Economical and flexible press braking solution

The second ‘New to MACH’ press brake was shown on the MACH stand was a Bystronic AFM-EP 100 press brake with a bending length of 310 mm and a press capacity of 100 tonnes.  The machine provides an economical and flexible press braking solution requiring minimal set-up and programming times. 

Equipped with its Synchro technology, the AFM EP press brake range fulfils the high demands placed on process security by Bystronic customers.  The hydraulic crowning system and the adaptation of the periphery to customer requirements ensure that the system is flexible and that it produces good bending results across a wide range of sheet thicknesses up to 25 mm aluminium, 12 mm stainless steel and 15 mm mild steel.  Combined with an excellent price-performance ratio, these characteristics can result in economical production for customers.

The AFM EP range is characterised by its robust and twist free welded construction and simple operation combined with reliable technology and mature component design. Various arrangements are available for fixing the lower tools and a high resolution measurement system determines both the position of the upper beam as well as the compensation of the side frame deflection.

A DNC-884S PS 2D graphic control with its TFT colour screen guarantees complete control over the bending process.  The underlying Windows XP operating system ensures high operational reliability and easy, convenient operation.  The basic functions are called up at the touch of a button, the corresponding keys are arranged sensibly since they are sorted thematically.  The bending sequence is depicted in two dimensions.  The screen displays details about material handling and possible collisions between work-piece and tools or machine-side equipment.

The pressure for the hydraulic crowning is set automatically after the length and thickness of the sheet to be bent has been programmed into the DNC-884S PS.  The lower beam consists of three robust steel plates that are assembled like a sandwich.  The hydraulic crowning system ensures an even bending angle across the entire length of the bed.

Tool overloads are avoided automatically via the control package in which the maximum permitted loads for the tools are stored.  If, based on the parameters entered, bending forces are calculated that lie outside the loading range of the tools, the bending process cannot be started and an error message will be displayed.

The AFM EP press brake incorporates front work-piece supports that slide along the table. They can be adjusted manually in height and the can also be positioned all along the table.

AFM press brakes are equipped with a DNC-controlled back gauge system.  This permits the system to be positioned automatically both in the X and the R axes.  Both fingers can be adjusted, manually, laterally on the Z plane via line guides.

With its 2D visualisation of the bending cycle and hydraulic crowning system the AFM EP range is the perfect introduction into CNC press braking.
