High-Powered Fiber Lasers: Are they Right for You?

High-Powered Fiber Lasers Are they Right for
You?

For processing laser cuts with 0.25-inch to 4-kW
laser, it can be a hurdle-less task for
fabricators. Now when it comes to 12-kW or 15kW,
they need high-powered fiber lasers. And there
are choices available in the market, but if you
as a fabricator want to focus on thick metal
cutting, only high-powered lasers are not the
right choice. The 15-kW machines can do more
tasks than cutting the thick material. Overall,
the major motive behind this laser technology is
about decreasing process time in laser cutting.
Lets explore what these fiber lasers can do for
a fabrication shop.

A Little Throwback to History During the
mid-2000s, high-powered laser cutting machines
were a necessary tool for quick and efficient
armor kits for US troop vehicles. After a few
years with the debut of fiber laser technology,
these giant machines were not in the trend
anymore. Why Fiber Laser Technology is a
Hero Fiber lasers produce a beam wavelength which
is about 10 times shorter than the 10-micron
beam wavelength with a CO2 resonator. It
produces a higher power density which you add to
the higher absorption rate will create a great
cutting speed. This cutting speed outpaces that
of a CO2 laser in less than 0.25 in. It becomes
easy for manufacturers to increase the power of
these machine tools with the additional
laser-producing modules, Amada laser parts, and
Prima parts. That is the reason for the sudden
surge in wattages. In fact, these systems can
exceed 100KW in some instances. Beam delivery
systems cannot handle the power of 100-KW
systems on their shop floors. Hence, each laser
cutting system manufacturer is looking to
produce a reliable cutting head which can
deliver the fiber laser beam for an extended
amount of time.

• Recently, these machine tool developers are
  stepping into the production of cutting head
  optics which can modulate the beam size during
  cutting. Its development propelled fiber laser
  cutting machines from being a tool just for
  cutting thin sheet metal. When the cutting
  material gets thick, you need a wider beam to
  create kerf to remove the molten metal.
• It is important for a company to look at the
  typical thickness range which makes up 80
  percent of its work. Also, to make sure that
  your lasers are working fine, you need to install
  Amada laser parts and prima parts.
• Here are the general rules to cut common metal
  such as steel, stainless steel, or aluminum with
  nitrogen
• Up to 9 gauge6 to 8 kW
• 0.25 to 0.75 in.8 to 10 kW
• Over 0.75 in.8 to 15 kW
• Utilize the Material Exchange
• The processing time on a fiber laser cutting
  machine is tied with the systems ability to
  load sheets, unload cut parts, and skeletons. A
  fabricator does not gain any cycle time advantage
  if it has to wait for several times for the
  material movement. A lot of pallet changers are
  designed with CO2 lasers. It cuts slower rates
  compared to fiber lasers. They use hydraulics and
  can take 35 to 50 seconds to exchange a sheet.

The modern pallet changers rely on servo-driven
technology. Here the automation is critical.
When it comes to selecting pallet changer
technology, fabricators should select one which
can handle the thickest material they process. Is
High-powered Laser the right choice for you? No,
if your shops laser cutting workload is not
expecting continuous growth. If it consumes only
half of work shift, paying for a powerful laser
to reduce the workload to a quarter of a shift
wont deliver a good return on investment. If
metal fabricators are maximizing their current
laser cutting capacity, adding another shift,
they can look at high-powered lasers. It is true
when they use older laser technology. They can
invest in a fast and efficient laser to reduce
the number of laser operators needed. Fiber
laser cutting machines will grow in power if the
cutting head and material handling can
complement the power. You as a fabricator can
take advantage of the power if you can feed
these cutting machines for proper maintenance.
