Main market positioning: cutting below 8mm, mainly for self-use small and medium-sized enterprises and most of the sheet metal manufacturing, home appliance manufacturing, kitchenware manufacturing, decoration, advertising and other industry users with low processing requirements, gradually replacing wire cutting, CNC punching, water cutting, low-power plasma and other traditional processing equipment.

Disc laser cutting machine (2015-2016).

The main advantage of disc laser cutting in the non-ferrous processing market: Disc lasers are a combination of the advantages of solid-state lasers and semiconductor lasers. The disc design guarantees excellent beam quality.

The use of a diode laser as a pump source unit ensures high photoelectric efficiency. With a power of up to 16,000 watts, the disc laser is characterized by the ability to cut thick materials such as brass and aluminum.

Main market positioning: cutting below 25mm, especially high-quality cutting of medium and heavy plates, mainly for external processing, or processing of non-ferrous metals more enterprises. The disadvantage is that the maintenance cost in the later stage is large, the service and technology have not yet been opened and popularized, and the cost is higher than that of optical fiber.

With the advent of fiber 4000w and above lasers, fiber laser cutting machines will eventually replace most of the market.

Fiber metal laser cutting machine (2012-2020).

The main advantages of high-power impact and low-power processing market, and finally popularization of major factories: high photoelectric conversion rate, low power consumption, can cut stainless steel plate within 20-30mm, carbon steel plate, is the fastest cutting speed in these three machines, small cutting seam, light spot, can be used for fine, stable and efficient cutting. 2012-2020 Main Market Positioning:

Manufacturing, sheet metal industry, agricultural machinery, municipal garden ......Wait a minute. After 2015, with the emergence of 4000W and above lasers, fiber laser cutting machines have replaced most of the CO2 high-power laser cutting, YAG laser cutting machines, disc laser cutting machines and other machines. Fiber laser cutting machine is developing towards more refined, industrialized, and deeply customized supporting development.

Wuhan Shuangcheng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating R&D, production and sales of professional laser complete sets of equipment, located in Hubei, the birthplace of lasers in China. Wuhan". We are committed to providing global users with a full range of solutions such as laser intelligent cutting equipment, welding equipment, and automated production lines.

At present, in the metal processing market, fiber laser cutting machine has gradually replaced CO2 laser cutting machine and traditional processing methods, and has become the mainstream equipment in sheet metal processing. What is the difference between fiber laser cutting machine and CO2 laser cutting machine, and what are the advantages?

1. The luminescent medium is different.

CO2 laser cutting machine, gas is the medium that produces the laser beam, which is transmitted through a mirror. Fiber lasers are transmitted through diodes and fiber optic cables, with multiple diodes pumped to generate a laser beam, which is then transmitted to the laser cutting head via a flexible fiber optic cable instead of a mirror.

2. The appearance of the fiber laser cutting machine is more compact.

Due to the different laser transmission structure, the fiber laser cutting machine with the same power in appearance and size is more compact than the CO2 laser cutting machine, thus saving plant space.

3. The conversion efficiency of fiber laser cutting electromechanical light is higher.

With a complete solid-state digital module and a single design, the fiber laser cutting machine has a higher wall-plug conversion efficiency than CO2 laser cutting. The actual general utilization rate of each power unit of the CO2 laser cutting machine is about 8% to 10%, while the value of the fiber laser cutting machine is about 25% to 30%, and the overall energy consumption of the fiber laser cutting system is about 3 to 5 times less than that of the carbon dioxide cutting system, so that the energy efficiency is improved to more than 86%.

4. The processing effect of fiber laser cutting machine is better.

Fiber lasers have short wavelengths, which improve the absorption of the beam by the cutting material and enable the cutting of materials such as brass and copper as well as non-conductive materials. When cutting materials up to 6mm thick, the cutting speed of the fiber laser cutting machine is equivalent to the cutting speed of a 3kw carbon dioxide laser cutting machine.

5. The maintenance cost of fiber laser cutting machine is lower.

CO2 laser cutting machine uses gas as the luminescent medium, due to the purity of CO2 gas, the resonator cavity will be polluted, which needs to be cleaned regularly, and the mirror needs to be maintained and calibrated, so the daily maintenance workload is greater. For a kilowatt-class CO2 laser cutter, this would cost at least $20,000 per year. In general, fiber laser cutting is more environmentally friendly and convenient in the daily maintenance of equipment.

What is the difference between a fiber laser cutting machine and a carbon dioxide laser cutting machine?

1. Equipment maintenance cost, the maintenance cost of carbon dioxide laser cutting machine is huge, not only the front mirror and tail mirror are expensive, but also the life of the turbine bearing is only 8000 hours, and the replacement cost is expensive. However, the fiber laser cutting machine is maintenance-free, basically no consumables, and can withstand the harsh working environment, with a high tolerance to dust, shock, humidity, and temperature.

2. Compared with the processing cost, the carbon dioxide laser cutting machine not only produces gas consumption during processing, but also the photoelectric conversion rate is only 8%-10%. The fiber laser cutting machine does not require any other consumption during processing, and its photoelectric conversion rate can reach 30%, which is more energy-saving and power-saving.

3. Compared with the technical aspect, the laser structure of the carbon dioxide laser cutting machine is complex, the maintenance cost is high, and the beam divergence is large in processing, which is not suitable for large-format processing. Although the cutting seam is relatively thin, it is very slow when processing thick plates. However, the laser characteristics of the fiber laser cutting machine are reflected in the miniaturization, intensification, high brightness and high conversion rate, in the processing of thin plates, the same power fiber laser cutting machine is 2-3 times higher than the cutting speed of carbon dioxide, and the cutting section is smooth.

It is said that the reason why the fiber laser cutting machine can quickly gain a foothold in the market and gradually replace the traditional cutting process is precisely because of its various advantages in technology, which provides the necessary process technology for the realization of product finishing.

Hanma Laser Xiaozeng will tell you the difference between fiber laser cutting machine vs early laser cutting The laser is transmitted to the focusing head through the optical fiber, and the flexible connection method is easy to match with the production line to achieve automatic work.

The ideal beam quality of the optical fiber greatly improves the cutting quality and work efficiency.

The extremely high stability and ultra-long pump diode life of fiber lasers determine that there is no need to adjust the current to adapt to the aging problem of xenon lamps like traditional lamp-pumped lasers, which greatly improves the stability of production and product consistency.

The photoelectric conversion efficiency of fiber laser is higher than 25, and the system consumes less power, is small in size, and occupies less space.

Compact structure, high system integration, few failures, simple and easy to use, no optical adjustment, low maintenance or even zero maintenance, truly achieve "landing light", plus anti-shock vibration, anti-dust, truly suitable for applications in the field of industrial processing.

The differences between carbon dioxide cutting machine and fiber laser are as follows:

CO2 laser cutting machine.

In the year 2000, there was a complete set of high-power laser cutting equipment, which can cut full-size stainless steel plates within 25 mm, carbon steel and other conventional materials, as well as inner aluminum plates and acrylic plates.

Because the CO2 laser beam is a continuous laser, it is the best cutting section effect in the laser cutting machine, but the main engine of the carbon dioxide laser cutting machine consumes too much power, and the laser is expensive to maintain and other insurmountable factors, in recent years, it has been greatly impacted by the fiber laser cutting machine, and the market has been obviously in a state of malaise.

Fiber metal laser cutting machine.

Fiber laser cutting machines transmit energy through a flexible and integrated optical fiber. Fiber laser cutting machines have a compact, all-solid-state, fiber-to-fiber design that does not require alignment or adjustment through any lenses or optics.

Compared to traditional laser cutting machines, fiber laser cutting machines are small and lightweight, which saves floor space, and since traditional laser cutting machines achieve precise collimation through lenses, they must be applied with great care; The structure of the fiber laser cutting machine is more stable, can be transported in various working environments, and is easier to transport.

Metal material suitable for fiber laser cutting machine:

1. Stainless steel:

Laser cutting is easier to cut stainless steel sheets. With the high-power YAG laser cutting system, the maximum thickness of stainless steel can be cut up to 4mm. The low-power YAG laser cutting system we developed can cut stainless steel up to 4mm thick.

2. Alloy steel:

Most alloy steels can be cut with a laser with good trimming quality. However, tool steels and hot die steels containing tungsten high will have erosion and sticky residue during laser cutting.

3. Carbon steel: The maximum thickness of the carbon steel plate that can be cut by the modern laser cutting system is close to 20mm, and the cutting gap of the thin plate can be narrow to about about it. Laser-cut mild steel has a very small heat-affected zone, and the cut is smooth, smooth, and has good verticality. For high-carbon steel, the laser cutting edge is better than that of low-carbon steel, but its heat-affected zone is larger.

The maximum cutting depth of our company's AHL series laser machine is 5mm

4. Aluminum and alloys

Aluminum cutting is a kind of melting cutting, and the molten matter in the cutting area is blown away by auxiliary gas, and a better cut quality can be obtained. Currently, the maximum thickness of cutting aluminum sheet is:

5. Other metal materials:

Copper is not suitable for laser cutting, and it is cut very thin.

6. Non-metallic materials:

Lasers can cut organic materials such as plastics (polymers), rubber, wood, paper products, leather, and natural and synthetic fabrics; At the same time, it can also cut inorganic materials such as quartz and ceramics, as well as composite materials such as new lightweight reinforced fiber polymers.
