RK International Machine Tools has supplied a new Jainnher JHC-18S NC1 single-axis centreless grinding machine to a leading European carbide tooling supplier, in a project that showcases a powerful partnership between two established UK companies.
The machine, part of the renowned JHC Series from Taiwanese manufacturer Jainnher, was configured for precision through-feed grinding of carbide blanks. This application demands exceptional wear resistance and surface finish, achieved through a high-performance diamond grinding wheel manufactured in the UK.
The precision grinding wheel was manufactured by
DK Holdings Ltd, a Kent-based manufacturer of precision diamond tooling located in Staplehurst. With a history dating back to 1959, DK Holdings is renowned for designing and manufacturing precision diamond and CBN profile wheels for challenging materials such as tungsten carbide, ceramics, and hardened steels. This bespoke tooling solution is critical in enabling the end user to achieve the tight tolerances and consistent, repeatable results required in carbide tooling production.
The project highlights the strength of the long-standing relationship between the machine supplier and the tooling manufacturer. John Emptage, sales director at DK Holdings, said: “RK International Machine Tools and DK Holdings have enjoyed a long partnership over the years and work well together. This project is a great example of mutual support, with RK supplying the precision platform and DK supplying the advanced tooling and abrasives to ensure the customer gets an optimised and completely bespoke grinding solution.”
Maintaining consistent tolerancesSimon Rood, RK International’s general manager, said: “The JHC-18S is a well-regarded model in the JAINNHER range, known for its rigidity and precision, making it ideal for both infeed and through-feed operations. The NC1 single-axis configuration provides precise control over the X-axis infeed, allowing for automatic compensation of wheel wear to maintain consistent tolerances and reduce downtime, a crucial feature for high-volume production runs.”
This delivery to a European carbide tooling supplier underscores the capabilities of UK companies and what a strong partnership can achieve. By combining RK International's expertise in machine tool supply with DK Holdings' leadership in super abrasive technology, global manufacturers can access high-precision grinding solutions tailored to the most demanding applications.
DK Holdings will be exhibiting at
MACH 2026, taking place 20–24 April, at the NEC, Birmingham, where visitors can learn more about its precision diamond and CBN tooling solutions for advanced grinding applications (Hall 17, stand 541).
