Abstract

A method for machining particularly spectacle lenses by means of a machine which comprises at least one cutting unit and at least one turning unit in a common working space, wherein at least two spectacle lenses are machined at the same time in the working space, one of said spectacle lenses being cut while the other is turned. The machine frames of the cutting unit and of the turning unit are essentially decoupled from one another in terms of vibration and/or at least two machining units of the machine comprise workpiece spindle units for generating a transverse movement of the spectacle lens to be machined with respect to the respective tool, the workpiece spindle units being arranged essentially perpendicular to one another. As a result, it is possible for spectacle lenses to be machined in an extremely short time with high machining performance and with high surface precision and quality.
