Basics of Laser Cutting Machines
The evolution of small laser beam light toys into
huge machines serving industrial demands today,
laser technology has come a long way. However,
apart from industrial demands like cutting and
pressing metal sheets, this technology is much
more than that. Lets read the basics with little
but important details involved behind Laser
machines.

• What is Laser?
• LASER is an acronym of Light Amplification
  Stimulated Emission of Radiation.
• According to Wikipedia, A laser is a device that
  emits light through a process of optical
  amplification based on the stimulated emission of
  electromagnetic radiation.
• The invention of the first laser cutting machine
  took place during the 1970s. For the past 30
  years, the continuous increase in functionalities
  in laser cutting machines has its applications.
• Laser machines cater to diverse fields like
  manufacturing, military, law enforcement, skin
  treatments, and much more.
• Below mentioned are its major qualities
• Consistency
• Brightness
• Monochromatic
• Direction
• The Working
• When the laser beam hits the surface of the
  workpiece, the light energy transforms into heat
  energy and the focused point melts because of
  thermal diffusion and forms a small spot.
• The metal vapor in the spot expands and causes a
  micro-explosion. This ejects the molten material
  and causes a highly directional anti shock wave.
  It makes a hole with a wide upper side and small
  lower side for further processing.

• Fiber laser cutting -- one of the most famous
  types of laser cutting uses high power density
  laser beams to illuminate the work area. The
  illuminated material rapidly melts, evaporates
  and reaches the ignition point. The high-speed
  airflow along with the laser beam blows the
  melted material. If you are looking to implement
  laser system for your business, you can search
  for Amada parts, Amada laser parts, Amada
  replacement parts online to find the best fit as
  per your requirements.
• Because of the recent development in this
  technology, fiber laser machines are more
  efficient. They replaced the CO2 and YAG lasers
  in thin plates cutting.
• Below mentioned are some advantages of fiber
  laser cutting
• The cost of fiber laser cutting is low because
  the photoelectric conversion rate is 30 whereas
  the photoelectric conversion rate for CO2 laser
  and YAG laser is 6-10 and 3 respectively.
• It is lightweight, has a small volume, and is
  movable with a flexible moving position.
• The laser beam passes along the optical fiber
  without the need for a reflected light path
  which in turn saves the cost of reflection lens,
  organ shield and avoids light path pollution.
• The wavelength of the optical fiber laser is 1.06
  µm and provides a benefit for sheet metal
  cutting and increases the speed by 2 to 4 times.
• Fiber laser cutting machines are useful in
  cutting the stainless steel below 4mm and can
  cut up to 8 to 10mm thick stainless steel in a
  laser beam.
• But, when the material oxygenates, the thin oxide
  film forms on the surface. And the thickness of
  cutting increases by 16mm, but the size of the
  cutting part is larger.

Overall, Fiber laser cutting is good for large
production because of its lower processing cost.
In fact, they can be useful when producing small
batches of parts. The cutting equipment is
computerized and receives data from a
computer-aided design workstation. How the
laser transfers the light path The core of the
laser component adjusts the curvature of the lens
surface with the help of water pressure, which
results in changed angle of the laser beam and at
last, adjusts it by focusing the laser movement
up and down. The focus of the laser changes due
to different diameter spots and different
working positions of the machines. In the
process, the focus of the laser light plays an
essential role. But, one more aspect plays a
vital role in laser cutting i.e. height of the
focus. It depends on the material chosen to cut
and the type of cutting machine. The focus
position varies depending on the material. For
example, in carbon steel, the focus is on the
upper surface of the plate. Whereas, in stainless
steel, the focus is about half of the thickness
of the plate. So, if you are cutting the 2mm of
stainless steel then the focus should be between
0.8 to 1.2mm. The focus position also affects the
quality of the cutting. Because the surface of
the material is uneven, the focal position of the
laser changes. If you are looking to implement
laser system for your business, you can search
for Amada parts, Amada laser parts, online to
find the best fit as per your requirements.
