Abstract

225,436. Wade, H., (Carborundum Co.). March 6, 1924. Drawings to Specification. Moulding grinding-wheels and other tools. - Grinding-discs, wheels, stones, &c., which may have a cloth or paper backing, are formed by mixing with the abrasive grains a resin solvent, for example, furfural, in sufficient quantity to coat the surfaces of the grains, which are then mixed with a powdered phenol resin, for example that known under the registered Trade Mark " Redmanol." The mixture is placed in an iron mould and moulded under a pressure of approximately 900 pounds per square inch, after which it is removed from the mould and baked for fifteen hours at a temperature of about 350‹ F.
