    Abstract: The apparatus of this invention comprises a cup-shaped rotary grinding wheel adapted to move in its axial direction and having a sphero-concave working surface, a circular rotary driving cage formed along its outer periphery with radial cavities adapted to receive the workpieces to be machined in a continuous cycle, these workpieces being so disposed as to have a common point of intersection with the axis of rotation of the driving cage, and a rotary track supporting and carrying along the workpieces with a movement of rotation about their axes, the cage revolving concentrically to the track and being adapted to bring the workpieces beneath the working zone of the grinding wheel.

    Abstract: A high-speed hydrodynamic spindle assembly with an axialreciprocation or tacking movement, in which the spindle comprises, in the vicinity of one of its hydrodynamic bearings, a collar which is displaced between two rings and to which is transmitted the hydraulic pressure of the lubricating fluid of the bearings, so as to cause the tacking movement of the spindle, the pressure of the fluid and its regulation being obtained by an appropriate distribution device of the lubricating circuit of the bearings of the spindle.
