Summary:Compsn. for grinding tool mfr. contains >=1 inorganic salt binder (A), in addn. to metallic filler and organic binder (B), e.g. a phenoplast or polyimide. Fusion temp. of (A) is below hardening temp. range of (B). Component proportions, by vol., are 12.5-37.5% abrasive, 30-60% metallic filler, 5-30% (A), balance (B). Tools can be used for grinding heat-resistant alloys, hard alloys, cemented and nitrided steels. nA) addn. increases grinding tool strength. Abrasive wear is reduced. On heating, (A) acts as a flux and destroys oxide layers on metallic filler particles, thus helping to increase tool conductivity. L'INVENTION CONCERNE L'USINAGE PAR ABRASION.LA COMPOSITION FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT UN ABRASIF, UNE CHARGE METALLIQUE ET UN AGGLOMERANT ORGANIQUE, ET EST CARACTERISEE EN CE QU'ELLE COMPREND EN OUTRE UN AGGLOMERANT MINERAL, CET AGGLOMERANT ETANT AU MOINS L'UNE DES SUBSTANCES DU GROUPE DES SELS AYANT UN POINT DE RAMOLLISSEMENT CORRESPONDANT A LA PLAGE DE TEMPERATURE DE POLYMERISATION DE L'AGGLOMERANT ORGANIQUE. LADITE COMPOSITION CONTIENT: ABRASIF, DE 12,5 A 37,5; CHARGE METALLIQUE, DE 30 A 60; SUBSTANCE DU GROUPE DES SELS, DE 5 A 30; AGGLOMERANT ORGANIQUE, LE SOLDE.LES OUTILS EN QUESTION PEUVENT ETRE UTILISES NOTAMMENT POUR L'USINAGE PAR ABRASION DES MATERIAUX DIFFICILEMENT USINABLES, TELS QUE LES ALLIAGES REFRACTAIRES ET DURS, LES ACIERS CEMENTES ET NITRURES.
