ABSTRACT:
It is provided a drive and control device for a grinding machine of the type comprising a rotatable abrasive wheel (2), translating members (3) of the wheel (3) with respect to a rotating piece (4) to be ground, and restoring means (5) to reset the wheel (2) comprising a diamond-resetting member (6) and a balancing member (7), the device comprising sensor members (10) adapted to detect the piece roundness and electronic means (19) adapted to generate actuating signals (23) of the restoring means (5), in the presence of a roundness of the piece (4) different from a predetermined roundness. The process consists in grinding the piece and simultaneously measuring the piece diameter until achievement of a predetermined diameter, detecting the piece roundness, and operating said restoring means in interlocked relationship with the detected roundness.
