The video follows an automatic straightening press on a production floor: shafts arrive by conveyor, the machine measures, straightens and re-checks each one, and good parts exit without waiting on a skilled press operator — a direct replacement for the manual straightening cell that typically bottlenecks heat-treatment output. The machine can be placed directly after the tempering furnace or before centerless grinding so bent parts never queue between operations.
Cycle times of 20–90 seconds per shaft mean the press keeps up with machining and grinding lines, while closed-loop control delivers 0.02–0.05 mm TIR on automotive shafts and logs every part’s results. One operator can oversee one or two CNC machines instead of working a floor press full-time. The automation trade-offs are laid out in our article on hydraulic, CNC and fully automatic straightening.
Typical deployments are in axle, transmission, motor and fastener plants running repeated part numbers, where recipe changeover between batches takes minutes and conveyor, gantry or robot loading can be added as volumes rise, and every shaft carries a stored runout reading for quality records. Start with the configurations in the automatic machine range.
