Vertical disc grinding machine Berthiez RVU 900/80

4-axisdrivenfor the aerospace industry

The RVU grinding machines set new standards in high-precision machining and are especially suitable for high precision grinding applications in the bearing and aerospace industries. The range can be equipped with up to four water-cooled grinding spindles which can achieve a performance of 45 kW at 18,000 rev/min. (according to the type of grinding wheel selected) The RVU facilitates a complete machining processing without interruption as optional dressing units, grinding wheel changers and workpiece measurement are available. Additional options for hard metal machining boring and workpiece measurement increase the possible applications of the machine series considerably. High drive power The machine has high drive power of 45 kW at speeds up to 18000 rpm. Extra spindles are available with 25 kW at 5000 rpm. Table drive by torque motor The hydrostatic thrust bearing and the rotary drive are driven by the torque motor. The hydrostatic table bearing with table driven by torque motor ensures a vibration-damping torsional stiffness. Process Optimization The means for process optimization range from workpiece contact monitoring, process monitoring, automatic or partially automated dynamic balancing up for workpiece measurement. Spindle head pivot axis The grinding head tilt can be adjusted in the range -5 ° to +275 °. Fixation is achieved by a Hirth coupling. High degree of concentricity and axial run-out accuracies The geometrical properties with a concentricity and axial running Multifunctional The machine offers the optional possibility for hard metal turning and drilling.
