Types of laser cutting machines and advantages of laser cutting
There are several types of laser cutting technology, including CO2 laser cutting machine, fiber laser cutting machine and YAG laser cutting machine . The laser as a core component of the laser cutting machine, the mainstream laser on the cutting market today also has three distinctions, including fiber lasers, CO2 lasers and YAG lasers, the three in the cutting material there are differences, such as: the quality of processing materials, speed, energy consumption and so on.
For example, CO2 laser cutting machine is ideal for cutting thick materials, including steel and aluminum; But the cuts it produces are less precise and more cost-effective than fiber laser cutting machine . Fiber laser cutting machine is most suitable for cutting high precision, thin materials, such as stainless steel, copper, brass and so on.
Each technology has its own advantages and disadvantages, depending on the application scenario and how it is applied, although the type is different, the working process of the laser cutting machine is relatively the same. Based on years of experience, Genuo has analyzed the advantages and disadvantages of the three types of laser cutting machines currently on the market to help users distinguish how to choose the right laser cutting machine.
一, fiber laser cutting machine
Advantages:
Fiber laser cutting machine using fiber laser transmission through fiber, can easily achieve flexible processing, and in the radio and television conversion rate is higher, can reach more than 25%, the consumption of electric energy is small. When cutting thin sheets below 12 mm, it is the fastest and best cutting quality of all cutting machines in the market. It adopts optical fiber transmission, small beam diameter, small cutting gap, good spot quality, can be used for fine cutting processing.
Cons:
Most of the core technologies of fiber laser cutting machine are in the hands of mature foreign companies, so some parts of the fiber laser cutting machine produced are imported, which increases the cost of cutting equipment. Generally speaking, the price of fiber laser cutting machines is more expensive, in addition, the cutting speed is also slower in cutting thick materials and cutting high-reflective materials.
Market positioning:
Fiber laser cutting machine has an absolute advantage in the thin sheet cutting market below 12 mm, especially in the processing of thin sheets with high precision, the advantages of fiber laser cutting machine are more obvious. Therefore, the market of fiber laser cutting machine is positioned in the precision processing of thin plate cutting and requires high efficiency manufacturers. In addition, with the technological breakthrough of high-power fiber lasers, the market share of fiber laser cutting machines is also getting higher and higher, which is very worthy of the attention of major manufacturers.
二,YAG laser cutting machine
Advantages:
YAG laser cutting machine can cut high-reflective materials, such as aluminum, copper and many other non-ferrous metal materials that laser cutting machines can not cut. At present, all mature manufacturers have mastered the key technology of YAG laser cutting machine, so the cost of procurement is low, at the same time, YAG laser cutting machine is convenient to operate and simple to maintain.
Cons:
Only thin sheet materials below 8 mm can be cut, and the cutting speed is slow and the efficiency is relatively low.
Market positioning:
For small and medium-sized enterprises do not have high requirements of 8mm material cutting, can be used in sheet metal manufacturing, advertising industry, electronics industry, hardware industry, kitchenware industry and so on. At present, the YAG laser cutting machine on the market has slowly replaced the traditional line cutting machine, water cutting, CNC cutting, flame cutting and other processing modes.
三,CO2 laser cutting machine
Advantages:
High power, CO2 laser cutting machine can cut 25 mm stainless steel, carbon steel and other materials. The cutting thickness of non-metallic materials such as acrylic, wood and PVC can reach 60 mm. In addition, it can also cut 4 mm aluminum sheet of highly reflective material. CO2 laser cutting machine uses continuous laser, the cutting surface is smooth and the cutting quality is good.
Cons:
CO2 cost is high, high-power CO2 laser cutting machines have reached more than 2 million, and the cost of maintenance is high. The photoelectric conversion rate in the use process is only 10%, resulting in high energy consumption, inconvenient maintenance, and high operational requirements for personnel.
Market positioning:
CO2 laser cutting machine is mainly located in the thick plate cutting, generally 6 to 25 mm high-power laser cutting machine. Nowadays, technology continues to break through, especially the technological development of fiber laser cutting machine has caused a relatively large impact on CO2 laser cutting machine, and the market compression is more severe, of course, the high-power laser cutting machine on the market is still dominated by CO2 laser cutting machine.
With the application of laser technology more and more mature, the application of laser cutting machine more and more widely, compared with the traditional cutting mode, laser cutting machine cutting surface quality is better, faster, relatively low cost, laser cutting machine will be the mainstream trend of the future cutting market.
Discussion: What is the difference between fiber laser cutting machine and CO2 laser cutting machine?
In the current metal processing industry, laser cutting machine has become a trend, and laser cutting is refined according to its different working methods. In recent years, fiber laser cutting has gradually replaced CO2 laser cutting machine in the metal processing industry, and has become one of the most important cutting means in the metal processing industry. So what are the differences and advantages between fiber laser cutting machine and CO2 laser cutting machine ?
1. Different luminous media
CO2 laser cutting machine: The gas is the medium that generates the laser beam and transmits the beam through the mirror.
Fiber laser cutting machine: The laser is transmitted through a diode and fiber optic cable, multiple diodes are pumped to produce a laser beam, and then transmitted through the fiber cable to the laser cutting head, rather than transmitting the beam through the mirror.
2. The appearance of fiber laser cutting machine is more compact
Due to the difference in laser transmission structure, the same power fiber laser cutting machine is more compact than the CO2 laser cutting machine, which saves the space of the workshop and is more suitable for old warehouses or small warehouse applications.
3. The electro-optical conversion efficiency of fiber laser cutting machine is high
Fiber laser cutting machine uses a complete solid-state digital module and a single fiber laser design, electro-optical conversion efficiency is higher than carbon dioxide laser cutting, CO2 laser cutting machine the actual total utilization of the power supply is about 8%~10%, the total utilization of fiber laser cutting machine is about 25%~30%, The total energy consumption of the fiber laser cutting system is 3 to 5 times lower than the total energy consumption of the carbon dioxide cutting system, increasing by more than 86%.
4. Fiber laser cutting machine has better processing effect
The fiber laser has the characteristics of short wavelength, which improves the absorption of the cutting material to the beam and makes the cutting of non-conductive materials such as brass possible. When the thickness of the cutting material reaches 6mm, the cutting speed of the 1500W fiber laser cutting machine is equivalent to that of the 3000W carbon dioxide laser cutting machine.
5. The maintenance cost of fiber laser cutting machine is low
CO2 laser cutting machine uses gas as a light-emitting medium. Due to the purity of the CO2 gas, the cavity will be contaminated and will need to be cleaned regularly. At the same time, the mirror of the CO2 laser cutting machine needs to be maintained and calibrated, so the daily maintenance workload is greater. A kilowatt CO2 laser cutting machine costs at least $20,000 per year. Therefore, from the perspective of other costs or environmental protection, fiber laser cutting is more environmentally friendly and convenient in the daily maintenance of equipment.
