The high-precision welded, stabilised and machined steel chassis has been designed to eliminate any types of stress. The S-bend included in the hydraulic press...

Back gauge The back gauge is fitted with ESA servo motors and precision BOSCH REXROTH recirculating ball screw guides which permit automatic positioning of X and R axes with 0.05 mm precision. It also has a manual adjustment system for the Z axis which enables the gauge callipers to be slid easily along a guide with recirculating ball screw system. The parallel alignment of the gauge callipers with the press brake punch holder plate is adjusted manually using micrometers to ensure maximum precision. In addition there is a mechanical offset system for Z axis curvature so that deviations can be...

Laser sensor The laser sensor system built in to the press brake has a metric guide to facilitate vertical adjustment and can easily be lifted up and removed when work tools (punches and dies) need changing. The system includes two electronically controlled high-frequency laser emitters and receivers which are able to recognise and ignore any external light source and are thus protected from interference by any other lighting, whether natural or artificial. In addition, for complex bending operations on sheet Hydraulic unit Centralising all the hydraulic components in a single unit improves their...

Promecam punch clamping system Precision bending The Promecam punch clamping system with segmented flanges can be taken apart and adjusted from the front by means of screws. The Euro Promecam guide rail system permits dies to be changed quickly without needing tools. For maximum bending precision a GIVI MISURE high-resolution (0.005 mm) optical encoder is used, which controls the vertical position of the bending axis (Y axis) for excellent reliability in each operation. Combined with control of lowering speed, this ensures punch holder plate vertical axis precision for bending operations and...

CNC Control The powerful ESA S630 CNC control system has outstanding processing capacity which permits up to four axes to be managed, interpolated in any combination Y, X, R and Z, providing solutions for the most complex bending operations, and a flash memory for 5000 programs and a full library of Promecam punches and dies. CNC control is the core which runs all the systems and which now includes, amongst other innovative solutions, the adaptive electronic pressure control which calculates the force required for each operation and thus lengthens the life cycle of punches and dies; the electronic...

Sheet metalwork and bending sequence calculations The complex algorithms processed by the CNC control enable the total worked length of the sheet metal to be obtained accurately according to the bending program. Furthermore, bending sequence management makes it possible to select the most suitable option for producing each piece, ensuring greatest ease for user who also has invaluable help in the form of the efficient 2-D visual bending simulator, which displays the positioning of the sheet metal in the press brake during each stage of the process, in addition to graphics display of the progress...

CNC control also provides precise management of different types of bending, such as: 1. Air bending: where the sheet metal being bent with the punch does not reach the very bottom of the die. This enables different bending angles to be obtained using the same tools, which requires extreme precision to guarantee a perfect result. 2. Bottoming: the punch forces the sheet metal to the very bottom of the die. The bending angle obtained depends on the tools used. 3. Stamping: the sheet metal can be folded upon itself to give higher strength in specific areas. 4. Roller pressing: this enables different...
