The Press Brake Reference
HFEM2_Mag0710_EN.indd 1 28/07/10 10:55
More than 125,000 press brakes and 1,500 bending cells installed.
Apart from Amada, which manufacturer can boast of this?
The reasons for this are simple: excellent technical knowhow, being
responsive to customer needs and producing reliable and accurate
machines. We meet our customers expectations by listening carefully to
their needs and responding accordingly.
In addition, we have equipped this model with the latest technological
developments, useful to both the operator and the investor: a new digital
touch-screen control, new man-machine interface, energy and oil saving,
with a new range of labour and time saving accessories.
The goal is to make the HFE M2 more effi cient and easier to operate but
also environmentally friendly.
The expertise acquired by the technicians of our Chteau du Loir factory is
the best guarantee of quality which we can off er. In the last 45 years over
38,000 press brakes have left the production lines, proving the pedigree
of this site.
Made in Europe

A constant angle:
The reason
The bend accuracy of a press brake is aff ected
by, among other factors, the defl ection of the
upper and lower beams.
Conventional press brakes defl ect in oppo-
site directions. In fact, the penetration of the
punch into the dies is not constant and the
angle is not uniform along the length of the
machine.
Amadas solution:
For the punch to penetrate the die unifor-
mly and naturally, and therefore to obtain
a uniform angle, Amada use the principle
of parallel deformation.
The lower beam (A) is secured to the
machine frame (B) by means of two pins (C)
in the centre of the lower beam, this allows
for a certain degree of movement. Thus,
when the cylinders exert the bending force
at the extremities of the machine, the beam
defl ections are parallel.
For the machines below 130 tonnes the
same result is obtained using a specially
designed lower beam.

NC AB Pad
The new Amada Bending Pad NC introduces a
new, intuitive man/machine interface based on
a touch-screen.
The care taken in developing the ergonomics
and our technical know-how have combined to
produce a simple, friendly and effi cient interface.
It operates on the ETHERNET POWERLINK
network principle in real time. The different
electronic elements are connected via a network,
simplifying remote connection. POWERLINK
provides safe and secure transmission of data.
To implement this system, AMDA have partne-
red with B&R, the market leader who operate
in 50 countries and who have more than 10 years
experience in this fi eld.
Maintenance was considered from the outset of
this project. It is possible to remotely monitor
the operation of the machine, transfer programs
and perform diagnostics.
Numeric Control
HFEM2_Mag0710_EN.indd 4 28/07/10 10:55
NC Functions
Drawings can be made directly into the NC by
using the new touch-screen technology.
For special applications, manual mode program-
ming allows the operator to create personalised
programs.
The operator enters the dimensions into a
pop-up window. It is also possible to indicate
bending priority.
The NC control is capable of generating
programs automatically. It takes into account
bending constraints and ergonomics, including
gauging position, component handling, bend
order and required tolerance.

Motorised X-axis fi nger, Delta X (option)
This option complements both 2 and 5 axes
versions. It allows the creation of an offset
between the two X-axis fi ngers, even when they
are close together.
It is available as a single option or as a pair.
The back-gauge
The HFE-M2 is available in two forms
2 axes X,R
5 axes X1 X2, R, Z1 Z2
The light weight but rigid design permits high
speed but precise positioning.
The gauging capacity is up to 1020 mm, allowing
the processing of large components.
In the 5 axes version, the modules X1 X2 and Z1
Z2 are programmable independently, off ering
great fl exibility.

The invertor or frequency controller produces
measurable savings.
For more than ten years, AMADA have been
committed to environmental protection.
The INVERTOR version of the HFE-M2 contri-
butes to this goal.
The addition of an invertor to the pump circuit
has the following benefi ts:
Energy saving
Noise reduction
Increased reliability
Reduced maintenance
Reduced oil consumption
Invertor
Distance pieces
The HFE-M2 is equipped with adjustable quick
release distance pieces. The loading of tools is
simple and fast.
The design also protects the upper beam from
damage.

Sheet followers SF75 (option)
The powered SF75 sheet followers are indispen-
sable for processing heavy or large components.
Entirely managed by the NC control (height,
speed, angle), they guarantee the accuracy and
quality of the fi nished product. Their capacity
(75kg per arm, 30 minimum angle) relieves the
operator of diffi cult and arduous tasks.
The machine can be equipped with either one or
two independently controllable arms.
BI-J (option)
This option overcomes the problem of bend
angle variation caused by work piece thickness
variation, quality and grain direction.
The high precision in-cycle measurement by the
BI-J eliminates the requirement for test bending.
The correction, if required, is made in real time
giving a right fi rst time bend angle.

There are several safety options to suit all
applications:
Light curtain type
Laser beam type
Angle measurement
Digipro (option)
The DIGIPRO is a digital protractor that commu-
nicates with the NC via infrared. The measured
angle value is transmitted to the NC and the
program is automatically corrected as required,
thus obtaining the correct bend angle.

Air-bending force chart
This example of an air-bending force chart is
for mild-steel (40-45kg/mm tensile strength).
From the material thickness it is possible to
determine:
Bending force
Correct V-size
Minimum fl ange size
The ideal V-size is indicated using the red
boxes. If the V-size is not available, or the
tonnage is out of range, it is also possible to use
the sizes indicated by the clearer boxes.
To fold other materials (stainless, aluminium, etc) a
multiplication factor is used for the bending force.
