Hey there! As a supplier of mixed laser cutting machines, I often get asked about the differences between CO2 and fiber – based mixed laser cutting machines. So, let’s dive right in and break it down. Mixed Laser Cutting Machine
How They Work
First off, let’s talk about how these two types of machines operate. CO2 laser cutting machines use a gas mixture, mainly carbon dioxide, nitrogen, and helium, to generate laser light. An electric current is passed through the gas mixture, exciting the CO2 molecules. When these excited molecules return to their normal state, they release photons, which are then amplified to form a powerful laser beam. This beam is then directed onto the material to be cut.
On the other hand, fiber – based laser cutting machines use optical fibers doped with rare – earth elements like ytterbium. A diode pump sends light into these fibers, and the rare – earth elements absorb the light energy. The energy is then converted into laser light within the fiber. The laser beam is then delivered to the cutting head through the fiber itself. This direct delivery system gives fiber lasers some unique advantages.
Cutting Performance
When it comes to cutting performance, there are some significant differences between CO2 and fiber – based machines.
Metal Cutting
Fiber – based lasers are the real champs when it comes to cutting metals. They have a much higher absorption rate in metals compared to CO2 lasers. That means they can cut through metals more quickly and with less power consumption. For thin metals, especially those less than 6mm thick, a fiber – based mixed laser cutting machine can cut at incredibly high speeds. These machines can also achieve very high – quality cuts with smooth edges and minimal dross (the waste material that forms during cutting).
CO2 lasers, however, are not as efficient in cutting metals. They have a lower absorption rate in metals, which means they need more power to make the same cut. This results in slower cutting speeds and higher energy consumption. Also, the cut quality on metals may not be as good as that of fiber lasers, with more chances of rough edges and dross.
Non – Metal Cutting
When it comes to non – metal materials like wood, acrylic, and leather, CO2 lasers shine. They have a better absorption rate in non – metals, allowing them to cut through these materials with ease. The beam of a CO2 laser can be focused to a relatively large spot size, which is ideal for non – metal cutting. It can vaporize the material smoothly, creating clean cuts.
Fiber lasers, on the other hand, are less suitable for non – metal cutting. The high absorption rate in metals means that non – metals don’t absorb the fiber laser beam as well. This can lead to uneven cuts or even failed attempts at cutting non – metal materials.
Maintenance
Maintenance is another important factor to consider when choosing between a CO2 and a fiber – based mixed laser cutting machine.
CO2 lasers require more maintenance. The gas mixture in the laser tube needs to be replenished regularly. The mirrors and lenses in the beam delivery system also need to be cleaned and aligned frequently. If the alignment is off, the laser beam may not be focused correctly, leading to poor cut quality. And replacing the laser tube can be a costly and time – consuming process.
Fiber lasers, on the other hand, are much more maintenance – friendly. They have a solid – state design, which means there are fewer moving parts. The fiber optic cable that delivers the laser beam is highly reliable and doesn’t require much maintenance. There are no gas mixtures to replenish or mirrors to align. This reduces the overall maintenance cost and downtime of the machine.
Cost
Cost is always a big consideration when buying a laser cutting machine.
Initial Purchase Cost
In general, fiber – based mixed laser cutting machines have a higher initial purchase cost compared to CO2 machines. The technology behind fiber lasers is more advanced, and the components are more expensive. However, the price gap has been narrowing in recent years as fiber laser technology becomes more widespread.
Operating Cost
When it comes to operating costs, fiber lasers have the upper hand. As we mentioned earlier, they consume less power when cutting metals, which means lower electricity bills. And with less maintenance required, the long – term operating costs are also lower.
CO2 lasers, while cheaper to buy initially, can have higher operating costs. They consume more power, and the cost of gas replenishment and frequent maintenance adds up over time.
Applications
The differences in cutting performance and other characteristics make these two types of machines suitable for different applications.
Fiber – based mixed laser cutting machines are widely used in industries that require high – speed and high – quality metal cutting, such as the automotive, aerospace, and electronics industries. They are great for precision cutting of metal parts, like engine components, circuit boards, and metal casings.
CO2 lasers are commonly used in industries that work with non – metal materials, such as the furniture, signage, and leather industries. They are perfect for cutting and engraving wood, acrylic, and leather to create decorative items, signage boards, and leather products.
So, as you can see, both CO2 and fiber – based mixed laser cutting machines have their own strengths and weaknesses. Choosing the right one depends on your specific cutting needs, budget, and the type of materials you work with. If you’re mainly cutting metals and need high – speed, high – quality cuts, a fiber – based machine might be the way to go. But if you work a lot with non – metal materials, a CO2 laser cutting machine could be a better fit.
