摘要:
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.

The method includes: automatic measurement of the marking characteristics of the lens in a measurement position in order to produce a marking reference of the ophthalmic lens; transfer of the lens in a second transfer movement from the measurement position to an intermediate position which is distinct from the measurement position; transfer of the lens in a third transfer movement from the intermediate position to a trimming position which is distinct from the intermediate position; locking of the ophthalmic lens on trimming elements (6); trimming the lens. The third transfer is carried out by third transfer elements that make up a sub-unit which is distinct and independent from other units or includes elements carrying out the second transfer, and trimming elements, wherein full blocking of the lens on the trimming elements is only completed after the third transfer.
摘要:
A method of working the periphery of an ophthalmic lens (L), the periphery of the lens possessing an edge face (C) and the method including edging the edge face of the lens by machining with a first grindwheel (31) mounted to rotate about an axis of rotation (A4). According to the invention, during the edging, in addition to being free to rotate about the axis of rotation, the first grindwheel possesses two degrees of freedom to move in tilting about two distinct pivot directions that are substantially transverse to its axis of rotation.
