Abrasive Cutting Techniques: Cutting Mode

Abrasive Cutting Techniques

Cutting metallic samples with a metallographic abrasive cutter is a very efficient way of creating samples, which typically minimizes damage in the cut surface reducing subsequent preparation times.  There are, however, different usage methods available that can improve cut quality or speed in a variety of circumstances. Chop cutting is the most common method used.  …

Don’t smear it! Avoiding surface deformation in polishing

Different materials have different characteristics, and understanding these can help in ensuring effective specimen preparation is achieved. Aluminum, copper, titanium, nickel and their alloys represent some of the most common engineering materials after steel. These metals can be quite ductile. Materials that deform easily can suffer from plastic deformation during grinding and polishing.  One form …

Getting stuck with embedding?

Low-Melting point metals such as zinc, lead and tin are not always easy to prepare. These metals are very soft and malleable, and attaining a scratch free finish can be challenging.  One of the more common problems during preparation of these specimens is embedding.  Embedding occurs when hard abrasive particles (or other contaminant) becomes fixed …
