Summary

The Berthiez RVU 1350/125 is a CNC vertical grinding machine designed for high-precision grinding of large workpieces, specifically for applications in the bearing and aerospace industries. Its core function is to deliver precise grinding operations with concentricity and axial run-out accuracies under 2 μm, and it supports complete machining—including grinding, hard metal turning, and drilling—in a single setup. Notable technical features include water-cooled spindles with up to 45 kW power at 18,000 rpm, hydrostatic table bearing for vibration-damping, and a wide grinding head tilt range enabled by a Hirth coupling.

Key Capabilities

• Vertical grinding of parts with swing diameter up to 1350 mm
