Holding Strength of Bond to Diamond Grain within Vitrified Abrasives

Abstract:

This paper first analyzes the characteristics of holding strength of ceramic adhesive to diamond grains within vitrified abrasives grinding wheel, subsequently put forwards a calculating method of holding strength based on the data of the samples tensile strength test and fractography analysis. The holding strength mechanical model and the mathematic model are presented in this paper, which is figured out by load strength analyzing and idealized assumptions. Considering the holding strength computational complexity a set of software was designed to calculate the strength with the Excel data sheets exported from the tensile strength test and micro image analysis. Its flow diagram was shown in this paper.
