Abstract
A device (1) for machining an ophthalmic lens includes a support for the ophthalmic lens and for driving it in rotation about a blocking axis (A1), a machining module (35) that can be swiveled relative to the support and driving the lens in rotation and that is suitable for pivoting about a swivel axis that is not parallel to the blocking axis of the lens, and at least one drill tool mounted to rotate on the machining module about a first axis of rotation. The machining device includes at least one other machining tool mounted to rotate on the machining module about another axis of rotation that is distinct from the first axis of rotation and that is stationary relative to the first axis of rotation.
