Berthiez RVU 6200/600
vertical grinding machine
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 60.3 hp at 18,000 rpm. (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.
Technological advantages:
– Hydrostatic guideways
– High degree of concentricity and axial run-out accuracies (< 1.5 μm)
– Precise and powerful table drive (torque motor)
– Solid design in monolithic grey cast iron
– Measuring cycles
