The pencil edging diamond wheels used for lateral automotive glass grinding are composed of a mixture of metal powders (bond) and dispersed super-abrasive diamond grits (having a 100 μm average size). The metallic bond consists of a ductile alloy (sintered Ag+Cu+Ti powder mixture) and a hard skeleton (W and cast iron). The principal characteristics expected are a good wear resistance as well as a good cutting quality. In order to reproduce the industrial thermal cycle of the sintering manufacturing process in a traditional furnace, this cycle was simulated by dilatometric tests on green pellets of simplified metal powder mixtures. The aim was to determine the sintering behaviour of each component of the metallic bond.
