Different Approaches to Grinding Abrasive Materials
Fine Grinding Fine grinding abrasive materials is typically needed to create particle sizes in the minus 50 mesh range (297 microns) down to about 95% minus 325 mesh (45 microns) Some of these sizes are typically referred to as talc, flour, pulverized, or ballmill fine grades Abrasive material and hardness of grinding wheel are two important factors affecting the grinding efficiency and quality In this study, two kinds of abrasive grains (ie, zirconium corundum (ZA) and brown fused alumina (BA)) were used to produce eight grinding wheels, among which five with different contents of abrasive grains and four with different hardness levels Rail Effects of abrasive material and hardness of grinding Both silicon carbide and aluminum oxide abrasives are very hard and brittle, and as a result they tend to form sharp edges These edges help the abrasive to penetrate the work material and reduce the amount of heat generated during the abrasion This type of Abrasives How do abrasives work?

First, let’s look at the makeup of a typical grinding wheel (Figure 1) Abrasive grains are generally considered to be the primary component and can be traditional oxide or other ceramic material, diamond, or cBN (cubic boron nitride) A bonding medium holds the abrasive grains within the wheel structure and provides bulk strength Free space, or porosity, is intentionally included within •In addition to abrasive grains and bond material, grinding wheels contain air gaps or pores •Volumetric proportions of grains, bond material, and pores can be expressed as: P g P b P p 10 ©2002 John Wiley Sons, Inc M P Groover, “Fundamentals of Modern Manufacturing 2/e” Figure 251 Typical structure of a grinding wheel ©2002 John Wiley Sons, Inc M P Groover GRINDING AND OTHER ABRASIVE PROCESSES grinding wheels may be used for light stock removal and finishing in one operation (24 grit for blending; 36 grit for finishing) Cotton fiber combined with abrasive and flexible bonding material is especially good for bronze, aluminum and thin sheet steel; Blending welds; Deburring; Seethrough fiber discs (60 to 120 grit for light deburring)Choosing the Right Abrasive Product for Welding and Metal
How grinding wheel is made material, history, used
Abrasive grains constitute the central component of any grinding wheel, and the hardness and friability of the grinding materials will significantly affect the behavior of a given wheel Hardness is measured in terms of a relative scale developed in 1812 by a German mineralogist named Friedrich Mohs On this scale, extremely soft talc and gypsum represent hardnesses of one and two, and Abrasive definition, any material or substance used for grinding, polishing, etc, as emery, pumice, or sandpaper See moreAbrasive Definition of Abrasive at DictionaryThe whetstone comprises abrasive grains, a bonding material, and pores The abrasive grains play the role of a cutting edge, the bonding material fixes and supports the grains, and the pores act as a chip pocket to help discharge of cutting chips In whetstones where the bonding material is a resinoid bond or metal bond, there are not normally any pores The process whereby a grinding wheel Abrasive Grain an overview ScienceDirect Topics
