Abrasive Cutter
7.0 Metallographic Cutting Basics
20
Philosophy:
1.
Cutting is the most important metallographic sample preparation step
2.
Minimize damage during sectioning
3.
Less sectioning damage = reduced number of grinding and polishing steps
Note: In some cases cutting damage cannot be removed by subsequent polishing operations
(especially for brittle samples)
Time Well Spent:
1.
Spend more time on sectioning in order to decrease overall sample preparation time
2.
Protect integrity of the specimen with proper sectioning
