Fine grinding and polishing tools Coated abrasives ⑤ Structure of coated abrasives PFERD TOOLS offers a wide selection of coated abrasive tools for working on different workpiece geometries and materials. ① Backing material ② Base bond ③ Coating bond ④ Abrasive grain ⑤ Active grinding layer ① ② ③ ④ ① Backing material Paper Cloth The main areas of application for coated abrasives with a paper base are in the woodworking industry and in trade, e.g. among carpenters, painters and decorators. Coated abrasives with a cloth base are predominantly used for metalworking. Vulcanized fibre When adapted to the corresponding applications, vulcanized fibre in various thicknesses is predominantly used for making fibre grinding discs. Vulcanized fibre is a very sturdy, robust backing material, and also very wear-resistant. ② + ③ bond When manufacturing coated abrasives, different resin bonds are used to fix the abrasive grain to the backing material. First, the backing material is coated with the base bond ②. After this, the abrasive grain is evenly scattered over the surface and aligned to achieve higher aggressiveness with the help of special procedures. The coating bond ③ ensures that the abrasive grain is fixed in place and protects the grain against the forces and loads resulting from the grinding process. ④ Abrasive grain Selecting the right abrasive grain has a great influence on the surface quality and efficiency. The most common abrasive grain materials are: Aluminium oxide A Numerous types of aluminium oxide are used as abrasives. These may be present in molten or sintered form. The hardness and toughness can be influenced by special manufacturing procedures or additives. Standard types of aluminium oxide and a “sharp-edged” grain shape are predominantly used for coated abrasives. Zirconia alumina Z Zirconia alumina is a fused mixture of aluminium oxide and zirconium oxide. In comparison to aluminium oxides, zirconia alumina exhibits lower hardness but greater toughness. The high proportion of zirconium oxide results in an extremely powerful self-sharpening effect and contributes to outstanding stock removal rates with cool grinding and a long tool life. Silicon carbide SiC Silicon carbide is synthetically manufactured abrasive grain which is very sharpedged, with low toughness and very high hardness. It is particularly suitable for work on titanium, aluminium, bronze, stone and plastics. Ideally suited for use in the aeronautical industry, especially where SiC is the only approved abrasive, e.g. for use on engine components. Diamond grain D Diamond grain is the hardest abrasive. It consists of pure carbon in a crystalline structure. For grinding tools, the diamonds used are generally produced synthetically at very high temperatures and under high pressure. The properties of diamond grain can be adapted for use in grinding tools through various synthesis conditions. Catalogue 4|9 4
