Summary

The Starrag Berthiez RVU 3700/350 is a CNC vertical machine engineered for high-precision grinding and optional hard metal turning and drilling of large components. It offers complete machining capability in a single set-up with advanced features for minimizing rejects through high concentricity and axial run-out accuracy. Key differentiators include multi-spindle water-cooled grinding configurations, hydrostatic table bearings, torque motor drive, and provisions for automated wheel dressing, tool changing, and in-process measurement.

Key Capabilities

• Vertical grinding of workpieces up to 3,500 mm diameter with integrated rotary table
• Accommodation for up to four water-cooled grinding spindles (including CBN capability)
• Optional hard metal turning and drilling without part removal
• Table driven by torque motor and hydrostatic bearings for high torsional stiffness and vibration damping
• Programmable grinding head tilt from -5° to +275° (Hirth coupling locking)
• Integrated process monitoring, optional automatic balancing, and workpiece measurement
• Compatible with automated dressing units and grinding wheel changers
