RK International is proud to announce that six of its premier manufacturing partners will be exhibiting at GrindingHub 2026, the leading international industry meeting place for grinding technology. Taking place at Messe Stuttgart, Germany, from May 5 to 8, 2026, the exhibition will bring together experts from all over the world to explore the latest trends in precision machining and automation.
RK International’s network of partners represents the pinnacle of innovation in grinding technology. Attendees at GrindingHub 2026 are highly encouraged to visit the following RK partner booths to witness their advanced machinery firsthand:
Robbi Group S.r.l. (Hall 10, Booth 10A31) will be showcasing the ROBBI Omicron 600 E T7 Universal Grinding Machine. Equipped with the latest-generation, highly intuitive T7 PLC, this simple Human Machine Interface features a SIEMENS touch screen operator panel, allowing users to easily program up to 12 different diameters within the same grinding cycle.
The T7 PLC enables automatic grinding wheel dressing cycles, complete with automatic compensation for all grinding dimensions after dressing.
The machine will be equipped with the new GTS Balance System Air Cutting System (demo version). Additionally, it will feature the new spindle with a speed of 30,000 rpm.
Dawn Machinery (Hall 7, Booth 7E21).
With over 30 years of development experience, Dawn Machinery specialises in vertical grinding and vertical form grinding. They will be showcasing the DN-302 dual spindle model, their customisable precision turnkey solutions feature double column symmetry structures and hydrostatic pressure turntables that achieve a rotating precision of less than 1μ. The dual spindle design balances efficiency and precision by allowing the use of both high and low rotation speeds.
GRIMA / Guan Yu Machinery (Hall 7, Booth 7D20).
GRIMA will highlight its advanced CNC Internal and External Cylindrical Compound Grinding Machine. The KG-500LE is designed for maximum efficiency, and this machine features dual grinding spindles—including a large external grinding wheel for end face grinding and dual independent internal spindle on their own slide. This allows for continuous processing, and the precise grinding of multiple features in a single setup.
Topking Technology (Hall 7, Booth 7A15).
Addressing the need for maximum space efficiency in busy production environments, Topking Technology will feature the X-6CAM CNC CAM Cylindrical Grinder, its most compact CNC non round grinder. This machine utilises an innovative cross slide structure integrated with linear motor and direct drive technology to deliver zero backlash, μm level precision for demanding CAM grinding. The X-6CAM is built on an artificial granite machine base for exceptional thermal stability and damping. Its superior C & X axis synchronisation makes it ideal for manufacturing polygon punches, small camshafts, eccentric pins, and medical components. To simplify operations, the X-6CAM is equipped with the SIEMENS SINUMERIK ONE control system, featuring a conversational interface that easily integrates with CAD/CAM software to program custom grinding graphics.
Joen Lih Machinery (Hall 9, Booth 9A70). A leading global manufacturer since 1988, Joen Lih known for its high precision CNC surface grinding machines and advanced semiconductor polishing equipment. Joen Lih will be showing the JL-52CNC-B, a compact surface grinding equipped with high-quality precision ball screws, Joen Lih’s surface grinders deliver unmatched stability and positioning accuracy, making them ideal for the rigorous demands of the medical, aerospace, automotive, and semiconductor industries.
Melchiorre S.r.l. (Hall 10, Booth 10A37)
For industries requiring the highest quality of flat surfaces, Melchiorre offers turnkey solutions in fine grinding, lapping, flat honing, and polishing. Their ELC series twin wheel machines feature a rigid, anti-vibration “C” frame construction and employ in process sizing gauges that guarantee extreme accuracy down to lower than 0.1 micron.
RK International is dedicated to supplying the manufacturing industry with precision machine tools and comprehensive grinding solutions. By partnering with leading global brands, RK International ensures its customers have access to the highest levels of precision, automation, and industrial innovation.
Visitors to GrindingHub 2026 are invited to explore Halls 7, 9, and 10 to experience the advanced capabilities of Dawn Machinery, GRIMA, Topking, Joen Lih, Melchiorre, and Robbi Group.
