This video follows a tube through an automatic tube bending and straightening machine cell: bending first, then in-line straightening without the part ever leaving the fixture chain. Conveyors transfer the bent tube to the straightening station, where sensors re-measure the formed shape and correct only the residual deviation, preserving the designed bend angles.
Combining the stations cuts handling and delivers a finished tube every 20–90 seconds — typically 5–10 times the output of separate manual operations. The cell handles Ø5–600 mm tube from 100 mm to 12 m, probing 5+ points along long beds, and holds 0.10–0.30 mm/m on standard fabrications or 0.02–0.05 mm where bent tubes feed robotic welding lines downstream.
Furniture and fitness equipment makers, exhaust system suppliers, agricultural OEMs and construction metalwork shops use these cells to replace slow, skill-dependent hand straightening with repeatable, logged cycles. Because the tube never leaves the automated chain between bending and straightening, work-in-progress inventory between the two processes drops and the risk of handling damage to finished bends is largely eliminated, while floor space stays compact.
