Investigation of the performance characteristics of grinding wheel using low melting vitrified bonds

Abstract

The performance of a grinding wheel is greatly determined by its structure which in turn is influenced by the characteristics of the bonding material. Vitrified bonds were used in 50% of the wheels, which are mixtures of clay, feldspar and fusible materials. Vitrified wheels were fired at temperatures >1270°C. The main aim of this work is to focus on the feasibility of a low melting bonding material that would render the wheels a better or comparatively closer performance level than that of the conventional wheels, thereby attempting to reduce fuel and time consumption. Suitable low melting bonds were chosen based on the results of fusibility tests and chemical analysis, and their properties such as density, sound index (SI) and Young's modulus (YM) were evaluated. Performance characteristics were investigated through a cylindrical grinding test and compared along with the standard wheel. Attempts have been made to reduce the size of bonds to improve their properties, and the results obtained were promising.

Exploring the Influences of BaO Amount on the Wettability and Mechanical Behavior of Vitrified Bond Diamond Composites

“…Diamond is often used as a grinding material for machining hard and brittle materials because of its high hardness [1,2], while vitrified bond is widely wielded as a bonding agent for diamond abrasive-because of its high elastic modulus, high chemical stability, strong self-sharpening and low grinding heat-to manufacture abrasive tools that must possess a precise shape and certain strength [3][4][5][6][7][8][9][10].…”

An Investigation on The Mechanical Properties of FSP Processed Silicon Nitride Reinforced Aluminum Composite

“…In this study, Al8011 and Al 6063 based composite material has been developed using Si3N4 as ceramic particles by friction stir processing that clearly justifies the novelty of the current work. Now a day the demand of low density high strength material is too high in the field of medical 33) , aerospace 34) , automobile 35) and defense 36) . Further the FSP technique has been better than traditional stir casting process 37) .…”
