Abstract

The workpiece in its holder (H) is ground and/or polished by a tool (T) guided along a machining contour predetermined by the control unit. One rectilinear drive (I) is pivoted w.r.t. another (II) about a transverse axis (B), pref. by interpolative control of a third drive (III) to guide the tool from the edge to the centre of the workpiece and along a meridional line. An additional drive permits rotation of the holder about a central axis. The path of the tool is corrected by comparison of measurements at sample points with the predetermined contour. <IMAGE>
