HFE - New generation of press brakes
The HFE press brake series is suited to the demands of forming complex components with tight tolerances making it AMADA's high capacity, high specification down stroking press brake.
Manufactured in Chateau de Loir
Manufactured to the highest quality in our 14,000M 1509002 quality certified Chateau de Loir plant, the new HFE series will enable you to cover the full spectrum of bending requirements. With the introduction of this new range AMADA is setting a new trend in the world of press brakes and reinforcing its position as the market leader in the field of sheet metal and plate forming machinery.
2-D OPERALOG software, enables the user to draw the partprofile: It calculates the developed length, backgauge axes position, punch penetration, spring back and detects any possible collisions between piece part and the machine.
3-D environment simulation
A comprehensive bending software package, PBs permits bend simulation in a 3-D environment. Using PBs, you can prepare and test the program before going into actual production. By linking PBs to the Operateur 2000 controller, the press brake can be freed from none productive tasks.
Operateur 2000, a numerical controller dedicated to sheet metal machinery
This new PG based GNG offers total control of the bending process. A modem and ergonomic design, new programming functions, quick set up, easy operation, out standing accuracy, fast processing time and user friendly interface make it very beneficial forthe users.
AMADA has taken into account all aspects of press brake work when designing this new controller. It provides all the functionality required to ensure ease and speed of operation.
Once again, AMADA provides a complete forming system; machine, CNC control and tooling in a very modem and ergonomic package.
Ease of positional adjustment
Ergonomic and robust, this new hand wheel-teaching device is a standard feature on all HFE press brakes. This unit allows the operator to individually control the upper beam movement (Y1 and / or Y2) and all backgauge axes in order to carry out manual adjustments.
HFE press brakes are equipped with quick release punch holders on adjustable sectionalised distance pieces. This versatile system provides very simple and rapid tool change for any part type. Individual punch holders can be moved as needed. By using 100mm extended distance pieces, deep box bending can be performed without the need for any special or expensive tooling. They also allow window and hom applications to be carried out in the centre of the machine.
In the event of excessive loading, the distance pieces also protect the upper beam from damage.
The ultimate step achieving accuracy
Bend accuracy is highly dependent upon the backgauge. Five, independent axes (X1, X2, R, Z1 and Z2) are driven by large recirculating ball screws.
The high performance backgauge rail has been exclusively designed for AMADA and is made of an extruded aluminium alloy. The use of this technology allows a extremely light but strong and rigid moving element, giving maximum speed and maintaining long-term accuracy.
The standard, multi position fingers, provide sheet-gauging capacity up to 1020 mm. The 250mm backgauge height stroke give the ultimate versatility for the user.

The AMADA Digipro is a patented digital protractor, linked to the Operateur 2000 numerical control. This highly reliable precise measuring device ensures accurate measurement of the bent angle. By Simply pressing the function button, it transmits the measured angle value to the Operateur 2000 numerical control, which then recalculates the punch penetration to give a perfect angle.
Bending precision, an assurance to quality!
The bending accuracy is directly related to minor stresses and deformations in the upper and lower beams.
Under load, the beams on a conventional press brake deflect in opposite directions. A minor variation of punch penetration into the vee die will lead to considerable variation of the bend angle. Perfect control of straightness, parallelism and rigidity of the beams are key factors in achieving accurate bends.
The HFE press brakes are equipped with the AMADA's patented lower beam as standard, giving "Parallel Deflection" under all bending loads. This concept ensures consistent punch penetration into the vee die, over the full bending length under all loads and conditions.
The bottom beam is composed of a centre plate "A", supporting the worktable "E". The centre plate is mounted between two fixed side plates "B" which are in turn welded to the side frames. and "A" is supported by two large steel shafts "C", located either side of the central axis.
During bending, the reactive forces deform the centre plate in parallel with the upper beam. Consequently, the deflections, small but unavoidable, of the two beams, are of the same value, thereby ensuring that the punch penetration in the vee die remains consistent through out it's length, guaranteeing accurate bending.
The HFE machines in the lower tonnage range (up to 100 tonnes) have AMADA's new patented "Reactive Bottom Beam". The design and construction of the bottom beam is the result of extensive research to obtain the optimum parallel deflection of the beams.
