  • Multi-zone grinding and/or polishing sheet
    Patent number: 7004823
    Abstract: The invention relates to grinding/polishing sheet, which comprises 2 or more annular grinding/polishing zones (1-5) separated by intermediate annular distancing zones (6). One or more of the grinding polishing zones (1-5) comprises one or more non-continuous areas, that are part of an annular structure forming channels (8) in radial direction. The grinding/polishing sheet can be placed on a rotatable grinding/polishing disc for manual, automatic or semiautomatic preparations of materialographic samples. The invention also relates to a method for preparations of materialographic samples.

  • Apparatus for the grinding or polishing of workpieces
    Patent number: 4771578
    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.
