Abstract
A grinding wheel is defined by the type of abrasive material, bonding material, grain size, structure of the wheel, and
grade of the wheel used for the machining of a component. These factors decide the grinding efficiency of the wheel and surface
finish quality of the machined component. A wide range of abrasives are being used in modern era to overcome necessities in
machining of various make of components. Abrasives ranging from the economic verses of aluminium oxide to the likes of
super-abrasives such as cubic boron nitride and the expensive diamond grains are used for machining as well as surfacing
purposes. Over the years, research has depicted that no distinct abrasive material can meet all the requirements of grinding
applications. The mechanical and physical properties of a particular abrasive material make it suitable for a certain application.
This paper focuses on the selection of a suitable abrasive for grinding application which is of utmost importance in
order to obtain enhanced surface finish and grinding performance.

1. Introduction
The word “grinding” can be defined as a process of abrasion. Material removal is done by using sharp abrasive
grains either on the sides or on the face of bonded grinding wheels. Chipping of the work material occurs due to the
sharp grains. Basically, a grinding wheel can be called as a precision tool, composed of abrasive grains, which is
held together by a bonding material. The cutting points of the wheel are provided by the abrasive grains, which helps
in cutting the material to the required dimensional accuracy.
