ABSTRACT:
An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, includes: a lens rotation shaft which holds and rotates the lens, the shaft being rotatable about a first axis; a grooving grinding stone which forms a groove in an edge surface of the lens; a holder which rotatably holds the grooving grinding stone; an inclination mechanism for relatively inclining the holder with respect to the lens rotation shaft to change inclination of a rotation axis of the grooving grinding stone with respect to the first axis; and a controller for obtaining desired inclination of the rotation axis of the grooving grinding stone correspondingly to a radius vector angle at each processing point of grooving locus, thereby controlling the inclination by the inclination mechanism.
