Press Brakes: Types, Toolings, and Bending
Methods - You Should Know Before
Selecting
Do you want to buy the new press brake machine, or the older
one has become a headache for you? To find a good one, you
can try searching "​Amada Press Brake for sale​" online, and you
will come across some results to select from.
You will come to know different types of press brakes for
bending metals. Not only types, but there are other factors as
well to consider while selecting one.
Before discussing the types, let's have an overview of press
brake machines.
Little Bit About Press Brake
Press brake is the pressing tool for bending metal sheets and
other materials. Usually employed for sheet metals, it forms a
curve by pressing the material between the machine and die.

The bending process may repeat several times to gain the
desired form of metal. The machine is typically narrow and
long, so the issue of bending the long sheet metal is no more.
These days, when individuals talk about press brakes, they
mainly refer to hydraulic press brakes for bending. However,
there are other types of bending machines as well in the
market. Let's discuss them:
Types of Press Brakes
● Manual Press Brakes
It is a common type of press brake, also known as sheet metal
brake. In manual press brakes, one needs to manually set the
dimensions and angles when used. It consists of the work table,
supporters, and the clamping plate.
As it requires manual work, operating manual press brakes is
much more intricate than other press brake machines.
So for getting optimum results, it is recommended to make
mass production. After completion of one batch, adjust the
dimensions and angles for continued production.

● Hydraulic Press Brakes
Need reliability and low cost of production? Hydraulic press
brakes are better alternatives. As said, these press brakes are
mainly used for industrial purposes for bending sheet metal
products.
Joseph Bramah first introduced the hydraulic press brake in the
17th century (1795). It is one of the oldest press brakes
available in the market and can handle the heaviest workloads.
This trait makes it common in the industrial sector.
It works on Pascal's law "When there is an increase in pressure
in a uniform fluid, then it is equally transmitted in all the
directions."
Based on this, hydraulic (water-based) press brakes produce
the compressive power with the aid of hydraulic cylinders.

● CNC Press Brake
CNC (Computer Numerically Controlled) twisting is the
assembling cycle completed by the CNC press brakes. It offers
high control, bending, and repositioning accuracy, which makes
it easy to use.
When operating CNC press brakes, you just need to input the
number of pieces required for each step's bending and bending
angle. The CNC machines will work as per your configurations in
the controller.
Now you know the major press brake machines, you can find a
good machine by searching Amada press brake for sale. Not
only the good machine but the tooling is also crucial for giving
form to the sheet. Let's discuss them.
Toolings
The press brake dies are the tools applied by press brakes to
carve a sheet metal. There are different types of toolings to
form sheet metal. Let's discuss them.

● V-Dies: ​Used for giving V-shaped bends.
● Curling Dies: ​Used to curl the edges of the sheet.
● Acute Angle Dies: ​Used in air bending to create acute,
obtuse, and right angles.
● 90 degree dies: ​This die is majorly used for bottom
bending.
● Offset Dies: ​Punch and die set that bends two angles in a
single blow to form a Z shape.
Bending Methods
Tooling has a major effect on the form of the sheet metal. So
you must buy good quality parts like ​Fanuc replacement parts
for your press brake.
Type of Bending Method
● Bottom Bending
Bottom bending, a contrast of air bending, presses the sheet
metal against the slope of V, with air between the sheet and
the bottom of V opening.

● Air Bending
In air bending, the workpiece will come into contact with the
edge of the die and the tip of the punch. The punch presses the
sheet into the V opening without touching the bottom.
● Coining
The coining method involves stamping the workpiece between
the punch and die. This method is highly accurate and
achievable with older machines.
But this method is more costly than air and bottom bending;
therefore, it is irregularly applied.
End Words
The right press brake machine can make or break things, and it
is important for the manufacturer to select the right one. Not
only the press brake machines but the workpiece and
requirements also need your attention while selecting.

If you need the machine to handle the heaviest workload, then
a hydraulic press brake is your way to go. Rather than doing
manual work, if you need to automate the process with some
configurations, then the CNC press brake is a better option.
