  • Device for grinding spherical end face of roller-shaped workpiece
    Patent number: 9592582
    Abstract: An inner rotary retaining member has an annular outward rolling surface formed of part of a radially outward tapered surface centering on the central axis of a first rotary drive shaft. An outer rotary retaining member has an annular inward rolling surface formed of part of a radially inward tapered surface centering on the central axis of a second rotary drive shaft. The rolling surfaces are opposed to each other. A pocket that supports a workpiece such that the workpiece rotates and revolves as the retaining members rotate is formed at a portion of the carrier, the portion being positioned between the rolling surfaces. The central axis of the workpiece supported by the pocket is inclined relative to the central axis of the rotary drive shafts.
