At the end of this lesson the students would be able to
(i) identify need and purpose of grinding wheel specification
(ii) state the role of various compositional parameters of the grinding wheel
(iii) state the logical steps in selecting a grinding wheel
(iv) recognize need and purpose of grinding wheel conditioning
(v) illustrate various methods of wheel conditioning
28. Grinding wheels
Grinding wheel consists of hard abrasive grains called grits, which perform the
cutting or material removal, held in the weak bonding matrix. A grinding wheel
commonly identified by the type of the abrasive material used. The conventional
wheels include aluminium oxide and silicon carbide wheels while diamond and cBN
(cubic boron nitride) wheels fall in the category of superabrasive wheel.
28.1 Specification of grinding wheel
A grinding wheel requires two types of specification
(a) Geometrical specification
(b) Compositional specification
