Abstract: 1453671 Bonded abrasive tools TOYODAKOKI KK and T ASAEDA 14 March 1974 [20 March 1973] 11480/74 Heading C4V A metal-bonded grinding tool comprises the combination of a rim of porous material and a compact of abrasive grains press-formed around and in contact with the rim, the grains being bonded together and to the rim by metal which has been chemically precipitated throughout the said combination on the surfaces of the abrasive grains and in pores on the rim so as to provide a uniform and continuous bond. The grinding tool may be prepared by preparing a rim of porous material, cleaning and preparing the abrasive grains for a subsequent metal coating, press-forming the abrasive grains in contact with the rim of porous material and forcibly passing the chemical plating liquid through the body comprising the compact or abrasive grains and the rim of porous material to cause precipitation of the metal on the surfaces of the abrasive grains and in the pores of the rim of porous material so as to produce a uniform and continuous bond. Suitable abrasive grains are diamond, boron nitride, Alundum (Trade Mark), White Alundum, Carborundum, and green Carborundum. Mixtures of suitable grains may also be employed. The abrasive grains may be treated by boiling with hydrochloric acid, washing, boiling with aqueous caustic soda and washing. The sensitizing treatment may be effected by immersing the grains in an aqueous solution of tin chloride for 10 minutes and washing. An activating treatment may then be applied in which the grains are immersed in an aqueous solution of palladium chloride for 5 minutes and washing. The porous rim may be of a sintered alloy which may be bronze or an iron sintered alloy. The outer cylindrical rim may be turned to the correct shape and then treated by etching to restore the porous outer surface. The rim may then be washed with acetone, alkali, acid and finally with water. The chemical plating liquid may be supplied from an inner portion of the rim in an outward radial direction and then through the press-formed compact.
