Diamond grinding points vacuum-brazed bonding The vacuum-brazed bonding provides a much better adhesion of grits to the carrier thanks to direct fusing. These tools are particularly suited for fibre glass reinforced materials GFR and CFR plastics (in aircraft construction and shipbuilding), tungsten carbide green components (unsintered carbide), ceramics (e.g. valve cover rings for car engines), coal products (e.g. brake discs, carbon brushes), cast materials.
Benefits of this new bonding: • Very good stock removal thanks to higher grit protrusion • Allows production of more complex forms, e.g. inner radiuses • Markedly better grit retention force • Cooler grinding thanks to larger chipping spaces
