Grinding Wheel: A Definite Guide For You (With PDF)

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.
