Abstract

The invention relates to a device (1) for correcting the edging of a bevelled ophthalmic lens (100). It comprises a frame (2), a machining tool (7) mounted rotatably on the frame, a lens holder (10) equipped with means for clamping and turning (11, 12) the ophthalmic lens about a clamping axis (A1), and means for mechanically connecting the lens holder to the machining tool that allow a variation in the distance between the clamping axis and the machining tool. According to the invention, the machining tool has a working generatrix that is inclined with respect to said clamping axis, and mobility means (3) are provided to allow axial mobility of the ophthalmic lens with respect to the machining tool along said clamping axis, and first axial return means (30) for returning the ophthalmic lens towards the machining tool during machining.
