Claim Text:
1. A device for the finish-processing of optically effective surfaces of, in particular, spectacle lenses as workpieces, comprising: a pivot mechanism having a pivot frame pivotably mounted to provide a closed operating position, in which a working space located below the pivot frame creates a cavity for processing the workpieces and an open access position; in which the cavity is open to provide access to the workpieces, at least one workpiece spindle, which projects into the working space and by way of which a workpiece to be processed is drivable to rotate about a workpiece axis of rotation, at least one feed device for a tool, by which the tool is movable towards the workpiece and away therefrom, an oscillatory drive unit, by which the feed device is reciprocatingly movable in a direction of oscillation which when processing takes place extends substantially transversely to the workpiece axis of rotation, a pivot drive unit, by which the feed device is pivotable about a pivot adjusting axis extending substantially perpendicularly to the workpiece axis of rotation and substantially normal to the direction of oscillation, and wherein the feed device, the oscillatory drive unit, and the pivot drive unit are all mounted to the pivot frame which collectively pivots the feed device, the oscillatory drive unit and the pivot drive unit relative to the workpiece spindle between the closed operating position and the open access position.
