The video presents a complete steering-rack straightening production line running unattended: gantry and robotic systems load hardened racks, laser inspection stations measure straightness, the straightening press corrects bend in a closed loop, and finished racks are unloaded and transferred out — with no manual handling between the incoming and outgoing conveyors. The line can also segregate any rack outside tolerance into a separate audit bin and mark each accepted part, so every shipped rack carries a readable result record.
Laser measurement at infeed and outfeed gives traceable straightness data for every rack, tooth-friendly tooling protects the gear flanks, and the line runs at 20–90 seconds per part to match rack machining takt. One worker can oversee several fully automatic machines rather than straightening by hand. See how the inspection works in our article on TIR and laser runout measurement.
The line is engineered for automotive steering-rack suppliers who need consistent geometry for quiet, precise steering, and it integrates with existing heat-treatment and grinding cells. Layout, automation level and rack length are configured to order; the automatic machine range shows the building blocks.
