Abstract
The invention relates to a polishing machine for spectacle lenses, including a least one workpiece spindle protruding into a workspace for a rotary drive of the spectacle lens about a workpiece rotational axis. At least one feed device lowers and raises a polishing tool relative to the spectacle lens. An oscillation drive unit moves the feed device back and forth in an oscillation direction, which during the polishing runs substantially transversely to the workpiece rotational axis. A swivel drive unit swivels the feed device about a swivel-adjusting axis which runs substantially perpendicular to the workpiece rotational axis and substantially normal to the oscillation direction. A swivel mechanism is provided to swivel the feed device, the oscillation drive unit and the swivel drive unit relative to the workpiece.
