BENDMASTER 70 Tube and Profile Bending Machine

The BENDMASTER 70 tube and profile bending machine is an industrial, non-mandrel bending machine designed for precise bending of steel tubes, square profiles, and materials with larger cross-sections. Thanks to its robust construction, automated bending angle measurement system, and powerful drive unit, the machine provides repeatability, efficiency, and reliability – even during intensive production work. It is an ideal solution for heavy industry, construction, and industrial installation applications.

Main advantages of the machine
Non-mandrel bending system – enables tube bending without the need for a mandrel, simplifying operation and accelerating the production process.
Maximum tube capacity of 70 × 5 mm – allows processing of thick-walled steel and structural tubes.
5 kW main drive motor – provides high torque and reliable bending performance even with demanding materials.
Digital bending angle display – real-time monitoring of preset and actual values enables precise parameter adjustment.
Two-speed operating system – 1.2 rpm during bending and 2.4 rpm during return movement increase overall cycle efficiency.
Stable welded steel construction – ensures resistance to deformation and vibration, even under heavy loads.
Dies for tube diameters 38.1 mm, 48.3 mm, and 70 mm – the machine includes tooling for the most commonly used industrial tube sizes.
Design and technology

The BENDMASTER 70 has been designed as a non-mandrel roller bending machine with an electro-hydraulic drive system, suitable for heavy-duty operation. The powerful 5 kW main motor enables stable and safe bending of large-diameter tubes.

The digital bending angle measurement system integrated with the control panel allows precise programming and monitoring of operating parameters. The machine features a compact design and can be integrated into production lines.

Precision and work efficiency

The BENDMASTER 70 steel tube bending machine provides complete control over the bending process. The die rotation speed during bending (1.2 rpm) ensures accuracy and process safety, while the fast return speed (2.4 rpm) improves productivity.

The ability to bend up to 180° allows the production of complete arcs and spiral shapes, including large-section structural tubes. The machine is designed for precise forming of components where dimensional accuracy is critical.

Applications

The BENDMASTER 70 bending machine is used in many industrial sectors, including:

production of steel structures and load-bearing components,
construction and installation industries,
HVAC and heating system installations,
production of railings, gates, and industrial fencing,
prefabrication plants for piping systems.
