ABSTRACT:
A machine for the surfacing of ophthalmic lenses has a working head in which a supporting finger is axially mounted on a pivotable arm. Pivoting of the arm causes the supporting finger to approach a working station. The arm carries actuating means for the supporting finger which control the approach of the finger towards the working station and control the pressure applied by the finger at the working station. In addition, damping means are provided for damping oscillation and vibrations of said supporting finger.
