The RB Classic series covers our classical machines primarily for round pipes with a maximum diameter of up to 2,032 mm and up to a pipe weight of 20 tonnes. This series is also suitable for square & rectangular pipes. The maximum dimensions for square & rectangular pipes can be seen in the table of technical data.

Thanks to numerous technical optional extras, these technologically complex machines can be individually adapted to customer's specific needs. The various machines of the RB Classic series can be equipped with up to 7 CNC axes. The 7th CNC axis is necessary for cutting square & rectangular pipes.
Detailed information can be supplied on request.
