Effects of the Wear Characteristics of Brazed Diamond Grits on Grinding Forces

Abstract:

Article Preview

Grinding forces, protrusion and wear of diamond grit have been studied in grinding granite with a single-layer brazed diamond wheel. The experiment results indicate that the primary wear progression of diamond grits in the whole grinding process follows the mode of whole, micro-fractured, macro-fractured and pull-out when grinding granite with the brazed diamond wheel. The proportions of the whole, fractured, pull-out, break flat and the mean height protrusion of grains are more closely related to grinding forces. The grinding forces decreased with the increasing proportions of whole and break flat grains, and the tangential and normal force components increased with the gradual wear of the brazed diamond wheel during a long-time grinding process.
