BIG PRESS BRAKES

These are special machines which can be used to bend Long length sheets in a single bend. The maximum length in this range comes upto 8 mtrs. Above this length then we have to go for a Tandem Press Brake. These range of Press Brakes are only available in CNC mode of Operation. In longer lengths Press Brakes the synchronization of the cylinders is Hydro-Electric as Torsion Bar is not successfull.

CONTROLLERS

Controls the running of the Press Brake by Determining Parameters, Bending Angle, Stroke, Speed Changing Point from rapid speed to working speed. Speed changing points can be controlled according to the part program by the continual online communication between the laser safety equipment and the CNC.
Delem - known worldwide for dedicated Press Brake & Shear Cotrollers. Delem - offers basic New DA-51 & DA-56 Controller for Axis Press Brakes. Delem's new generation of 60 series controller operates under Windows and offers peripheral applications, analysis tool, networking, remote diagonistic options.

STANDARD CONTROLLER FOR 3 + 1 Axis

The DA-51 offers all basic CNC control functions upto 4 axes and angle programming of the Y axis. The bright LCD display including backlight and the modern front panel layout guarantee a very user-friendly and easy to program controller.
For part programming it provides the user programming space for 500 program lines where each program can contain 25 bends maximum. All bend parameters of one bend are listed on one page.
For each program there is one extra page available to specify a.o. tooling, material properties and stock count.
The basic machine control functions are Y1-Y2-X axis, optionally a second servo axis to be used as R/Z or X2 axis control and/or a 3 position pneumatic R axis control.
The CNC control is able to drive a crowning device.
The compact control gives highly flexible mounting possibilities and is pin compatible to the graphical programming unit type DA-51.
