Definitions

the invention relates to a method according to the preamble of claim 1.
the object of the invention is to achieve this advantageous grinding behavior even with conventionally produced grinding or honing bodies.
ceramic-bonded disks with a relatively large pore volume primarily a structure 7 or larger, are treated with metal soaps until the volume of the metal soaps introduced corresponds to at least 5% of the total volume of the grinding disk.
plastic-bonded grinding wheels provided that they have a corresponding structure.
Metal soaps are to be understood here as neutral or basic salts of mono- or polyvalent metals or amines. Such soaps are advantageously used which, on the one hand, are compatible with the environment and coolants, and on the other hand have the highest possible melting point. Salts and soaps of the following fatty acids, whose melting point (F) is also given, are to be mentioned here: with calcium, zinc, aluminum, sodium or lithium.
Montanic acids C22 ... to C34 with melting points above 80 ° C can also be used as fatty acids, as can hydroxy compounds of the listed compounds, for example 12-oxystearic acid.
sodium or lithium soaps can be dissolved in hot water.
the grinding wheel can be soaked with such solutions, if necessary in vacuo.
the disc should also be warmed (approx. 90 ° C) to avoid premature gelation of the solution.
the water After the solution has been gelled by cooling, the water must be removed, preferably by freeze-drying. This step can be followed by a further impregnation with subsequent drying in order to introduce the desired amount of soap into the glass body.
