Abstract (en)
[origin: EP0868972A1] The or each lens body (7) has a disposable tension edge (18) by which it is clamped for the grinding and polishing process before being removed at the end of the finishing process. The rough and finishing work on the lens body is carried out on one side and the lens body is then turned for the reverse side finishing. The lens body can be removed from a first clamping position and introduced into a second clamping position with a single interim holding and turning process. The finishing device has a machine stand with motorized drive and guide means for two vertically movable workpiece spindles (1,2) for a lens body blank.
