5 Laser Cutting Maintenance Tips
If you use a machine vigorously, you know its
consequences. It would wear out sooner than
expected. The productivity and efficiency would
decrease too. This principle applies to every
machine that we use, including laser cutting
machines. If we maintain it properly, we can
enhance the longevity of the laser cutters.
Though the machines often come with service
contracts for a given period, ensuring proper
use and brand-specific spare parts like
Bystronic parts and Fanuc spare parts is
smart. However, if we look at the machines only
when they malfunction or are broken, it will
increase the cost and efforts. Therefore, it is
crucial for metal fabricators to maintain their
laser machines or it might affect their work and
quality. If maintained properly, it can help you
save a great deal. Here are the maintenance tips
for maintaining your laser machine's competency
and throughput.

• Keep the air sources clean
• Laser cutting machines use different types of
  gases like oxygen, nitrogen, or shop air to cut
  metals. Most of them use shop air as it has the
  fastest processing speed. It helps cut various
  metals like stainless steel, aluminum sheets,
  metal sheets, etc. So, for gases to cut the
  metal with perfection, ensure that the
  compressor gas is not impure instead
  moisture-free. Keep the lines clean and maintain
  the air pressure and air filtration properly. Do
  this regularly as the compressor source and lines
  affect the machine's performance, productivity,
  and working life span.
• Inspect the parts regularly
• The simplest tip to prolong a laser cutting
  machine's life is to inspect all the parts on a
  daily and weekly basis. Check if the pressure of
  working gas and cutting gas is enough or not. If
  not, replace it immediately. Check whether the
  limiting switches of each axis are sensitive.
  The indicator lights are damaged, whether there
  are any leakages, etc. See which part needs
  replacement and replace it with branded parts.

• Review your chiller performance constantly
• Like plasma cutting, fiber laser cutting uses
  heat to cut the metal. So, you should ensure
  that the equipment remains cool and doesn't
  overheat. Clean the condenser coils, filters, and
  fans so that they perform well. If there is
  debris in the filters or fans, they won't cool
  the machine. In fact, the discrepancy in the
  temperature could lead to poor performance.
• Many chillers require additives and chemicals, so
  maintain them at regular intervals.
• Ensure regulated power supply
• After one month of continuous power supply, cut
  off the main supply and check all the electric
  connections, tighten the terminals, especially
  the main circuit.
• Along with this, check the elasticity of the
  slider carbon brush, blow out the toner, and
  dust on the components using dry compressed air.

5. Inspect the gas delivery Laser machines use
gas to vaporize through the material. The
contaminated gases affect the cut and result in
poor quality. If you want a smooth cut, make
sure that the gas is pure and clean. For this,
inspect gases whenever possible. See if they are
free of debris. Look if filters are doing their
job properly. Replace the gas bottle every time
you notice a leak, as it would affect the
overall performance. Also, they are a safety
hazard to workers working with the device.
Hence, whenever you see a leak, turn off the
device and then use a soapy connection rag to
rub the connection line. Address it as soon as
you notice a leak. Any delays will affect your
performance, and even your safety will be at
risk. Conclusion Check your laser cutting
machine and parts regularly. If you find any
fault or look like a part has failed or is not
working properly, replace it immediately. Follow
the tips mentioned above for better maintenance.
Also, keep your machines clean and track every
activity. Lastly, use Bystronic parts or Fanuc
spare parts for replacement.
