Definitions
- the invention relates to an abrasive body with abrasive grain, such as corundum, a binder, such as phenolic resin, or a sintered magnesite bond and active fillers or fillers.
- abrasive grain such as corundum
- a binder such as phenolic resin
- active fillers or fillers such as phenolic resin
- grinding wheels e.g. for abrasive cutting, from three essential components, namely the cutting abrasive, a binding agent that holds the abrasive grain and active fillers.
- the present invention is concerned with the problem of grinding active fillers.
- these fillers are intended to increase the service life of the grinding tool and reduce the heating of the workpiece and grinding tool and thus avoid thermal damage. With some difficult to machine materials, e.g. unalloyed, low-carbon steels or titanium, these fillers are the prerequisite for economical processing.
- an optimal abrasive filler must have favorable transition temperatures and chemically reactive cleavage products, that it and its secondary products should have the lowest possible toxicity and thus high MAK levels, that it should be inexpensive and that its processing in abrasive products is therefore industrial not only be possible under laboratory conditions.
- Object of the invention is to provide grinding with grinding active fillers that grinding with good a good processability of the grinding compound - combine technical characteristics and low 14AK values.
- the grinding-active fillers are metal halides or metal complex salts with the following structure: where A is an alkali metal or ammonium ion, x is a number from 0-10, Me II is a divalent metal, namely Mn, Ca, Mg, Zn, Sn, Cu, Co, Ni, y is a number from 0-2, Me III is a trivalent Metal, namely Al, B, Ti, z is a number from 0-2, Hal is a halogen, E is a number from 1-10; n is a number from 0-10, B is an alkali metal or ammonium ion, f is a number from 0-1, B is an alkali metal or ammonium ion, f is a number from 0-1, C is a divalent element (e.g. Ca, Mg, Zn, Sn, Mn), g is a number from 0-1, e is a number from 1-2, m
- the grinding-active fillers are manganese halides or manganese complex salts.
- manganese halides are manganese chlorides of the following formulas: where x is a number from 0 to 10.
- manganese complex salts have the following formula: K 2 MnCl 4 .
- the abrasive grain was initially moistened with the resol, then the bond consisting of the novolak and the filler was added and this mass was thoroughly mixed for 5 minutes. The mixture was stored for 5 hours and then pressed. The grinding wheels were cured at 180 ° C for 24 hours.
