Model 656 Dimple Grinder

  • Dimple grinding offers a fast and reliable mechanical method of pre-thinning to near electron transparency (in some cases to electron transparency) greatly reducing ion milling times and uneven thinning
  • Dimple grinding offers a means of producing quality TEM specimens having a large central area only a few microns thick surrounded by a robust outer rim. This eliminates special handling techniques for fragile specimens.
  • Dimple grinding and subsequent polishing with felt wheels provides an exceptionally smooth surface reducing the prospect of surface irregularities developing in the final ion beam thinning operation, increasing the yield of the electron transparent area.
  • A dual measuring system, digital micrometer and analog dial indicator, provides accurate depth and thickness control to within 1 micron.
