Title: Polishing machine for spectacle lenses

Abstract: A polishing machine for spectacle lense edges has a machine support having a guide column. A grinding wheel is seated on a grinding spindle driven by a drive, wherein the grinding wheel, the grinding spindle, and the drive are arranged on the machine support and wherein the grinding wheel has a rotational axis. A spectacle lens securing shaft having a drive and a rotational axis is provided. An upper machine part is connected to the machine support. The spectacle lens securing shaft is arranged together with the drive on the upper machine part. The spectacle lens securing shaft is movable with the upper machine part linearly up and down. The spectacle lens securing shaft is pivotable about an axis of the guide column that is spaced from the rotational axes of the grinding wheel and of the spectacle lense securing shaft and perpendicular thereto. A grinding chamber encloses grinding wheel and spectacle lens securing shaft. The grinding chamber is sealed with respect to cooling liquid thrown off the grinding wheel and has a cooling liquid drain guided to the machine support. A movable seal is positioned between the grinding chamber and the grinding spindle. It is also possible to have the grinding spindle moveable and the securing shaft stationary.
