Grinding Technology Grinding Hub to highlight efficient fine machining processes

From MA Alexander Stark

Unmanned production, 24/7. For many manufacturing companies, this is one of the key factors for success in this highly competitive field. This has been the case for turning, milling and drilling technologies for some time, but increasingly now also for fine machining. Exhibitors at Grinding Hub will be providing a first glimpse of their solutions for achieving significant increases in productivity and reproducibility levels.

Frankfurt am Main – Fine machining requires a great deal of intuition. That is why many companies still take care of grinding and polishing manually. However, this can quickly become a source of high costs and inconsistencies, especially in series production. Automation solutions deliver reproducible quality at all times. With its combination of grinding technology, automation systems and software, Grinding Hub 2022 will provide comprehensive information on this challenging field.

Top quality surfaces are essential in metal and woodworking as well as in the automotive and aerospace industries. Fine machining in particular is still performed by hand in many cases, as human sensitivity is difficult to imitate. But manual polishing, grinding and brushing is time-consuming and exhausting work. Automated processes offer an attractive alternative, allowing flawless surfaces to be created faster and at lower cost. At the same time, they relieve people from monotonous and dusty work. The trade fair will present new tools for automated machining which compensate for force and positional inaccuracies, allowing near-perfect results to be achieved.

“The closed loop ensures superior manufacturing quality as well as minute profile tolerances – together with maximum user-friendliness. Even with extremely challenging workpieces, such as grinding wheel bases, turbine blades or grooving inserts, it has proven to be a robust solution on the shopfloor,” says Marie-Sophie Maier-Wember, Managing Director of Haas Schleifmaschinen in Trossingen. Software is becoming a driver of precision working because mechanical forces are constantly in play during grinding, especially towards the edges of the grinding tools. These forces affect the interaction between the workpiece, grinding tool, clamping device and grinding machine. They result in ever-increasing levels of inaccuracy, which has an adverse effect on workpiece quality — especially if the system does not allow for a continuous exchange of data between the workpiece and the grinding machine. A self-controlling process based on an integrated measuring solution effectively prevents this loss of precision.

Automation solutions have long been an integral part of the product portfolio of the Hamburg-based engineering company Blohm Jung. A topical example of this is the tool changer for the current series of grinding machines. Designed for maximum cost efficiency, the solution offers users numerous benefits from reduced setup times to virtually unmanned processing — even of complex workpieces. “However, automation is only one of the key factors involved in increasing productivity,” explains Stefan Springer, Head of Product Management at Blohm Jung. “Machine connectivity is also gaining in importance, as the future of industrial production will be networked.” Machines are communicating with each other, exchanging data, controlling and regulating each other. This makes processes run more efficiently and increases productivity.

The advantages of the latest products and solutions can be clearly explained and discussed in direct meetings with the experts. Do we have the right equipment for the next project? Which is the best fine machining technique for a specific component and how exactly does the software help me with the manufacturing processes?
