Removing glue residue on Apex B and MagnoMet carrier plates

In Magnetic Systems, carrier plates are used to provide a flat and well supported surface for silicon carbide (SiC) paper.  If these papers are used heavily or for long periods, the pressure sensitive adhesive (PSA) glue used can remain on the carrier plate after removal of the paper.  This can cause problems with flatness and …

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 …
