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 …

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

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

When using the PC-MET and PWB-MET targeted grinding fixtures from Buehler, it’s necessary to set the total grinding distance from a reference pin on which the sample is mounted to the feature of interest.  In the standard equipment, this distance is set to 0.150” as shown in the diagram. The perfect target is reached by …

Petrographic Preparation – how and why to frost your slide

Petrography Frosted Slide

In petrography, and in some other analyses, it is necessary to examine the structure of materials using light transmitted through the specimen.  For this to work effectively on rocks and minerals, the sample needs to be extremely thin – typically 5-30 microns.  Many applications need the thickness of the specimen to be extremely consistent, in …

DiaMet Hardness Software – Schweißnahtprüfung durch Vickershärte

Weld Image

Schweißnahtverbindungen sind heutzutage in der Automobil- und Luftfahrtindustrie nicht mehr wegzudenken. Durch Schweißnähte werden meist metallische Komponenten zusammengeführt und bilden eine Konstruktion, die dann in der Produktion und Montage mit anderen Unterbaugruppen montiert werden. Die Schweißnähte müssen extreme Belastungen wiederstehen können, da sie die Schwachstellen der Kontruktion darstellen. Die Schweißnahtuntersuchung ist somit ein sehr wichtiger …
