A new grinding wheel was developed focusing at the anchoring force of abrasive grains against the bridging matrix. Cast iron powder was utilized to form the skeleton matrix. Stronger anchoring effects were achieved by bonding the abrasive grains and the skeleton cast iron matrix through chemical reaction between the abrasive grains and skeleton cast iron matrix. The newly developed grinding wheel exhibits longer life and higher grinding efficiency then conventional ones.
