Abstract

1,187,337. Abrasive wheels. NORTON CO. 28 Oct., 1968 [31 Oct., 1967], No. 51067/68 Heading C4V. [Also in Division C7] An organic resin bonded electrically conductive grinding wheel for electrochemical grinding contains abrasive grains in a thermoset resin matrix and contains 10 to 25% by volume of finely divided silver in the form of conducting paths. The resin may be a phenolic resin and the abrasive may be diamond, aluminium oxide or silicon carbide. The wheels may be made by forming a mix of resin powder with a curing agent such as hexamethylene tetramine and 10 to 25% by volume of silver powder having a particle size less than 10 microns, blending the mix with abrasive grains and moulding and curing the resin to a thermoset condition.
