Peddinghaus PeddiMat Angle Line

The Peddinghaus PeddiMat Angle Line is a CNC fabrication system purpose-built for processing structural steel angle iron — one of the most common secondary structural components in commercial and industrial construction, transmission towers, communication structures, substation frames, and conveyor systems. The PeddiMat automates the full sequence of angle iron processing: feeding from coil or bar stock, punching bolt holes, notching ends, shearing to length, and marking part identification — all in a continuous, unattended production run.

The core of the PeddiMat system is a high-tonnage punch press unit that punches both legs of an angle simultaneously, producing clean, burr-minimal holes at production rates that drill-based angle processing systems cannot match. Punching is inherently faster than drilling for standard bolt hole diameters in material up to approximately 20 mm thick, and the PeddiMat exploits this speed advantage to deliver very high throughput on repetitive angle fabrication work. Tooling changes are tool-station-based, and the machine accommodates different punch diameters within a job run.

Peddinghaus's PeddiPro control software drives the PeddiMat's servo feed axis, punch actuation, shear, and notching stations from a unified interface. NC files in DSTV format from structural detailing software — Tekla Structures, SDS/2, and Advance Steel — specify hole patterns, end preparations, lengths, and part marks for each piece in the job. The PeddiPro system queues jobs, tracks material consumption, and can interface with ERP or production management systems to provide production status reporting.

End preparation capability sets the PeddiMat apart from simple punch-and-shear systems. End notching stations can produce L-shaped notches, V-notches, and straight square cuts on angle ends to create the connection configurations required by structural drawings — eliminating downstream sawing or hand grinding for end preparations. This capability is particularly valuable in transmission tower and communication tower fabrication, where every angle piece has precisely defined end preparations and hole patterns that must be produced consistently across hundreds or thousands of identical pieces.

The PeddiMat Angle Line integrates naturally with bundle loaders on the infeed side and sorting/stacking systems on the outfeed side, enabling lights-out production across multiple shifts for fabricators processing large angle iron orders. Its closed-loop servo feed system maintains length accuracy to ±0.5 mm across the full bar length, ensuring that punched hole positions and cut lengths meet the tight tolerances required for bolted lattice structures where cumulative error across many pieces would cause alignment problems at erection.
