METHOD OF GRINDING TAPER ROLLER SPHERICAL END FACES Russian patent published in 2014 - IPC B24B11/00 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used in bearing production for grinding taper roller spherical end faces. Proposed method comprises fitting of conical roller by its conical surface in the sleeve for both to be revolved about their common axis in lengthwise mirror plane of grinding wheel. Spherical end is ground at 3-position tool with round turntable with three spindles equipped with collet and adjustable stops-pushers and with fixed cam. At first position, sleeve with conical roller is spring loaded at its end relative to stop-pusher and located at the spindle collet and displaced in axial direction to contact of the end of conical roller opposite the processed spherical end with stop-pusher and secured. At second position, rough and finish grinding of conical roller spherical end are performed with axial feed of grinding wheel. At third position, conical roller is pushed from the sleeve by said stop-pusher and fixed cam.

EFFECT: higher precision.
