the machine manufacturer dr. fritsch sondermaschinen gmbh located in 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.
