World market leader in grinding with CBN
We are grinding the future. Precisely. Intelligently. Sustainably.
The JUNKER Group at GrindingHub 2026 in Stuttgart, Germany
Our grinding solutions are key technologies for essential fields of the future: mobility in transition, the global energy shift, and the next generation of intelligent robotics. Whether in the powertrain of combustion, electric, or hydrogen vehicles, in the machining of components for wind, hydro, and solar power, or in the high‑precision production of complex parts for humanoid robots — our technologies make a decisive contribution to progress.
Experience our JUMAT 3S live at the tradeshow
The JUMAT 3S cylindrical grinding machine sets new standards in grinding high‑speed shafts. See for yourself the uncompromising precision of this technology. Whether longitudinal grinding of diameters or highly accurate grinding of shoulders and shaft ends with CBN — the JUMAT 3S delivers first‑class results.
We look forward to seeing you at our Booth C70 in Hall 10 from May 5th to 8th 2026.
