A machine for grinding the edges of glass articles such as slides for carrying specimens to be observed under a microscope. These glass articles are held in a suitable frame with the edges which are to be ground in engagement with a rotary grinding wheel. During the grinding operations a transmission is operatively connected with the frame to move the latter radially with respect to the axis of the grinding wheel so that in addition to the rotary movement of the grinding wheel there is the radial movement of the frame with the glass articles held thereby.
