Summary

The Starrag Berthiez RVU 6200/600 is a CNC vertical grinding machine engineered for complete precision grinding of large components in a single setup. It is specifically suited for high-precision grinding applications, particularly in the bearing and aerospace industries, and supports several advanced configuration options including multiple grinding spindles and integrated hard metal machining. The system achieves concentricity and axial run-out accuracies below 5 μm and features a hydrostatically supported torque-driven rotary table to ensure vibration damping and stiffness.

Key Capabilities

• Vertical grinding with up to four water-cooled spindles, each capable of 45 kW and 18,000 rpm (application dependent)
• Grinding head tilt range from -5° to +275° with Hirth coupling locking
• Complete machining in one setup, with options for dressing units, wheel changers, and workpiece measurement
• Hydrostatic thrust bearing and torque motor table drive for improved accuracy and dynamic stiffness
• Optional hard metal turning and drilling in addition to grinding
• Process optimization via workpiece contact monitoring, process monitoring, and automatic or partially automated dynamic balancing
