High-performance precision: tube bending machines for the series production of boiler tubes and tube serpentines

The ideal solution for the efficient series production of tube serpentines, the CNC DB range of automatic booster bending machines is equipped with an intuitive CNC multi-axis control unit, an integrated tube positioning device and a smart booster with programmable boost factor. The CNC DB machines are particularly precise and primarily suitable for the mandrel-free bending of boiler tubes and tube serpentines. Users who require more process customisation options can choose to add a flip-over table, terminal end bender, ejector or tube magazine.

Cold bending process for especially high energy efficiency

The BOILER & POWER range of tube bending machines are designed specifically for continuous multi-shift operation in challenging conditions. Moreover, the cold bending process, which is gentle on the material, can also ensure that the microstructure of the high-strength and alternating-strength materials remains virtually unchanged. The booster bending machines from our BOILER & POWER ranges outperform the tolerance specifications for wall thinning and ovality prescribed by all international standards including EN 12952 and ASME B31.1.
