a) Coarse
b) Medium
c) Fine
d) Very Fine
View Answer
Explanation: ‘8’ represents grain size, which is coarse. Second value in the specification represents grain size.
3. Grinding wheel is specified as “A 600 K 5 B 17”. Grain size of a wheel will be
a) Coarse
b) Medium
c) Fine
d) Very Fine
View Answer
Explanation: ‘600’ represents grain size, which comes under very fine grain size. Second value in the specification represents grain size.
