Abstract

An abrasive article comprises abrasive grains and negligibly abrasive non-metallic inorganic grains, of British Standard 60 mesh or coarser, which function as grinding assistants, bound together by a synthetic resin, which may contain finely powdered filler material. The granular grinding assistants may be composed of an inorganic compound or a mixture of compounds containing sulphur, chlorine, fluorine, or phosphorus, e.g. iron pyrites (iron sulphide), troilite, covellite, &c., chalcocite, chalcopyrite, rock salt, cryolite, fluorspar, bone ash or phosphate rock (calcium phosphate). The only synthetic resin specified is phenol-formaldehyde, and the only abrasive grains specified are of fused alumina. Uses.-Grinding wheels, especially for grinding steels. In the Provisional Specification another form of iron sulphide, viz. marcasite, is mentioned as a grinding assistant.ALSO:An abrasive article comprises abrasive grains and negligibly abrasive non-metallic inorganic grains of British Standard 60 mesh, or coarser, which function as grinding assistants, bound together by an organic band, e.g., rubber, synthetic resin or shellac, which may contain finely powdered filler material. The granular grinding assistants may be composed of an inorganic compound or a mixture of compounds containing sulphur, chlorine, fluorine, or phosphorus, e.g., iron pyrites, troilite, chalcocite, covellite, chalcopyrite, rock salt, cryolite, fluorspar, bone ash or phosphate rock.
