Abstract
The present invention relates to an apparatus for machining glass lenses, wherein said apparatus comprises the following members: a housing; a machining chamber located in said housing; a shaft for maintaining a glass lens and a machining device both arranged in the machining chamber; a cover for outwardly closing the machining chamber; a support for transporting a non-machined lens towards the shaft for maintaining the glass lens when the cover is shut; a detector for measuring the position of the non-machined lens as well as its angular position on the support, said detector being located in the area between the cover and the shaft for maintaining the glass lens; and a control device in the form of a computer. When grinding the glass lens using the machining device, the control device uses the data provided by the detector about the situation and the angular position of the non-machined lens in the shaft for maintaining the glass lens.
