Grinding And Polishing Of Tertiary Curved Surfaces And Surfaces With Complex Shapes
(AREA)
Abstract
Grinding machine of the type referred to, characterized in that it comprises a fixed guide ring provided on its radially inner side with an arcuate cross-section path, a rotating shaft extending through the fixed track ring and carrying a rotating track ring a set of balls arranged between the fixed track ring and the rotating track ring and driving means between the shaft and the rotating track ring arranged in such a way that the reaction of the torque during the rotation of the shaft tends to force the ring rotary of track axially along the shaft, the track being formed on the rotating track ring in such a way that the axial force on said ring forces the balls out against the fixed track ring.
