     Automation of high-performance rolling mills

      Achenbach is a high-tech mechanical engineering company that belongs to the most
      important manufacturers of rolling mills for non-ferrous metals. For many years, the
      company has relied on the Bachmann M1 automation system to provide the control
      technology for its systems. Beside its performance, Achenbach has been convinced by the
      reliability and openness of the M1 system.

The availability of a system determines its
productivity to a large extent. This means that
the failure rate and possible downtimes must
both be minimized. And so for Achenbach, the
mechanical and electrical design were significant
selection criterias for the automation system.
"In terms of our operational conditions, we have
identified in particular thermal and mechanical
influences, such as vibration, as failure criteria,"
reports Roger Feist on the results of extensive
investigations in the field. Achenbach was
especially convinced by the Bachmann M1
system’s robust mechanical design, its fan-free
operation at ambient temperatures of up to
60°C and the exclusive use of semiconductor
memories instead of (moving) magnetic data              Helping determine the evenness of the strip:

Ultimately, manageability, that is, operability
and serviceability, help determine the
productivity and availability of a system. Here,
too, Achenbach sets standards. Thanks to the
open system structure of the M1, proprietary
solutions in programming could be avoided

                        Automation of die-casting machines

     Die-casting, an industrial casting process, is used for the mass production of structural
     parts made from metals such as aluminium, zinc or magnesium. For the past ten years
     Oskar Frech GmbH + Co. KG, based in the Swabian town of Schorndorf (Germany), has
     been using the Bachmann M1 system for the automation of its die-casting machines.

     A steel rim in five steps

              The development of machines that produce complex formed metal components while
              at the same time maintaining maximum productivity and profitability was and is the
              declared goal of the company Fontijne Grotnes BV throughout its more than 100 year
              history. The company is located in the Netherlands, in Vlaardingen near Rotterdam, and
              with its approximately 140 employees develops and produces – amongst other things
              – customer-specific machinery to produce steel wheel rims, and is one of the leading
              companies in Europe in this field. However, increasing demands placed on the load
              capacity of the produced parts in the automotive area especially call for ever-narrower
              manufacturing tolerances and reproducible high quality.

              In order to meet these demands, the engineers
              at Fontijne Grotnes use comprehensive
              simulations to verify and optimize the
              production process long before their machines
              are constructed.

In the first step of the production process, the
steel raw material is uncoiled from the large
coils it is delivered on and cut to size (cut-to-
length line). The cylindrical hollow forms are
shaped out of these pre-cut parts (preparation
line). In the line that follows, the blanks are
flared, profiled and expanded to the required
circumference and brought into their final shape
(profiling line).

The final product i.e. the steel wheel rim is
already recognisable. When assembling in the
assembly line, the leak tightness of the rim is
checked, the hole for the valve is punched and
the mounting disc is fitted and MIG-welded.
Finally the rims are stove-enamelled.

The main advantage of implementing safety
concepts in software compared to hardwired
solutions lies in the fact that programming needs
to only be done once. After successful verification
and validation it is saved to an archive and from
there can be used multiple times. Wiring on the
other hand must be completed for every device.
On top of that it is possible with a few easy steps
in the Safety Editor to leverage useful parts from
an existing concept and manage them as user-
specific templates. This in turn allows for a better
overview while reducing the error rate and saving
time in future programming projects.

     Exceptional capabilities

              The M1 system enables users to set up networked automation systems in a simple and
