Abstract
A machine for grinding the edges of a spectacle lens, including shaft halves for holding the lens therebetween, a grinding wheel for machining the periphery of the lens, a support for the template that is held by one of the shaft halves, and a measuring head that is connected to a computer and serves for measuring the position of the front and rear sides of the lens at the grinding or contact point, in the vicinity of the periphery of the grinding wheel, relative to a prescribed plane. The measuring head has a fork-like configuration, including fork legs that are disposed parallel to one another and to the prescribed plane, and are spaced from one another by a distance that is greater than the greatest width of the periphery of the lens, whereby the shaft halves with the lens, or the grinding wheel with the measuring head, carries out an oscillating back and forth movement relative to the other.
