Everything relating to grinding technology for experts from all over the world – that is what GrindingHub will offer in Stuttgart from 5 to 8 May 2026. After two successful editions, the organiser VDW (German Machine Tool Builders’ Association) will continue the trade fair’s success story in co-operation with Messe Stuttgart and the Grinding Conference.

Dr Markus Heering, managing director of the VDW, says: “GrindingHub has become established as the central hub for the grinding technology industry. The energy and commitment of every participant in the previous editions of the trade fair were overwhelming.”

Marie-Sophie Maier, managing director of Adelbert Haas GmbH, has been an exhibitor from the very beginning: “This trade fair is the ideal platform for our company: internationally oriented, technologically leading and tailored precisely to our industry. At GrindingHub we meet the right trendsetters with whom we can jointly shape the future of grinding technology.”

Markus Kiffe, managing director of Kiffe Engineering GmbH and a visitor to GrindingHub 2024, shares this enthusiasm: “We’ll definitely come back again because you always see interesting things here and obtain exciting ideas, establish numerous contacts and hold a large number of discussions.”

In 2026 GrindingHub will again feature a wide range of grinding machines, abrasives, software tools, process peripherals, and measuring and test systems. Companies wanting to exhibit their innovations and products at the leading trade fair for grinding technology can now register online.

Heering concludes: “It’s always inspiring to see how the industry – despite and even because of the economically challenging times – comes together and plays a mutually supporting role. We’re convinced that GrindingHub 2026 will again be a great success.”

A UK filtration expert has launched new dust and fume extraction technology from sister company Absolent. Filtermist, which specialises in ensuring workshop air is clean and safe to breathe, is now offering the AD range of dust extraction units, which maximises the advantages of Absolent’s ‘True Downflow’ technology.

“Several pain points were identified and addressed during the three-year development project,” explains Robert Wiktorén, Absolent Air Care Group’s chief product officer. “As an existing manufacturer of dust collectors under our Absolent, Dustcheck and Diversitech brands, we knew there was a need in the market for a new way of thinking about dust and fume extraction. Traditionally, dust collectors have been sized using generic data to select suitable filter type, filter area and air speeds between filter elements. The resultant footprints have been comparatively large.”

He continues: “When filters need changing, even the best current designs require the filter-retaining mechanism and moving parts to be in the ’dirty side’ of the unit, exposed to contamination. This is not a great environment for moving parts and requires a tool to reach the filter elements furthest away. Our True Downflow technology combines the verticality of the filter elements with a top to bottom air flow. This combination optimises the effect of gravity and ensures that dust coming out of the filter elements during pulse-jet cleaning is forced down to the disposal solution in the hopper.”

The roll-out of the first AD phase includes three models: the 0.5 (which holds two deep pleat cartridges); the 1.0 (four filters); and the 1.5 (six deep pleat filter elements).

The highest precision is achieved through the optimal interaction of machine, tool and machining process. Japanese-Swiss company Big Kaiser therefore relies on the combination of hard turning and grinding on a Super Precision T51 SP MSY machine when manufacturing its high-precision tool holders in Rümlang near Zurich.

The list of machine manufacturers that produce high-precision hard turning machines is not long. One of the most prominent companies in this field was machine manufacturer Hardinge, which developed the Super Precision series. This series is now part of the portfolio of Kellenberger Switzerland AG.

Thanks to their rigidity and stability, the CNC high-precision lathes in the Super Precision series are suitable for hard turning as well as for combined hard turning and grinding operations in the production of complex workpieces in a single set-up. Measurement reports certify that the T series has a continuous machine accuracy of 3 µm, workpiece roundness of 0.25 µm (T42) and 0.70 µm (T65), a repeat accuracy (on all axes) of 0.76 µm, and an achievable surface finish of better than Ra 0.15 µm or Rz1.

“Of all the machine manufacturers we approached, only Hardinge guaranteed us process reliability,” says Big Kaiser’s head of supply chain Marcel Stettler. “That was courageous and ultimately convinced us.”

The new T51 SP MSY was ordered in December 2018 and delivered in summer 2019. A robot handling system for fully automated production was subsequently installed in October 2020.

For the combined turning/milling and grinding operations required for the complete machining of HSK tool holders, the T51 SP MSY machine features a grinding unit with driven tools developed for Big Kaiser, which has an inclined position. This inclined position is of decisive importance for the finish grinding of taper and shoulder features.
