Investigation on the grinding properties of high thermal ...

02-03-2020  In order to analyze the effect of graphite addition on the properties of vitrified bond CBN grinding wheel samples, different amounts of graphite (0, 2, 4, 6 wt%) were added to the vitrified bonder. When the graphite addition is 2 wt%, the refractoriness, fluidity, and bending strength of the grinding wheel samples are better than those of conventional vitrified bond grinding wheel samples.

Manufacturing Processes and Properties of Graphitic

The graphite particles resulting from grinding of expanded graphite are very anisometric (high aspect ratio) and extremely effective as conductive additive at low loadings. Specially granulated expanded graphite materials have shown advantages in the incorporation into polymers using industrial feeding and mixing equipment (Gilardi and Bonacchi 2011).
