1. Abrasive : It is the material of the grinding wheel which does the cutting action.
2. Bond : It is the material of the grinding wheel which acts as a binder to hold the abrasive.
3. Types of Abrasive:

1) Natural : examples Quartz,emery,corundum,diamond etc

2)Artificial :

a) Silicon carbide :Trade names: Cry stolon, Electrolon & Carborundum.it is
denoted by 's' it is used for grinding low tensile strength materials like
cemented carbides ,cast iron etc.

b) Aluminum Oxide(al2o3) : Trade names: Aloxite,alundum& borolon.denoted by

'A'

USES: high tensile strength materials like carbon steels,high speed steels,wrought iron,annealed malleable iron etc.
