Wear of the blade diamond tools in truing vitreous bond grinding wheels - Part I. Wear measurement and results

The wear of stationary blade diamond tools used to generate a precise and i ntricate form on the vitreous bond grinding wheel is presented. Two types o f blade tools made of rod and particle diamond were used. A method to measu re the wear of the blade diamond tool in the Rm-scale range using the size difference of two parts ground before and after truing was introduced. Two sets of experiments with four truing feeds and four tool traverse speeds ac ross the grinding wheel were conducted on the rod and particle blade diamon d tools, respectively. Experimental results showed the wear rate of blade d iamond tools was improved at higher truing feeds and traverse speeds due to the brittle fracture of the abrasive and vitreous bond.
