Definitions

  • a known grid line abrasive material (US-A 2,740,238) is made of textile material with intersecting impregnated threads made with abrasive grain is covered so that passages between themselves crossing threads remain free. After curing it can Formed as abrasive material on both sides with high Grinding performance can be used, the passages for Serve removal of the sanded material. In practice becomes the grid grinding material for wet grinding with machines used. A preparation of the material for manual operation in dry grinding is not mentioned in the document and not found in practice.
  • Body panels are used in passenger vehicle construction cathodically dip-coated (electro-coating), one Base coat up to 30 ⁇ m thick is produced.
  • the Base paint has a certain roughness in which one another layer of paint, the so-called filler (primer), is good liable.
  • filler the so-called filler
  • the thickness of the base coat is applied cathodically not always even, d. H. areas also come with thick layer of lacquer.
  • the new grid line sanding material is also suitable for compacting such paint areas edit, d. H. reduce the thickness while doing one to produce fine basic roughness, which is roughly the same Basic roughness of the other cathodically dip-coated Surface corresponds.
  • the fabric threads 3, 4 form lattice elements whose Crossing points 6 lie in a plane 7, which the Represents grinding plane.
  • the crossing points 6 form one Grid and are surrounded by free spaces 8, where the Abrasive grain does not come into effect.
  • the size of the grinding wheel and the grit of the Abrasives are based on the intended Application. Grinding wheels come with one Diameters between 75 and 203 mm are considered. Others too geometric shapes with other dimensions can be used, which is why of lattice line abrasive in general can be spoken.
  • the Grinding wheel can also be used for finer surfaces Have abrasives above P1000.
  • an abrasive becomes Alox, aluminum oxide, for grinding body panels preferred because the generated roughness for the subsequent filler application is particularly suitable.
  • other applications can also use other abrasives are used, for example silicon carbide (Sica), with which can result in sharper abrasion. Alternatively, will Sica uses finer grain (in relation to Alox) to Grinding body panels.
