The fiber lase sale como ganador en la comparativa de las 7 mejores tecnologías industriales para cortar metal for many different factors. A few years ago, lasers could only be applied with CO2 or Nd:YAG, but today they have been largely overtaken by the fibre laser.
We will now go through the advantages of fibre laser cutting when machining and cutting metal sheets and tubes. If you are in a situation where you are looking to invest in a fibre laser machine, we recommend that you contact us and even let us calculate for you what the production price per unit will be in your company to guide you on how you are going to amortise the machine.
Whether you want to renew your old machinery, stop subcontracting or expand production, at Perez Camps milling machines we have what you need.
Those of us who have experience in the industry know that the power consumption of such machines is not a minor expense, so this needs to be taken into account.
Nd:YAG and CO2 lasers have a low efficiency (between 3% and 5%) and generate large amounts of heat, so they require a water cooling system, which in turn also requires large amounts of energy.
On the other hand, fibre lasers have a performance 4 or 5 times higher , which, apart from consuming much less electrical energy, results in minimal heat generation, making it possible for powers of up to 260W not to require liquid cooling (only forced air) or for laser powers of the order of 500W to require less than 800W in terms of cooling.
In conclusion, to generate 500W of laser with a fibre system, between resonator and cooler we will need between 3 and 4KW of energy, while in a CO2 system we will need between 14 and 18KW of energy. Working 8 hours a day, this translates into about 30 Megawatts of energy savings per year..
Unlike the CO2 laser, there are no mirrors, as the fibre arrives directly into a sealed module where the focal lens is installed. It is also important to note that the resonator does not require gas mixing or any kind of start-up procedure as in axial flow lasers. To start working with a fibre laser, it is only necessary to activate the power switch.
This is not only beneficial as a matter of time, but also makes maintenance much easier and extends the lifetime of the machine. The estimated lifetime of a fibre laser machine is around 50,000-100,000 hours, which ensures a few years of uninterrupted production.
As we explained extensively in this article on how avoid burrs in metal laser cutting, Pérez Camps fibre laser machines are programmed to automatically control several laser parameters, such as power and beam profile.
In addition, to avoid burring it will be necessary to adjust these three parameters: gas pressure, focal distance and cutting speed. They are programmed automatically but it is advisable to adjust them for better cutting quality.
As for the gas, whether it is nitrogen or oxygen, we must make sure that it is as pure as possible. Oxygen must have a minimum purity of 99.95% and nitrogen 99.999%.
Laser cutting, which is used to cut steel, aluminium, brass and copper, is the the fastest and most accurate system compared to other cutting systems. We have also seen that it consumes much less energy than other options, has a long service life and avoids burrs.
