Machine for Machining of Optical Workpieces made of Plastic, in Particular Spectacle Lenses

A machine for machining optical workpieces made of plastic, in particular spectacle lenses, which each have two workpiece surfaces and a workpiece edge therebetween, comprising

• at least one first machining station which is configured for machining a workpiece for shaping the workpiece edge by at least one first tool with a geometrically defined cutting edge,
• at least one second machining station which is designed for wet machining of the workpiece for shaping at least one of the workpiece surfaces by at least one second tool with a geometrically defined cutting edge while supplying a cooling lubricating liquid, and
• a movement device arranged functionally between the at least one first machining station and the at least one second machining station for positioning a workpiece holding head at the respective first or second machining station, which movement device is adapted to hold the workpiece without a block piece,
• characterized in that the first and second machining stations of the machine have first and second work spaces which are separate from one another and are each encapsulated with respect to the surroundings, wherein the first machining station has a housing, which specifically delimits the first work space, and is constructed for substantially dry machining of the workpiece at the workpiece edge.
