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 …

Out-of-Box Concept with Mount Fixturing, EZ Clamp

EZ-Clamp

Holding a metallographic sample both steady and level during hardness testing is essential to ensure accurate and repeatable results. To make this mount both convenient to use, versatile and effective can be a challenge. An innovative fixturing method was developed by Buehler’s Wilson Hardness Testing Group over 10 years ago. This fixture is not widely …

Verwendung von Referenzstiften bei der Präparation präziser Querschliffe von Durchkontaktierungen auf Leiterplatten

Targeting Through Holes in Printed Wiring Boards (PWB) – Use of Reference Pins

Bei Verwendung der Buehler-PC­MET- und PWB­MET-Probenhalter für die Präparation von Querschliffen von Durchkontaktierungen muss der Gesamtschleifabstand mit einem Referenzstift eingestellt werden. Wie in der Abbildung gezeigt, ist dieser Abstand bei der Standardvorrichtung auf 3,81mm vorgegeben. Referenzpins zur Herstellung präziser Querschliffe von Durchkontaktierungen auf Leiterplatten Durch das Schleifen bis zum Erreichen von Diamantanschlägen in der Vorrichtung …
