Mandrel-Free Tube and Profile Bender CORMAK BENDMASTER 70 – precision tube bender for large-diameter steel tubes

The Tube and Profile Bender BENDMASTER 70 is an industrial mandrel-free machine designed for precise bending of steel tubes, square profiles, and large cross-section materials. With its solid construction, automated bending angle measurement system, and powerful drive, the machine guarantees repeatability, efficiency, and reliability – even under heavy-duty production conditions. It is ideal for applications in heavy industry, construction, and industrial installations.

Main advantages of the machine

• Mandrel-free bender – enables tube bending without the use of a mandrel, simplifying operation and speeding up production.
• Maximum tube diameter 70×5 mm – suitable for thick-walled steel and structural tubes.
• Main drive power 5 kW – ensures high torque and reliable bending of even the toughest materials.
• Digital bending angle display – allows real-time monitoring and precise parameter setting.
• Two-speed operation – 1.2 rpm for bending and 2.4 rpm for return, increasing work cycle efficiency.
• Stable welded steel frame – resistant to deformation and vibration, even under heavy load.
• Dies for 38.1 mm, 48.3 mm, and 70 mm diameters – included for the most common industrial tube sizes.

Construction and technology

BENDMASTER 70 is designed as a mandrel-free roll-type bender with an electro-hydraulic drive, adapted for heavy-duty operation. The 5 kW main motor ensures stable and safe bending of large-diameter tubes. The digital bending angle measurement system, integrated with the control panel, allows accurate programming and monitoring of working parameters. Its compact design enables integration with production lines and ensures long-term reliability.

Precision and performance

The BENDMASTER 70 steel tube bender offers full control over the bending process. The 1.2 rpm bending speed guarantees accuracy and process safety, while the 2.4 rpm return speed increases efficiency. Bending up to 180° allows forming of full arcs and spirals, even in large structural tubes. The machine is designed for precise forming of components where tolerance and repeatability are critical.

Applications

The BENDMASTER 70 bender is used across multiple industries, including:

• production of steel and load-bearing structures,
• construction and assembly industry,
• HVAC and heating installations,
• manufacture of balustrades, gates, and industrial fences,
• prefabrication of piping systems.
