Achenbach OPTIMILL® Copper & brass rolling mills

Achenbach copper & brass rolling mills reliably produce best strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. In the segment rolling mills they are designed as two- or four-high hot rolling mills, in the segments cold strip and thin strip rolling mills as six- or four-high rolling mills and in the segment of foil rolling mills as six-high rolling mills and thereby always tailored to the specific purpose.For each new strip rolling mill or those to be modernized, a holistic approach to perfectly synchronize mechanics, hydraulics, automation and drive technology in their complex interaction is applied.

The outstanding performance is achieved by automation with Achenbach OPTIROLL®.

The Achenbach OPTIPURE® Media Systems for economically and ecologically efficient exhaust air purification, rolling oil filtration and rolling oil rectification complement the machinery for an optimum rolling process.

The cloud-based platform Achenbach OPTILINK® opens the way to the overall system networking of the various value creation stages and therefore to the optimization of the entire production process.
