A device () for cutting an ophthalmic lens (L) to be mounted onto a spectacle frame, includes: elements () for locking and rotating the ophthalmic lens about a locking axis (A); a tool holder which supports at least one first tool () rotatable about a rotational axis (A) and a second tool () rotatable about a finishing axis (A) and which has a spacing mobility (ESC) for the spacing apart thereof from the locking axis, a shifting mobility (TRA) for the axial positioning thereof along the locking axis, and a pivoting mobility (PIV) for adjusting the orientation of the rotational axis relative to the locking axis; and elements for controlling the three mobilities of the tool holder. The rotational and finishing axes are separate from one another.

Device for cutting an ophthalmic lens

A calibration template for calibrating a machining device that has blocking elements for blocking an ophthalmic lens, and machining elements for machining the ophthalmic lens, the template including a fastener portion suitable for being fastened to the blocking elements and a calibration portion arranged around the fastener portion. The calibration portion is made out of a material that is suitable for being machined by the machining elements, and presents firstly a plurality of shape patterns, and secondly a plurality of visual identifiers each visually associated with one of the shape patterns.
