Abstract (en)
[origin: EP1864753A1] A machine has a workpiece spindle (24) that rotatably drives the plastic spectacle lens about a rotation axis. A fast-tool assembly (36) moves a turning cutter (48) to and away from the lens. The spindle and assembly are movable relative to each other in a transverse to the rotation axis. A second fast-tool assembly (38) is adjacent to the first assembly and has a graver (50) with a punctiform end that faces the lens. The graver is carried by and movable by the second assembly to and away from the lens. A marking is produced through needling engagement of the graver with the lens.
