• Laser dust removal is an important process of
  removing dust from a surface. It is also
  referred to as laser ablation. Laser ablation is
  basically the process of removing material from
  a solid surface simply by irradiating it with a
  laser beam. You can remove any type of dust with
  this method, like plastic, metallic, and organic
  dust. In this process, the laser beam irradiates
  the surface by which burnt off dust gets
  vaporized and extracted by using a proper dust
  extraction nozzle.
• Here you also need to know that dust is not the
  only element that needs to be removed from a
  laser surface. There are various thin oxide
  layers and debris present on the surface which
  might be created after a few days of storing a
  part in intensely different environments.
• However, the laser cleaning system removes all
  types of unwanted elements like stainless steel
  oxide, powder coating, rust, aluminum oxide,
  etc., from the surface. There are several laser
  cleaning solutions available like rotary tables,
  on-the-fly cleaning machines, handheld lasers,
  robot arms, etc. Also, consider replacing parts
  with quality trumpf laser parts when required.
  And for emergencies save trumpf spare parts for
  each laser part. After knowing the basics about
  dust removal methods from the laser surface, let
  us take a deep dive into dust removal
  applications, more methods useful for removing
  dust, tips for the same, etc.

Common Dust Removal Applications Laser dust
removal is popularly useful to ensure that laser
surfaces are perfectly clean before any process
like power coating, welding, adhesive bonding,
etc. takes place from it. For different results,
requirements, applications, one needs to adjust
the cycle of the laser cleaning process. For
instance, some manufacturers may require a
textured surface for improving adhesion before
coating. So how can they adjust the laser
cleaning process? They can modify the roughness
of the surface while cleaning it. This process
is known as laser texturing. Especially for
welding applications, the laser usually does not
smoothen the roughness. Instead it leaves the
metal surface unharmed to make sure that the
integrity of the part is preserved after
welding. Methods for Removing the Dust Here we
will talk about traditional methods of cleaning.
This includes manual surface cleaning,
ultrasonic baths, and burn-off ovens to clean the
dust from the laser surface.

• Manual Surface Cleaning
• In this method, you need to clean the laser parts
  with a clean cloth dipped in an adequate amount
  of cleaning solutions such as acetone. This
  method provides required results if you skip on
  mistakes like using dirty clothes, lacking
  precision, touching the cleaned surface without
  wearing sterile gloves, and forgetting to clean
  specific parts.
• Ultrasonic Baths
• Ultrasonic baths include alcohol or acetone.
  These baths emit ultrasonic waves. This wave
  then travels through the liquid in order to
  dislodge dust. This is an effective method, but
  you need professionals to handle it.
  Additionally, it is also a long and time
  consuming process.
• Burn Off Ovens
• Burn off ovens helps in getting rid of organic
  residues by decomposing them in the form of
  gases and vapors. These ovens remove powder
  coating, dust, and other residues. Burn off
  ovens are high in cost and are expensive to run.
  But these ovens make laser cleaning much more
  manageable.

• Tips for Laser Dust Removal
• As we know, a perfect process of dust removal is
  not only about cleaning the laser surface and
  removing dust. It is a process where you need to
  be careful about how you are cleaning the
  surface as it will eventually affect the quality
  of the laser parts and its surfaces. Thus, you
  should consider some important tips while
  cleaning the laser surface
• Once you have cleaned the laser parts with all
  the precautions, handle them with care and avoid
  touching them with bare hands. Always have
  gloves on your hands, otherwise, it will hamper
  the performance of the laser.
• Do not forget to perform the post-process
  treatments. Doing this right after cleaning the
  parts will help prevent dust and oxidation.
• Use an efficient dust extractor having a proper
  airflow for the cleaning purpose otherwise, you
  will end up having dust collections on the
  surface.
• Do not forget to clean the surface regularly
  after certain required intervals.
• Cover the unused areas of the surfaces.
• Make sure you are replacing your laser parts with
  quality parts like trumpf laser parts, trumpf
  spare parts, hypertherm parts, etc. when required

There are numerous benefits of laser dust
removal, like offering speed, automation,
accuracy, and consistency. Without any of this,
your final output would not come as desired.
Thus, the cleaning process is important to make
sure that the quality of your output is not
hampered but enhanced. Additionally, cleaning
laser parts with laser surfaces can help you to
increase the longevity of the laser machine. It
will directly affect how precise and clean the
output would be. Thus, make sure you follow the
given tips and clean your laser surfaces
regularly. Source https//justpaste.it/8nssa
