State advantages and limitations of honing process. 

1 Answer

Answer :

Advantages:

1. Less complex or low cost fixtures.

2. It is highly accurate.

3. It can be used for both long and short bores.

4. It maintains original bore centerline.

5. Any material can be finished regardless its hardness.


Limitations:

1. Honing is though of as a slow process.
