Influence of diamond paste on abrasive finishing

Abstract

Abrasive finishing by diamond pastes is experimentally studied, with variation in the concentration of diamond grains and in the quantity of paste applied to the lap. In the experiments, the optimal quantity of abrasive paste applied to a lap of diameter 220 mm is determined: 75 mg. The productivity is somewhat higher in finishing by paste with a higher concentration of abrasive particles. The roughness of the machined surface is practically independent of the quantity and concentration of the diamond paste applied to the lap; it remains within the same class.
