Abstract
A device (10) for finish-machining of optically effective surfaces of workpieces, in particular spectacle lenses (L, L′), is disclosed, comprising at least one workpiece spindle (30, 30′), to which a workpiece can be clamped, at least one tool spindle (28, 28′), which is movable relative to the workpiece spindle and at which a tool (46) for machining the workpiece can be mounted, and a loading system (22) for bringing a workpiece to and taking it away from the workpiece spindle and bringing a tool to and taking it away from the tool spindle. The loading system comprises a loading head (82), which is separate from workpiece spindle and tool spindle, with at least one loading section (102, 102′) equipped with at least one mount (106, 106′) for a workpiece and at least one mount (104, 104′) for a tool, so that both the tool and the workpiece can be loaded in a time-saving single loading process.
