Modern and flexible

The PC-based control system for 3-roller bending machines was developed by PBT, and in 1995 it was the first to offer the capability of controlling bending tasks using software. The PC400 is currently the most advanced and flexible control system on the market, and offers countless advantages for small and large series production processes.

Intuitive operation

On the basis of a high-performance Windows PC with a state-of-the-art multi-touch display, bending programs can be created, managed and controlled intuitively on the moveable control terminal, without the need for programming skills. Here the graphic display of the programmed workpiece allows visual inspection of the programmed data. The hardware is network-compatible and can easily be integrated into the existing IT infrastructure.

Efficient and economical

The control programs generated allow any number of different segments to be arranged in sequence and bent in one or more passes. Subprograms for the creation of ellipses, handrails for spiral staircases, “Napoleon curves”, S-curves or special shapes are already available as standard.

By means of precise control of the X and Y-axis, perfect transitions are achieved between radii and straight sections. Non-conformances caused by the machine are excluded through the continuous regulation of the axis position during bending, from individual parts to large-scale series production. Unavoidable non-conformances in programmed data, which can result e.g. from different material elasticities, are corrected in the software by entering actual manufactured values – consistent repeat precision and low reject rates are thus ensured.

Open and expandable

With the PC400 control system, an open system has been created. Whether integrated into a network or as an individual work station, by means of Siemens S7-1200 the new PC400 also allows the integration of supplementary modules in addition to the control of machines. In this way the PC400 becomes the central control unit for e.g. the 3D bending / turning device, automatic radius measurement system, minimum quantity lubrication MMS, mandrel forward feed or even robots.
