A historical review of wear mechanisms and the structure of vitrified micro grinding wheels

Abstract

This paper presents a historical review of the wear and the structure of vitrified grinding wheels. This review describes the tribological issues surrounding use of vitrified grinding wheels and is discussed in three ways. The first explains the relationship between grinding wheel wear and wheel performance and discusses the interactions between abrasive grain and workpiece material and how it relates to grinding wheel performance; the second investigates the issues surrounding the composition of the vitrified bonding system and how it affects wheel wear, whilst the third explores the effect of reactions in vitrified bonds during thermal treatment of the grinding wheel that affect the performance of vitrified grinding wheels during subsequent processing of common engineering materials. The paper provides a timely review of the microstructural aspects of vitrified grinding wheels.Reference to this paper should be made as follows: Jackson, M.J.

Direct Photonic Fusion of Vitrified Bonding Materials

“…The current method of pre-fritting is to melt clays and feldspars at high temperature in a specially prepared platinum crucible so that the molten mass can be quickly quenched from high temperature to prepare the melt for fritting [3][4][5][6]. This is done by pouring the molten glass into a suitable coolant to control the rate of glass formation prior to milling and crushing to form the powdered glass frit [7][8][9][10]. The main aim of this work is to increase the rate at which the bonding materials are fused to form a glass or glass-ceramic bond using a directed photon beam, which not only prepares the fused mass for fritting, but can be further developed to form a vitrified network in a grinding wheel without the need for fritting, thus reducing the time it takes to produce a commercially available grinding wheel.…”

The Experimental Investigation of Stone Wear in Honing

“…But they didn't analysis the wear mechanism and its cutting property. In addition, there were lots of researches on grinding wheel wear [8,9], but it is not suitable in honing due to different contact area and contact status between the tool and the workpiece surface. This paper analyzes the wear mechanism and the cutting property by cylindrical honing experiments.…”
