The servo hydraulic bar stop ensures that the distance between blade and bar stop is constant throughout the whole shearing process.
On the left, a steel part with shearing break-out produced with a mechanical bar stop. On the right, a steel bar without shearing break-out, produced with the servo hydraulic bar stop.
The servo hydraulic bar stop minimizes the break-out by progressively increasing force during the production.
The new technology is offered on various Hatebur machines, to optimize surface quality and avoid post-processing of parts.
