Abstract
The invention relates to a method and a device for machining the peripheral edge of spectacle lenses and for optionally applying a subsequent facet thereto. The device comprises a driven spectacle-lens holding shaft which holds the spectacle lens and a machining tool which can be moved in a controlled manner in relation to the spectacle-lens holding shaft. The torque of the spectacle-lens holding shaft is measured and said holding shaft is driven at a constant rotational speed if and for the length of time that the torque is less than or equal to a predetermined value. The torque of the spectacle-lens holding shaft is decreased optionally to a standstill if and for the length of time that the torque exceeds the predetermined value.
