Definitions

  • the intermediate layer consists of a metal which is part of the binding of the fine abrasive grains of the abrasive coating on the peripheral surface. If this bond consists, for example, of a phenolic resin with a copper powder, the intermediate layer should preferably consist of a powder-metallurgical copper layer. It is sufficient if the intermediate layer has a thickness of only 0.1 to 0.3 mm, as can be achieved in a sintering process in a mold in which this intermediate layer and the binder with the fine-grained layers are used at the same time distributed small diamond is sintered.
  • FIG. 1 shows a grinding wheel 2 in its position relative to the workpiece 1 when grinding according to the quick-point method, in which there is an almost punctiform contact between these parts and thus a very high load on the grinding wheel 2.
  • the feed of the grinding wheel 2 takes place according to the arrow 3, the arrow 3 'indicating the direction of advance.
  • the outer end face area of the grinding wheel is loaded.
  • This end face region is designated by 6 in FIG. 2, the grinding wheel 2 again being advanced in accordance with the arrow 3.
  • the surface quality of the workpiece 1 is generated by the peripheral surface 4, while the end surface 6 causes the material to be removed.
  • the axis of rotation of the wheel runs parallel to the ground workpiece edge.
  • the circumferential surface of the grinding wheel is marked "4" in FIG.
  • the axis of rotation of the grinding wheel runs perpendicular to the ground workpiece edge.
  • the coarse-grained part of the covering is the peripheral surface of the grinding wheel and the grinding surface marked "4" is the end surface of the grinding wheel.
  • the feed direction runs parallel to the ground workpiece edge and is directed from left to right in FIG. 4.
  • a phenolic resin with nickel powder is provided, so that there is sufficient adhesion to the electroplated nickel for holding the diamond 9 '.
  • an intermediate layer 8 is provided in the embodiment according to FIG. 5 for better adhesion.
  • This intermediate layer 8 applied by powder metallurgy in the sintering process preferably consists of a metal which is also part of the bond of the abrasive coating 5. If, for example, this bond consists of a resin and a copper powder or steel powder, the intermediate layer 8 can also consist of copper or steel.
