Abstract: The device comprises the combination of two movable wedge members having each a moderately inclined plane, said wedge members being displaceable in two directions substantially at right angles to each other, the first wedge member abutting at the end of the approach stroke of the grinding wheel against a fixed stop of the frame structure of the machine, the second wedge member determining the end position of the first one, electric means for detecting the end position of the first wedge member in relation to the other one and controlling the finishing and planishing operations performed on the workpiece, by controlling the relative positions of the wedge members.
