7 Common Solutions
sales_at_altparts.com Press Brake Issues and
Being a fabricator can be a difficult job because
you need to make sure of hundreds of things like
the machining workflow, bending sheets, quality
of materials, etc. While monitoring multiple
things you need to ascertain that there is less
room for mistakes with productive output.

• But, as a fabricator there are many issues you
  must be facing in your day to day lives be it
  with the machines, sheet types or anything else.
• However, you are not alone! Here in this article,
  we are going to discuss the 7 most common issues
  you will encounter and the ways you can solve
  them with your Press Brake Machine and Amada
  clamp base assembly, Amada work holders. So,
  without any further ado lets start
• 1) Machine not getting started
• There can be multiple reasons for this type of
  problem like
• Not releasing the emergency stop button, loose
  wiring, etc.
• There are also chances of the press brake machine
  Amada clamp base assembly, Amada work holders
  not working properly if its main components like
  thermal relays, overload protection, breakdown
  of the circuit, damage of AC or there may be
  some power issues, etc.

• Solution
• Check if the three-phase power is normal, if the
  wiring has become loose then you can fix it, or
  if the circuit part isnt working then you need
  to analyze the problem behind it.
• 2) Ram cannot be bent or the bending speed is
  slow
• Yes, this too can be one of the issues you would
  be facing. Lets understand its causes
• The pressure of things like programming,
  machines tool settings, etc. is not up to the
  mark, parameters of the Y-axis are not good or
  the ram is not having a good conversion rate.
• Solution
• You need to check the value of the Y-axis. It
  should be greater than the speed conversion
  point value. If it is not greater than it, then
  you will need to adjust the parameters of the
  Y-axis and also need to make sure that the
  programming of your operation is working
  correctly. You need to check if the valves

• of the machines are proper and are working up to
  the mark as well.
• 3) The main motor automatically stops
• There are chances that the main motor may stop
  abruptly because of overheating, circuit
  breakdown or any other issue.
• Lets dive a bit deeper into understanding the
  reasons behind this breakdown
• Poor oil quality
• If you dont change the oil in the machines
  Amada clamp base assembly and other parts for a
  long time.
• If valves are not working properly or the main
  valve is stuck.
• Following are some of the solutions you can use
  to overcome this problem
• You need to immediately replace the oil of the
  machine.
• Clean the main valve and the proportional valve
  immediately.

• Replace the circuit breaker or can even overheat t
  he switch.
• Make sure to check the system output.

• Inconsistent height
• This issue occurs when the backpressure is high
  and it creates inconsistency on both the sides
  of the sheet metal.
• To resolve this issue, you just need to adjust
  the backpressure to a specific value and
  maintain its value consistently.
• Ram takes too long during transition point
• There can be multiple reasons of this problem.
  Lets see each of them in brief
• Tank suction leakage
• The Y-axis parameters are not good
• There are chances of valve failure during
  installation or the machine is not getting
  proper spring tension
• Below are the solutions to this problem

• Start with checking the rubber sheet or
  re-install the cover of it.
• Adjust the parameters of the Y-axis so your
  machine is working seamlessly.
• Make sure to check the valve installation is
  proper, check the spring tension and also check
  the core of the valve.
• 6) The calculated pressure is more
• This problem arises when
• The set of electric resistance is not correct
• The programming of the bending method is wrong
• The machine parameters modify material parameters
  or unit selection

• Solution
• Make sure that the programming is correct.
• Choose the press brake tooling in regards

to plate

• thickness and V slot width.
• Make sure that you are parameters.

• 7) Hydraulic temperature is high
• There are various factors that affect the
  hydraulic temperature
• Filter blocking, oil pollution or deterioration,
  many such factors.
• Working under high pressure for long hours.
• Below are some of the solutions you can use
• Replace the oil and filter if needed.
• Check if there is a reason to work for long hours
  and high work pressure.
• Final Words
• Having issues in the mechanical machine are very
  common and as a fabricator, you need to
  understand and try solving them. There might be
  days when you will face issues that are more
  critical than this. But, not losing your hope and
  trying to solve them patiently is the key.
