E300 CNC Press Brake System Operation Manual

E300 CNC Press Brake System Operation Manual


The E300 is adedicated NC (numerical control) device for theTorsion Bending Machine,whichcombines the expertise of ESTUN for many years and provides a complete economicsolution for theTorsion Bending Machine with the support of unique drive control technology.
TheE300 device adopts the integral product structure, built-in high-performance A8 processor, andconfigures 5.6 inch, 640 × 480 dot matrix, 18 full color display screen, and integrated IO ports, serialportsand USBport.
The E300deviceis designed to be operated via the buttons on the front panel. At the same time, thepump switch and the emergency stop button are installed in the customized suspension cabinet to
meet the user’s requirements.


The E300deviceinheritsESTUN classic mode of operation, through a simple and intuitiveparameter configuration interface to complete the bending machine control operation. Its friendlyinterface, easy to use, practicalfunction, and hasthe followingfeatures:
4 axes are supported, viz, X-axis, Y-axis, R-axis and C-axis.
Automatic calculation of the block position, according to the bending angle, material, thicknessand mold parameters.
Theback gaugecan be controlled in a high-accuracysince the servo systems control X-axisandR-axis.
Optional hydraulic or mechanical to control the C-axis.
Program inabsolute valueor angle.
You can backup, restore, import andexportthe parameters, for commissioning the machineeasily.
Edit the program in one page, for improving theoperatingefficiency.
You can program the dwell time (holding time) andretracting delay by the device instead of thetime relay.
Interference or collisionof the die can be avoided.
The opening distance can be adjusted, for improving the operatingefficiency.
Automatically adjust the clamping point position.
You can view the status of inputs, outputs, valves and faults on theMonitorpage at any time.
Automatically adjust thezeropositionoftheR-axis.
Materials and die informations areprogramable.
Three of operation mode (Jog, Single,Continuous) for the jobs.
Language setting and unit setting.
IO ports can be allocated freely, and the device can detect them for avoid the repeat.
Bilateral positioningand unilateral positioning.
Slugclearance function.
Teaching or search thereference point.
The Axis, which is controlled by a servo system, can be manually moved.
Real-time memory the parameters, positions and programs against theunexpectedaccidents suchasinterruption of power supply.

You can program the bending steps for the different settings on this page. Multi-stepprogrammingiscommonlyemployed for thecomplexbending, which consist of manydifferentbending steps.

Table 2-5lists the description of the parameter on this page. You can refer to this table when you editthe parameters on this page.

We take the following process as an example to describe the programming.

In this example, there are 2 bending steps, and we can learn a set of the basic data: material is steel;one X-axis is 30 and other is 120; bending-angle is 90; thickness is 7.5;stockis 50.
We decide to program the process bythe given angle, andsupposingthe dieIDis 1.
Inaddition, we can set some other necessary parameters according to ourexperience, such asholding time is 3, retracting delay is 2, and retract distance is 5.
Follow the below procedure to perform the program.

Move the cursor on(Die), and type1.Note: For details about the setting of the die, see the section2.6Die Settings.

Move the cursor on(Thickness), and type7.5.
Move the cursor on(Material), and type1.
Move the cursor on(Stock), and type5.
Move the cursor on(Retr. DLY), and type2.
Move the cursor on(Hold Time), and type3.
Move the cursor onAnglewhereBNis 1, and type90.
Move the cursor onX-axiswhereBNis 1, and type30.
Move the cursor onRetractwhereBNis 1, and type5.
Move the cursor onBN, and pressENTERkey.

Then, pressOKon the pop-up dialog-box to create a new bending step.
Then, pressOKon the pop-up dialog-box to create a new bending step.
Thve the cursor onX-axiswhereBNis 2, and type120.
Move the cursor onRetractwhereBNis 2, and type5.
PressSTARTkey on the operation panel.
Now, the servo-axis can start to positioning. When the machine is ready, it can be produced.

The servo axes, which are controlled by servo motor, can be moved manually with the arrow keys inManualpage. You can perform this operation without starting the device.
Perform this operation can help you adjust or commission the machine.
To enter theManualpage, power up the device and wait for the device displays the default page,
and then pressF3key, as shown inFigure 2-5.


To program the process by the given angle, it is necessary to set parameters of the die.
PressF4key to enter theDiepage,

Press arrow keysUPandDOWNto select the desired dieID.
Press arrow keysLEFTandRIGHTto select the desired parameter of the die.
PressNUMERICkeys to type the proper value.
The technical parametersdiagramofthedie

H: The height of thedie, which isused in the bend depth calculation.
V: The length of V-opening, which is thedistance between the touching lines crossing.
α:Theangle of the die.
R: The radius of the edges of the V-opening.
S:Safety distance, which will be used in the case an R-axis,is mounted. This to prevent finger todie collision. The indicated minimum value iscomputed automatically from the die dimensionsas follows:
S =FS+V/2, in which:
FS = flat section on the back side of the V-groveV = opening value.
