Berthiez Rvu 6200/600
The RVU grinding machines set new standards in highprecision 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 watercooled 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.
