Abstract
In an apparatus for the grinding or polishing of workpieces, particularly metallographic samples, the grinding or polishing pressure is transmitted to the workpiece through a deformable transmission link which is strained by strain gauges of an activating member, which is then immobilized. The apparatus comprises means for sensing the elastic deformation of the transmission link and changes of that deformation during the progress of the process, whereby a simultaneous measurement of the grinding or polishing pressure and the depth of the layer of material removed by the grinding or polishing is obtained.
