Rainford Precision will present micron-precise three- and five-axis machine tools from Kern Microtechnik at the MACH 2026 exhibition (NEC Birmingham, 20-24 April). In particular, Rainford will introduce the precision features of the newly launched Kern Micro HD+. This machine is the latest development in Kern’s Micro HD series, enhancing the patented micro-gap hydrostatic technology beyond linear axes to include fully hydrostatic B and C rotational axes.

The Micro HD+ offers significantly improved axial and radial run-out accuracy, increased dynamics through more powerful motors and topology-optimised structures, high rigidity thanks to hydrostatic rotary and swivel axes, and enhanced thermal stability via active cooling of all bearing components. The result is high-speed dynamic movement while maintaining micron-level precision over extended production runs.

With the machine’s compact platform, users canproduce workpieces up to 350mm diameter and 400mm in length, with an integrated tool changer that accommodates up to 210 tools. It achieves Ra0.05µm in serial production, often removing the need for finishing processes.

For the ultra-precise machining of larger parts, Kern has also introduced the Fortis HD (pictured). With a much larger working envelope, this machine incorporates a shaft-cooled high-speed spindle, a single-sided bearing mount, four-stage cooling and linear drives. The result is a machine with the micron precision and repeatability associated with the Kern HD, but in a substantial five-axis machining platform offering an X, Y, Zaxis travel of 780 x 420 x 450mm with 120° in the Baxis and 360° continuous rotation in the Caxis. Imagine retaining ultra-high precision with the flexibility to extend it to large parts – users now can with the Kern Fortis HD.
