Definitions

  • a support unit 4 is provided, for example, with a slide unit of handling technology (industrial robot) or the like which can be adjusted in the direction of the arrow X and X 'by means not shown.
  • the head pieces 1, 2 and 3 arranged on the carriage unit 4 can be adjusted relative to the carriage unit 4 in the direction of the arrows Z and Z 'in addition to the movement oriented in the arrow direction X, X'.
  • the above-mentioned movements of the individual elements in the direction of the arrow X, X 'and Z, Z' are preferably carried out independently of one another, but there is also the possibility of combining the movements with one another if necessary.
  • the suction power on the head piece 2 is temporarily switched off and the diamond grains 12 ′′ are opened the assigned plate 11 '' or powder layer.
  • the diamond grains 12 ′′ can be released from a suction plate arranged on the second head piece 2 by means of a brief, slight blast of compressed air. The blast of compressed air may, however, only be so great that the placement of the diamond grains 12 ′′ on the correspondingly assigned plate 11 ′′ is ensured while maintaining a certain geometric formation.
  • the formation of the diamond grains 12 ′′ is achieved by the special design of the suction plate arranged on the second head piece 2.
  • the above-described alternate layering of the individual sintered metal platelets 11 ′′ and the layers of the diamond grains 12 ′′ is described and repeated until a predetermined height of the grinding wheel 45 to be produced is reached.
  • head pieces 2 can be arranged on the carrier element 4.
  • the head pieces 2 are each formed with differently designed suction plates for a differentiated layer formation of diamond grains. The formation of the individual suction plates with the different formations for the diamond grains 12 ′′ will be described in detail in connection with FIG. 8.
  • the bores 38 arranged on the inner arch edge 40 ′′ are offset with respect to the bores 37 arranged on the outer arch edge 40 ′.
  • the bores 37 and 38 are assigned further bores 37 'and 38' arranged on the center line M and further bores 37 '' and 38 ''.
  • the two lateral end pieces 36, 36 'of the suction plate 40 are designed as an edge oriented straight to the center (not shown) of the circular ring.
  • the suction plate 41 largely corresponds to the suction plate 40 described above and the bores 37 'and 38' arranged on the center line M and the correspondingly assigned bores 37 '' and 38 '' can be seen. Deviating from the suction plate 40, no holes are provided in the suction plate 41 on the outer and inner curved edges 41 ′ and 41 ′′.
