Grinding machine of the optical glasses provided with a finish grinding wheel tilted and optical glass corresponding

摘要

This machine (11) comprises a lens support (19), provided with means (31) for driving in rotation by a lens (15) about a first axis (a - a ′) and a finish grinding wheel (49) with a peripheral groove (55) intended to form a bevel (16) on a peripheral surface (13) of the lens (15). The finish grinding wheel (49) is mounted rotatably about a second axis (c - c'). The machine (11) comprises means (23) of the relative displacement of the finish grinding wheel (49) with respect to the lens support (19) in order to bring the finish grinding wheel (49) in an active position of biseautage.les means of relative displacement (23) comprise means of inclination (43) adapted to tilt the second axis (c - c ′) with respect to the first axis (a - a').
