C-Frame:

o The robust machine frame consist of a welded construction: 1 EA press table, 2 EA side columns, 1 EA connecting beams

Press Beam:

o High rigidity, ensures exact bending results o Press beam is guided using doubled roller bearings at each side o Guide rollers in the Z direction stabilize the press beam and prevent radial forces on the cylinder seals o High, constant bending accuracy is achieved using hardened bars and adjustable “zero-play” setting

Spherical bearing of the press beam with press beam tilting:

o Spherical connection between press beam and cylinder o The tilt position enables the production of geometric shapes such as funnels and allows simple corrections to be made when producing long profiles o Spherical bearing prevents cylinder damage (leaking) due to radial forces caused by press beam tilting

On-Demand Servo Drive with 4-Cylinder-technology:

o Very quiet and highly energy-efficient electro-hydraulic drive o Position control is performed by two synchronous servo motors which only operates during the bending process o High axis speeds and accelerations (rapid downward movement, Y return and closing movement) enable high productivity o 4-cylinder technology reduces the deflection of the press beam and thus ensures higher part precision o Flat design of the 4-cylinder technology increases the bending space in front of the machine

Distance measurement system (Y-axis) with dynamic deflection compensation:

o High positioning accuracy of the press beam (Y axis) is ensured by high-precision glass scales

Hydraulic oil filling (life cycle):

o Machine delivered with a full oil tank o Oil has service life of 10 years

Bend Guard Back gauge:

o Gauge fingers, 2 pieces o Wear-resistant gauge fingers ensure constant flange lengths o The work piece can butt against the back gauges at three different positions o Easier back stop positioning of larger work pieces is possible by resting them on the gauge fingers

Operation:

o Operating unit with foot switches; easy positioning, stroke triggering with emergency stop, press beam up and emergency stop push-button o Communication rail: enables the use of ACB modules, MobileControl, MobileControl Pro and

Magic Shoe Display, up to 8 Modules can be used at the same time

MobileControl:

o Contains the most important control functions such as open/close tool clamps or program start/stop o Placed anywhere in the communications rail, reduces walking distance to the operating panel

Safety features:

o CE marking and EC machinery directive o Machine is secured with emergency stop push-button o Lateral sliding doors with electronic monitoring and large laminated safety glass panes o Rear roller gate at the rear of the machine is electrically operated and makes the entire machine length easily accessible without obstruction

Options:

o Advanced standard configuration:

o Manual wedge crowning

The crowning compensates the deflection of the press beam and the press table during the bending process to ensure a constant bending angle along the entire bending length

Crowning function is achieved through relative mutual displacement of two wedge plates (lower wedge plate is integrated in the press table, upper wedge plate is mounted so it is displaceable)

Crowning value is automatically calculated by the control and manually adjusted using a crank

Wedge crowning enables a very precise adjustable and even crowning curve o 2-axis back gauge (X and R axis)

X and R axis are freely programmable and enable infinitely variable adjustment of gauge depths and heights

Precise flange lengths are achieved thanks to the positioning accuracy of the axes The gauge fingers can be moved manually in front of the bending line in the Z direction without any danger The high axis speeds enable high productivity The drive in the X direction is generated with a helical rack and pinion drive and is therefore especially quiet o Manual upper tool clamp the single piece tool clamp is clamped using Allen screws and centers the tool automatically the head and shoulder-bearing tools can be rotated by 180° o Pneumatic lower tool displacement (I axis) the lower tool clamp is mounted on the press table in such a way as to make a displacement in the X direction possible displacement is performed by pneumatic cylinders and both end positions of the I axis are defined by using different spacers this function increases productivity and flexibility and at the same time enables easier removal of very high boxes typical applications are quick folding on a tool station, the use of multi V dies or station bending with tools of differing heights o Integrated technology data the control calculates all bending parameters based on the technology data for standard tools and standard materials modifications for customer-specific materials or tools can be performed by the user o Operating panel: support arm with height adjustment

The height and inclination of the operating panel can easily be adjusted to the needs of the operator

The operating panel can be easily swiveled into the working area o Shop floor programming

Demo version for generating 50 NC programs Automatic creation of a program proposal based on 2D and 3D data Manual modification of bending programs possible Program automatically generates the 3D-simulation including collision monitoring Creation of the NC program o Tool setup optimizer (trial) Automatically optimizes a range of different bending programs to a minimum of setup plans Reduces set up time and increases productivity o Installation, initial start-up and instruction o Electrical cabinet air conditioning up to an ambient temperature of 40 °C

Cooling unit to prevent overheating of the electrical cabinet Electrical cabinet air conditioning guaranteed reliable machine operation at ambient temperatures of up to 40 °C o Back gauge:

o 4 axis back gauge (X, R, Z1 and Z2 axis) In addition to the CNC-controlled axes of the 2-axis back gauge the gauge fingers are automatically positioned in the Z direction Higher productivity, especially when bending work pieces at multiple tool stations o Tool clamp:

o Hydraulic upper tool clamp

Short setup times of the upper tools at the push of a button due to hydraulic clamping Tools are clamped with clamp pistons, guarantees secure clamping of various tool segments Tool clamp is hardened o ACB Laser (automatically controlled bending) Cost-effective bending with high angular accuracy and consistently high quality starting with the first part In addition to angle measurement, the ACB laser performs automatic regulation to the required nominal value Complex run-in procedures are no longer required: the system automatically compensates for changes in the material properties The measurement is performed optically from two sides using measuring units The measuring units are positioned automatically by CNC control The measuring units can be parked at the side outside of the working area (left and right) o Front work area illumination

Lightning is integrated in the machine housing and as such does not present an obstruction

Modern LED technology works in an energy-saving way, without producing heat and has a very long service life o Rear work area illumination Lightning is integrated in the machine housing and as such does not present an obstruction Modern LED technology works in an energy-saving way without producing heat and has a very long service life o Material handling:

o 4 support bracket

Support brackets can be manually adjusted in the Z and R directions and can be fastened using quick clamping devices

Support table can be manually adjusted in the Z and R directions and can be fastened using quick clamping devices

Support table can be moved in the X direction Support brackets make it easier to handle large , heavy work pieces or can also be used as deposit surface for blanks Support bracket is equipped with a low-scratch plastic support Carrying capacity: at least 100KG per support bracket o Safety:

o BendGuard

BendGuard is an optoelectronic safety device which makes quick and safe bending possible

The maximum Y rapid speed is permitted without restriction with foot operation alone Simple and quick setting of the tool height using a scale with counterweight BendGuard can easily be pushed out of the working area for lateral tool setup operations and does not need to be adjusted again afterwards BendGuard is not sensitive when it comes to bumps and impact (misalignment) because its electronics are separated from its housing
