Precision and quality check in one work step

A high degree of precision avoids unnecessary waste of expensive materials. “Ideally, the tubes are already checked during the bending process and the results corrected, if necessary,” explained Mr Korte. integratable measuring system from Schwarze- Robitec determines the spring-back value directly after bending of a tube, and the CNC control uses this to calculate the necessary re-bending angle.” Re-bending is done directly following this – if desired fully automatically or after release by the machine operator. The bend is carried out precisely to half a degree deviation “The optionally

With the help of the measuring system integrated in the bending tool, tube processing companies can bend, measure and adjust in a single operation

and nearly every component is a useable good part. The complete process only takes a few seconds per work piece on average. In comparison, measuring and adjusting by the conventional method require about three to five minutes. The operator also benefits from the integrated measuring system: if the previous manual calculation posed an increased source of errors and cost the operator time, the work steps are now considerably simplified. At this point it shows that the operator-friendly and safe production processes are important factors when dealing with profitability in shipbuilding and plant construction. When work steps such as machine re-fits or checking tubes on separate systems are omitted, the operators have less physical stress, and it leads to a higher degree of occupational safety. From solutions for time efficiency to concepts for material savings and all the way to work-simplifying extras: all these need to be taken into consideration when production processes are to be designed economically and sustainably.

have been used in production unrestrictedly for far more than 35 years. The Schwarze-Robitec product range includes, in addition to tube bending machines and bending tools, tube perforating machines, measuring stations, and solutions in the area of special machinery construction.

Schwarze-Robitec GmbH – the Company

The company, founded in 1903, is a leading producer of tube bending machines. Since 2011 it has been run by the managing directors Bert Zorn and Hartmut Stöhr. At its headquarters in Cologne, the specialist for automatic cold bending machines currently employs 130 staff. The company is represented worldwide via long-term partner enterprises. Schwarze-Robitec manufactured the world’s first CNC-controlled tube bending machine back in 1977. To date, more than 2,400 machines have been sold – some of them
