the machine manufacturer dr. fritsch sondermaschinen gmbh from fellbach is market leader in the development and production of machines for the diamond tool industry. with the new machine generation slm 910 | slm 920 for the automatic soldering of segments with silver solder on separating discs, dr. fritsch undertook a paradigm shift. until now, the company relied on motors, frequency converters and controls from siemens. the new machine was to be converted to the latest technology from beckhoff and software from mrm².

with us, mrm² automatisierungstechnik gmbh, one of the leading specialists for beckhoff and twincat3 in baden-württemberg was selected. after the first discussions with mrm², it was quickly clear to us: "we'll do it together," says uwe funk, head of development at dr. fritsch.

our task was to replace all frequency converters and motors of the machine, and to replace the previous siemens control system with a beckhoff control system. for the control system, we developed a new, future-proof architecture and application software, as well as a contemporary visualization based on the latest standards. a particular challenge was to maintain at least a similar "look and feel" to existing plant visualizations, despite all the new features, so that users can easily get to grips with operating the plant again, despite real changes.

fully automated, diamond segments are now pressed and held onto the saw blade with a single or double gripper. the saw blade and segment are heated via an inductor, and the solder is melted. after cooling, the saw blade and segment are inseparable and perfectly soldered together.

"the close cooperation with mrm² was a big plus, as our ideas could be incorporated into the planning and implementation of the software at any time. we now have a very well planned and structured software that will make our work much easier in the future," adds uwe funk.

the swiss company beyond gravity ag is a supplier of space products and the world’s leading supplier of composite technology payload fairings and structures for launcher vehicles. new production sites have been established in emmen (ch) and decatur (usa). ariane 5, ariane 6 short and long and vega payload fairings are produced there.

most of the production plants in switzerland and two plants in decatur are equipped with electrical engineering from mrm². at the emmen production site there is a laying table for fibre mats, two plants for equipping fairing half-shells and a highly complex, fully automated plant for processing the fairing half-shells, the horizontal integration station. 17 synchronously running axes, repetitive accuracies of 0.02mm over a length of 26m, tool changing systems including program management, further synchronously running and externally monitored drive systems, multi-user operable visualizations and highly networked different systems. all systems are developed and programmed on the codesys software platform.

the techdax group jenoptik ag the techdax group jenoptik ag produces sophisticated optical precision systems. the precision lenses and optics to be manufactured are very complex in their production processes. ultra-precisely manufactured tools, cleanroom systems and high-precision measuring procedures are used.

the complete systems for the production of the special lenses from mrm² are characterized by perfect robot systems in combination with optimal space conditions and high-precision milling systems. they are locally processed, aligned, milled in several operations, ionized cleaned, glued, sorted and stacked. the future is virtual, and we are pleased to have been part of it.

the company tibo tiefbohrtechnik gmbh manufactures high-precision deep hole drilling machines for almost all areas of the manufacturing industry. a sophisticated control concept with modular components for a flexible customer-specific scope of performance and intuitive operability with a 15" multitouch operating panel characterize deep hole drilling machines from tibo.

the highly specialized application software is designed in such a way that a single program and a single circuit diagram form the basis for all 3 possible complete machine types, each with more than 20 options. updates or further options are thus automatically available for all 3 machine types.

meba metall-bandsägemaschinen gmbh is a family-owned company and has specialised exclusively in metal band sawing machines since 1958. today, meba is one of the world's leading suppliers of metal band sawing machines.

since a lot of new software is always necessary for complete solutions, meba needs a reliable and competent partner on its side. in the field of software engineering and software structuring, the automation people could give the classic machine builder a decisive customer advantage in the field of software engineering. also in the field of building automation, the existing and very inflexible system was completely replaced by a new codesys-based system. the possibilities are unlimited and the tasks could be effortlessly implemented in an open control system.

in order to better protect our environment, water and wastewater management plays a central and very important role. in this context, electrotechnical automation is also an important component when it comes to safely executing and monitoring processes.

for the community of syrgenstein in the district of dillingen, southern germany, we carried out the retrofit of the electrical engineering of the municipal wastewater treatment plant.

old control systems for which spare parts were no longer available were successively replaced. the control cabinets were completely redesigned and equipped with the latest technology, and the installation was optimized in terms of space. the difficulty was to keep the entire plant reliably functional while individual control systems and control cabinets were gradually replaced by new ones. for example, it had to be ensured that the old communication bus was not disconnected in order to avoid error messages on the main control system that remained until the end, which would have led to disruptions in the operating process. step by step, the controls of the blower station, the agitators, the feed/return sludge and the higher-level head control were replaced. all messages now converge on a central scada system. the existing mosaic circuit diagram of the entire plant was retained in order to provide visitors with a good overview of the plant.

"the complete wastewater treatment plant is now technically up to date and equipped for many years of efficient operation!" franz seeger, responsible for the bachtal wastewater treatment plant, is pleased. "due to their many years of experience in the field of water supply and disposal and their know-how, both in dealing with the old moeller control system and the new eaton control system, mrm² was exactly the right partner for us."

stadtwerke freudenstadt gmbh & co. kg guarantees the supply of energy and water, especially in Freudenstadt and its suburbs, for more than 14,000 customers. security of supply is therefore an absolute must in heat generation as well. all combined heat and power plants and energy generators of stadtwerke freudenstadt are intelligently controlled, because efficiency must be guaranteed despite all security.

for the very complex electrotechnical control systems for the district hospital, the keppler school and the panorama bath with the newly built outdoor pool, stadtwerke relied on the competence of automation people and were thus optimally supplied, just as the customers of stadtwerke themselves are. intelligent systems for buildings and facilities in the properties are a prerequisite for efficiency and security of supply. we are pleased that we have been able to support our friends in freudenstadt for many years.
