Product Application

The ACCURL® NC press brake , engineered with great care for details , is a high quality machine tool . The studies made on the framework flections have allowed us to design a product that reacts in the most appropriate and responsive way to the mechanical solicitations , therefore guaranteeing a stable structure , thus a higher precision in bending. This feature is even enhanced by a system of manual crowning . Worth mentioning is also the possibility to add options and upgrades on the configuration , at later stage .

Machine Parts

● Machine Frame
ACCURL® machines are designed from the ground up by our expert engineers with only one goal: to build the best machines imaginable . By combining our unique machine designs with the highest quality materials available , we have achieved our objective and invented some of the most reliable and durable machines in the world .

● Hybrid System

ACCURL® is introducing the hybrid system at the same price as theconventional system, leading to a series of advantages for the customer:a huge energy saving ( 55% if compared to a traditional machine ) and amassive reduction of the oil quantity needed, thanks to the double tank .

● Hydraulic Cylinder
All seals in cylinder is PARKER from USA,Being able to work under rated load continuously , stable working and high precision .

● Double Guided Ram
The double guided ram ensures the stability and the ram-working table perpendicularity . This allows to keep the high precision during the whole bending phase , even with different tools and intermediates, thus ensuring the centering made during the initial tests in time .

● Ram Positioning System
Main Torsion bar machine limitations:
1) Always for center bending ( No off center )
2) No conic bends – Y1 = Y2
3) Impossible tandem connection
4) Mechanical synchronism on Y1/Y2

● Punch and dies
Full length multi V series of 835mm punches with a fractioned one

● X - Axis Back Gauge
ACCURL® press brake are provided are equipped with a back gauge that automatically adjusts the X (depth) axes to ensure your material isalways positioned accurately, resulting in higher quality finished parts.

X-Axis CNC BackGauge:
1) X precision servo-driven back gauge
2) Manually adjustable R and Z1 , Z2- axis
3) High - Speed with HIWIN linear guides
4) Driven by DELTA Servo Motors and drives
5) Complete Backgauge fingers on double linear guide
6) X – axis speeds up to 800 mm / sec and accuracy to 0.01mm

● Speed Arip System
The speed arip system reduces the time spent changing tools by 8.5 times compared with traditional systems .

● Foot Switch
Foot switch from Germany's Siemens ( Category 4 )

● Safety Light Curtain
Back of the machine safety light curtain

ACCURL® product designs combine accuracy, speed, flexibility, durability, reliability and advanced technology to deliver machines with the highest performance-to-price ratio in the industry.
