Abstract

1,194,110. Grinding wheels. NORTON CO. 14 Oct., 1968 [13 Oct., 1967], No. 48542/68. Heading C4V. [Also in Division C7] A grinding wheel for electrochemical grinding consists of a porous structure of a ceramic bond, abrasive grains and finely divided metal forming electrically conducted paths through the structure and the pores of the grinding portion of the wheel containing thermoset polymer to an extent of at least 20% of the pore volume. Preferably at least 75% of the available pores are filled with resin. The metal particles may be of silver which may have average size ¢to 1 micron and be present to the extent of approximately 8% by volume of the overall mix when the abrasive grain is of size 80 grit. The abrasive particles are of 1 to 0 grit 9, volume per cent of silver is satisfactory and 400 grit wheels 4À8% of silver is required. Platinum particles may be used as well as copper particles which are preferably protected against oxidation by a silver or other coating. The abrasive may be of alumina. The inorganic bonding material may be of clay and glass and may also include sodium carbonate and boric acid. The resin may be a phenolic, a polyester, a polyurethane, a polyimide or a melamine resin.
