Key points of CNC bending process for thick-walled steel pipes, processing techniques for large-diam

English Keywords：thick-wall steel tube bending, large diameter CNC bending, heavy tube processing

Thick-wall and large-diameter steel tubes are widely used in construction machinery and steel structures. Featuring high hardness and rigidity, they require heavy-duty rigid CNC benders to avoid vibration and position deviation. 

Key processing tips: adopt high-rigidity machine frame and reinforced dies, reduce bending speed for uniform force, set sufficient spring-back compensation (thick tubes have larger spring-back), and form steadily through die fitting without mandrels. 

Operators must verify machine load capacity before processing large tubes to prevent equipment damage and dimensional errors.
