text: devolopement of micro diamond grinding seminar report - SBM
  Diamond grindingis an important process for the machining of brittle materials such as glasses and ceramics to achieve nanometer levels of tolerances and surface finish. A repeatable optical quality surface roughness (surface finish<10 nm Ra) has been obtained in nanogrinding of hard steel by Stephenson et al. using a 76 μm grit cubic-Boron ...
  Metal bondeddiamond grindingwheels are widely used in thegrindingprocess, especial in ELIDgrinding. However, truing is difficult owing to the high toughness of metal bond materials and high hardness ofdiamondabrasives. To realize high precision and high-efficiency truing, we propose a newmicro-truing method consisting of electro-discharge truing and electrolysis-assisted mechanical ...

  CBN GeneratingGrinding An Economic Alternative
  CBN generatinggrindingis an economic alternative togrindingwith corundum. On one hand, however, profiling agrindingworm needs time and, on the other, it alters the geometry of the tool. Depending on the choice ofgrindingprocess, it has to be repeated in very short intervals in order to guarantee production at the same level of quality.
