A bond is an abrasive material used to held abrasive particles together. The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength. The different standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber, and metallic.

Fred Chester Bond - Wikipedia
Bond Work Index In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article.
