Fiber Laser: An Economical & Effective Choice for A Perfect Edge

Fiber Laser An Economical Effective Choice
for A Perfect Edge

In the laser cutting, there are two main types of
lasers used in producing exceptional machinery
parts. CO2 lasers and fiber lasers. While CO2
lasers have the advantage of producing superior
edge quality, Fiber lasers are rising as
innovative

cutters in the industry. They are beneficial in
metal cutting due to their non-reflecting beam.
They cut quicker than their alternatives. One
of the major benefits of using fiber lasers is
the clean, oxide-free edge you get as an end
result. You can obtain it with nitrogen assist
gas. As there will be no oxidation, it improves
the downstream processes such as welding and
powder coating which in turn helps achieve better
adhesion and weldability. You can further
improve Fiber Laser's cut edge by making optimal
changes in the assist gases and nozzle
technologies. Here is how to start! Nitrogen
Purity Purity levels play a major role in the
quality of edge and other parts. If you want to
buy new ones, try searching for Amada Parts or
Fanuc Parts online for quality products. If you
know and understand what kind of expectations to
set from purity levels, it can help achieve the
desired quality for any part and other end
goals. If you are working for industries such as
medical and food-grade equipment which require a
bright silver finish, then you need to set the
purity levels to 99.9 percent.

If your targeted market is agricultural
implements and powder coat adhesion in which
your main focus areas include producing parts
per day, then a lower nitrogen purity level
between 98 to 99 percent will suffice the
requirement. It is important to understand what
you need in terms of level. This helps in sizing
your nitrogen generator properly, at the
beginning itself, to avoid edge quality glitches
which later affects the overall performance.
Moreover, using quality laser parts like Amada
parts would also benefit in the longer run. You
can also search for Fanuc parts online which fall
into the same quality parts category. Nitrogen
Consumption and Costs While operating any laser
cutting machine, be it fiber or CO2, the
consumption of nitrogen is always high. Several
factors cause this issue. With the fibers
upgraded technology, you have higher wattage
ratings available which can easily process most
of the materials. It might have been possible
that your CO2 laser had a limitation in cutting
mild steel with nitrogen assist gas at
3/16-inch-thick, or 7-gauge material. For
example, A 4-kilowatt CO2 laser may have used
1700 SCFH (standard cubic feet per hour) to cut
3/16-in-thick or 7-ga. mild steel. And to cut
?in-thick material, the gas consumption will
double to 3,400 SCFH.

And with the Fibers technology, this limitation
will no longer be a limitation as it can help
expand the mild steel nitrogen procession
range. Nitrogen Consumption Cut
Edge Nitrogen-generation systems reduce the cost
of nitrogen and eliminate gas supply contracts.
If you purchase your own nitrogen-generation
system, it becomes easier for you to take
advantage of the capital equipment depreciation
which accelerates your ROI. You can generate
nitrogen by separating air into argon, oxygen,
nitrogen, and CO2. It might come as a surprise,
but the air we breathe contains only 21 of
oxygen, a whopping 78 of nitrogen, 0.9 argon
and some traces of Carbon dioxide other
gases. Here are the most commonly used gas
separation systems Pressure swing adsorption,
cryogenic fractional distillation (used to
separate liquid air), and membranes. 1.
Adsorption system is the best method when higher
delivery pressures and flow rates are a
necessity. This system uses a carbon molecular
sieve to absorb the oxygen molecules and produce
the desired nitrogen assist gas. It can deliver
higher gas pressure as well as higher SCFH flow
rates.

• In the process of cryogenic fractional
  distillation of liquid air, the separation of
  gases takes place by cooling the air until it
  liquefies. These are the bulk tank systems that
  provide assist gases to the lasers and can
  deliver high purity levels. But these are
  usually energy-intensive.
• The membrane system contains hollow fiber
  membranes for creating a mechanical process to
  separate the air. It is possible because of the
  molecular-sized variance of the nitrogen and
  oxygen molecules. The structure of the membrane
  polymer allows the fast-moving water vapor and
  oxygen molecules to distribute through the
  membrane. And then captures the nitrogen as the
  product gas.
• Generating your own nitrogen may accelerate your
  ROI. In most cases, you can achieve the ROI in
  less than two years. For the manufacturing units
  using multiple machines or running multiple
  shifts, achieving such ROI will be in less than 2
  years. And once the company achieves ROI, they
  will be saving a lot on delivery fees, equipment
  rental fees, etc.
• Not only an economical choice but for better
  results also, Fiber Lasers have it all. Also,
  using Amada Parts for your machines would
  maximize its productivity. There are cost
  advantages, superior quality and are safer than
  CO2 lasers.
