KEY FEATURES

USER-FRIENDLY PC-BASED CNC CONTROL

Powerful Touch-B PC-based Windows® Control ensures fail-safe operation of the machine while offering the operator considerable assistance in part programming

Exclusive CADMAN®-B 3D bending software allows automatic programming of the part and precise determination of the blank size

Bending sequences are automatically determined from the userdrawn 2D part created with the simpleto-use graphics editor

All axes of the press brake, including the CNC crowning system, are calculated by the control and are automatically positioned for optimum bending results

2D & 3D color graphics simulate part creation and display material handling sequencing for optimum part production

Tool libraries and interactive databases are maintained automatically for application of the precise bend allowance factors and angle correction values, ensuring accurate fi rst time bends with minimal or no trial bending

New Touch-B control provides the fastest and most accurate way to produce parts on a press brake today

New graphic interface ensures fast art to part times

Programmable Crowning System V-axis

CNC crowning ensures the ram and table are parallel during the bending operation

Sheet thickness, length, die opening and tensile strength data are entered into the control

Force and related defl ection of the table and ram are automatically determined, preloading is optimally obtained for each bend

Microprocessor Technology for Optimum Precision

Press brakes up to 400 tons are designed and built utilizing a welded one-piece frame, machined without repositioning, guaranteeing machine precision

Hydraulic cylinders are machined from a solid steel billet

Pistons are steel forgings, precision ground and micropolished for years of trouble-free service

Microprocessor Technology for Optimum Precision

Servo-controlled using state-of-the-art hydraulics and electronics to ensure perfect control of the bending process

Double bed referenced encoders are connected to the bed in such a way that deformation of the side frames during bending does not influence the positioning accuracy of the upper beam (Y1, Y2)

Easy-Form®Laser Measuring System

Patented system (EP 1 102 032) allows exact measurement of the angle during the bending process

Laser sensing mechanism tracks the plate during the bending process and transmits the digital information in real time to the CNC control unit

CNC unit processes the information and subsequently recalculates the depth adjustment to obtain the correct angle in real time – with no process interruption and no loss of production time

With LVD PPEB and Easy-Form press brakes, you obtain an optimal bending process and excellent bending results — from the first piece.
