PRODUCT REVIEWS New ByBend Smart
A five-axis back gauge enables users to bend complex 3D parts .
The new ByBend Smart press brake from Bystronic is designed to increase the flexibility and , in particular , the speed of bending .
“ The ByBend Smart offers high-quality Swiss bending technology and numerous new functions at an affordable price . From the onset , we designed this press brake to offer a performance package with intelligent functions enabling users to produce parts of high quality and at low cost ,” said Bystronic .
The new press brake is now more versatile for an even wider range of applications and is reportedly 30 % faster than conventional bending ( 50 % faster with the new ‘ Efficiency Booster ’ option ). One of its flexibility-enhancing features is the insert and stroke length expansion . This upgrade , which is available with the purchase of a new machine , extends the insert height for bending tools from 480 to 580mm .
“ The additional 100mm boosts the ByBend Smart ’ s flexibility by as much as 30 per cent because this means that higher tools can be used , which enables users to produce parts with lower bending edges . This is particularly useful when bending boxes and drawers ,” explained Bystronic .
“ Another new optional feature is the fiveaxis back gauge . Until now , users had the choice between a two-axis and a four-axis back gauge system . Users who choose the five-axis system can now also use the ByBend Smart to bend complex 3D parts . For example , sheet metal products where the bending edges are not just parallel , but also at angles to each other . The various backgauge systems are an option to increase the system ’ s bending versatility . The basic version of the ByBend Smart comes with a two-axis back gauge system ,” it added .

In addition to a wide spectrum of applications , rapid bending sequences and short manufacturing cycles frequently play an important role for sheet metal users . Here , increasing process speeds and shortened set-up times are key . Bystronic ’ s new ‘ Efficiency Booster ’ is an optional feature that ensures rapid return of the upper beam , speeding up the bending process by up to a reported 20 %.
“ The machine ’ s main drive is only active when the machine is actually in operation . This is the logic of the ‘ Energy Saver ’ that reduces the power consumption of the machine while also boosting productivity as well as minimizing noise and waste heat ,” Bystronic told ISMR .
On request , higher-performance mechanics are available that enable the ByBend Smart ’ s upper beam to move at higher speeds during the rapid movement and bending phases . The ‘ Fast Bend M Safety System ’ option is a laser safety system that enables the upper beam to move almost all the way to the part that is being processed at rapid movement speed .
The high-precision laser sensor allows the ByBend Smart ’ s control to reduce the upper beam ’ s speed from up to 200mm per second ( rapid movement speed ) to 16mm per second ( bending speed ) just before reaching the metal sheet . The laser safety system functions like an intelligent brake assistant that enables the machine to move at a higher speed for longer . This offers users a speed advantage of up to 30 per cent , said Bystronic .
During the bending process , dynamic sheet followers support and guide large and thin sheets as well as heavy , thick sheets with long bending flanges . The control synchronises the movement of the bending aid with the actual bending process and the vertical movement of the H-axis . Dynamic sheet support is designed for machines with a press force of between 100 and
300 metric tons . The lifting capacity is 100kg per set ( distance of approx . 800mm from the bending line ). The dynamic sheet follower is operated at the same time as the upper beam .
“ It increases material handling flexibility , particularly for small batch sizes with changing material types and thicknesses . Optionally , there are rollers available for heavy parts . The table can be converted from plastic rails to rollers or brushes in seconds ,” explained the manufacturer .
The optional functions are available in three special packages , which are tailored to the needs of the individual users : Comfort Package ( dynamic crowning and advanced options for more flexible tooling and box bending ); Productive Package ( tooling flexibility and maximum productivity and flexibility ) and Tropical Package ( for tropical areas , hydraulic tank with oil cooling and heat exchanger on the electrical cabinet ).
The ByBend Smart and the ByVision Bending user interface offers easier bending . ByVision Bending is included in the ByBend Smart ’ s basic version . Operators launch all the bending processes with a few finger swipes on a 22-inch touch screen . ByVision Bending has an extensive database that includes the parameters for common types of sheet metal and bending tools . Depending on the material thickness and bending angle , the user interface determines the ideal bending process and suggests suitable tools .
“ Dynamic crowning ensures high-precision air bending results . This assistant function is only available in this form with press brakes from Bystronic . Using its sensor system , the ByBend Smart ’ s crowning recognizes the position and length of the sheet metal part . This sensor system is integrated directly into the ByVision Bending control enabling the ByBend Smart to automatically ensure the ideal distribution of the bending force across the entire bending length without requiring the operator to deal with complicated details . This results in precise and consistent angles with every bend ,” concluded Bystronic . n
