ABSTRACT:
A spectacle lens edge grinding machine either having a support which carries the template abutment and the grinding wheel, and which can be moved toward the fixedly mounted support shaft for the spectacle lens and the template, or a support which carries the support shaft for the spectacle lens and the template, and which can be moved toward the fixedly mounted template abutment and grinding wheel. In the first case, in the direction of movement of the support, a spring element which brings the support into its starting position acts on the support on that side remote from the support shaft for the spectacle lens and the template, and a tensioning device, which can be actuated and the tensioning force of which can be regulated, acts on the support on that side which faces the support shaft for the spectacle lens and the template. In the second case, in the direction of movement of the support, a spring element, which brings the support into its starting position, acts on the support on that side remote from the template abutment and the grinding wheel, and a tensioning device, which can be actuated and the tensioning force of which can be regulated, acts on the support on that side facing the template abutment and the grinding wheel.
