Abstract
An apparatus for processing edges of ophthalmic lenses with a gripping device for the ophthalmic lens. The gripping device grips the ophthalmic lens in such a manner that the edge to be processed in accessible, with a turning the gripping device with the gripped ophthalmic lens turns about an axis of rotation. A tool is held in a support and is brought into contact with an edge area of the ophthalmic lens to be processed for the processing procedure. The tool is a lathe tool, with the support being conveyed by a control unit in at least one direction during a rotation of the gripping device corresponding to a prescribed shape of the ophthalmic lens.
Claims15
An apparatus for processing edge areas of an ophthalmic lens, the apparatus comprising:
- a gripping device for gripping the ophthalmic lens in such a manner that the edge area of the ophthalmic lens to be processed is accessible,
- a turning device for turning said gripping device with the gripped ophthalmic lens about an axis of rotation,
- a support,
- a lathe tool supported by the support and adapted to be brought into contact with the edge area of said ophthalmic lens to be processed for effecting a processing operation, and
- a control unit for controlling the support and for conveying the lathe tool towards and away from the ophthalmic lens in a direction perpendicular to the axis of rotation during a rotation of said gripping device corresponding to an axially unsymmetrical circumferential contour of said ophthalmic lens, and
- wherein said ophthalmic lens is processed by said lathe tool during a plurality of rotations of said gripping device.
