7 Critical Press Brake Mistakes You Must Avoid

Machines dont have to be brand new to produce
quality desired results. But you do have to keep
good care for them. With a press brake machine,
producing good results wont be a likely
scenario if it has an upset ram. It is an
integral part of the press brake machine. And if
that has a problem, it can hinder your whole
production process. Hence, it is important to
practice proper maintenance practice to maximize
its shelf life. From where the problem
arises? Sheet metal fabrications, while going
through the press brake machine, change its
shape from a sheet into a three-dimensional
shape. If those bends are not straight, the
final assembly wont go the right way. If you do
not maintain your press brake machine, the bend
follows a curved line rather than a straight one
that is canoeing.

• In order to avoid that, here are the seven most
  common press brake mistakes we should avoid to
  ensure its smooth working.
• Not Taking Care of Gibs
• Gibs are the small components of the press brake
  machines. They lead the ram and tool as it makes
  movements. If you neglect its regular
  maintenance, the ram can twist and jam. Hence,
  it is important to adjust Gibs regularly and
  provide proper lubrication from time to time.
• Lubrication of the Machine
• Apart from lubricating the gibs of the press
  brake, it is important to apply lubrication to
  other parts of the press brakes as well. If not
  then it may lead to metal-on-metal contact which
  causes wear and reduces the force available for
  the actual bending metal.
• At the same time, lubricating does not mean
  slapping on too much grease. It even means not
  putting on the wrong type of lubricant in the
  wrong place. Applying excessive grease means
  attracting dust and metal fragments. It may cause
  sliding surfaces which would accelerate wear,
  causing seal leaks.
• The key here is to maintain a machine with a film
  of oil on it. Because if it is too thick, it may
  increase drag and not penetrate between
  components.
• Here are some other mistakes we should be
  avoiding while using, assembling or selecting
  press brakes.

• Placing parts too close
• Fabricators often do this to bend radius. But
  while putting features too close to the bend
  radius or at the edge of the die opening would
  change the features. They may no longer be able
  to hold necessary hardware near the bend radius.
  The position of the features should be according
  to their thickness. And lastly, if the feature
  has to be nearer to the bend than recommended,
  our advice would be you extend the opening past
  the bend line. And if you are already facing this
  problem, you can search for Amada press brake
  for sale or used Amada press brake on the
  internet to find the right part or machine.
• Forming offsets too close to one another
• If you set the Offsets that are too close to one
  another, they wont be producing standard press
  brake tooling. Plus, these offsets would require
  special tooling that is not worth the extra
  expense for low volume orders. Refer to this
  image to choose the suitable standard offset
  size. You can contact your engineer if your
  measurement is outside of this table
• Not changing the hydraulic fluid
• Most press brakes have complex systems. And as
  time goes, hydraulic fluid would become
  contaminated with dirt, air, and water. It would
  limit the load that the press can apply. It

• reduces the lifetime value of the key components
  of the press brake. Hence, it is important to
  regularly change the fluid.
• Upsetting the ram
• When you apply uneven forces or if the load is
  too high, you can upset the ram. The root cause
  of this issue is its position while bending the
  metal which is not in the right place or not in
  the center. It is important to note that if the
  metal is too thick or not enough load is there,
  it could hurt the ram as well.
• A bend radius that is too tight for the material
• Keeping your radius right is paramount. If it is
  too tight, it can cause a permanent deformity
  that alerts the dimensions of the part. It is
  important to understand that different metals
  have minimum bend radius-to-thickness ratios.
  Hence, the harder the metal, the greater the
  minimum bend radius.
• Machinery parts for the press brakes are
  sensitive. If not cared for properly, that time
  is not far when you would need to rebuild the
  whole machine.
• It is a must to avoid the above-mentioned
  mistakes for a full-proof and versatile press
  brake. If you are starting over, you can try
  searching Amada press brake for sale or used
  Amada press brake over the internet to find the
  products which would help you put together a
  quality press brake machine.
