Summary

The Starrag Berthiez RVU 1600/140 is a CNC vertical grinding and turning center designed for high-precision grinding, particularly for applications in bearing and aerospace manufacturing. Its core function is to provide complete, multi-process machining—including grinding, hard metal turning, and drilling—in a single setup, with demonstrated capability for sub-5 µm concentricity and axial runout. Key differentiators include up to four water-cooled grinding spindles, high dynamic table drive (torque motor), large working enclosure, and advanced process integration with in-process measurement and optional dressing units.
